GENERAL SAFETY RULES

WARNING:
Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

PRODUCT SPECIFIC SAFETY RULES

• Miter saws are intended to cut wood or wood-like products, they cannot be used with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
• Use clamps to support the workpiece whenever possible. If supporting the workpiece by hand, you must always keep your hand at least 100 mm from either side of the saw blade. Do not use this saw to cut pieces that are too small to be securely clamped or held by hand. If your hand is placed too close to the saw blade, there is an increased risk of injury from blade contact.
• The workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece into the blade or cut "freehand" in any way. Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
• Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece "cross handed" i.e. holding the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
• Do not reach behind the fence with either hand closer than 100 mm from either side of the saw blade, to remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.
• Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence, and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.
• Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece. Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.
• Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.
• Ensure the miter saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduces the risk of the miter saw becoming unstable.
• Plan your work. Every time you change the bevel or miter angle setting, make sure the adjustable fence is set correctly to support the workpiece and will not interfere with the blade or the guarding system. Without turning the tool "ON" and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.
• Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or longer than the table top. Workpieces longer or wider than the miter saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.
• Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.
• The cut-off piece must not be jammed or pressed by any means against the spinning saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged against the blade and thrown violently.
• Always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to bite and pull the work with your hand into the blade.
• Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.
• If the workpiece or blade becomes jammed, turn the miter saw off. Wait for all moving parts to stop and disconnect the plug from the power source and/ or remove the battery pack. Then work to free the jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage to the miter saw.
• After finishing the cut, release the switch, hold the saw head down, and wait for the blade to stop before removing the cut-off piece. Reaching with your hand near the coasting blade is dangerous.
• Hold the handle firmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position. The braking action of the saw may to be suddenly pulled downward, causing a risk of injury.
• Save these instructions. Refer to them frequently and use to instruct other users. If you loan someone this tool, loan them these instructions also.

ADDITIONAL SAFETY RULES

• Use the proper extension cord. Make sure your extension cord is in good condition. Use only a cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire gauge size (A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
• Inspect tool cords periodically. If damaged, have repaired by a qualified service technician at an authorized service facility. Repair or replace a damaged or worn cord immediately. Stay constantly aware of cord location and keep it well away from the rotating blade.
• Inspect extension cords periodically and replace if damaged.
• Polarized plugs. To reduce the risk of electric shock, this tool has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
• Know your power tool. Read the operator's manual carefully. Learn the applications and limitations as well as the specific potential hazards related to this tool.
• Always wear eye protection with side shields which is marked to comply with ansi Z87.1 when using this product. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.
• Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
• Keep guards in place and in good working order.
• Use the right direction of feed. Feed work into a blade, cutter, or sanding spindle against the direction of rotation of the blade, cutter or sanding spindle only.
• Never leave tool running unattended. Turn the power off. Don't leave tool until it comes to a complete stop.
• Use only correct blades. Do not use blades with incorrect size holes. Never use blade washers or blade bolts that are defective or incorrect. The maximum blade capacity of your saw is 7-1/4 in.
• Before making a cut, be sure all adjustments are secure.
• Never touch blade or other moving parts during use.
• Double check all setups. Make sure blade is tight and not making contact with saw or workpiece before connecting to power supply.
• Firmly clamp or bolt your tool to a workbench or table at approximately hip height.
• Make sure the miter table and saw arm (bevel function) are locked in position before operating your saw. Lock the miter table by tightening the miter lock knob. Lock the saw arm (bevel function) by securely tightening the bevel lock knob.
• Never move the workpiece or make adjustment to any cutting angle while the saw is running and the blade is rotating. Any slip can result in contact with the blade causing serious personal injury.
• Avoid awkward operations and hand positions where a sudden slip could cause your hand to move into the blade. ALWAYS make sure you have good balance. NEVER operate your miter saw on the floor or in a crouched position.
• Never stand or have any part of the body in line with the path of the saw blade.
• Do not turn the motor switch on and off rapidly. This could cause the saw blade to loosen and could create a hazard. Should this ever occur, stand clear and allow the saw blade to come to a complete stop. Disconnect your saw from the power supply and securely retighten the blade bolt.
• If any part of this miter saw is missing or should break, bend or fail in any way, or should any electrical component fail to perform properly, shut off the power switch, remove the miter saw plug from the power source, and have damaged, missing or failed parts replaced before resuming operation.
• Always turn off the saw before disconnecting it to avoid accidental starting when reconnecting to power supply. NEVER leave the saw unattended while connected to a power source.
• This tool should have the following markings:
  • To reduce the risk of injury, user must read the operator's manual.
  • Wear eye protection.
  • Keep hands and body out of the path of the saw blade. Contact with the blade will result in serious injury.
  • Check guarding system to make sure it is functioning correctly.
  • Do not perform any operation freehand.
  • Never reach around the saw blade.
  • Turn off tool and wait for saw blade to stop before moving workpiece or changing settings.
  • Disconnect the saw from the power source before changing blade or servicing.
• Always carry the tool only by the carrying handle areas.
• This saw can tip over if the saw head is released suddenly and the saw is not secured to a work surface. ALWAYS secure this saw to a stable work surface before any use to avoid serious personal injury.
• Always make sure the saw blade has clearance of all obstructions before turning the saw on.

SYMBOLS

ELECTRICAL

DOUBLE INSULATION

Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

WARNING:
The double insulated system is i ntended to protect the user from shock resulting from a break in the tool's internal wiring. Observe all normal safety precautions to avoid electrical shock.

NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the tool to your nearest authorized service center for repair. Always use original factory replacement parts when servicing.

ELECTRICAL CONNECTION

This tool has a precision-built electric motor. It should be connected to a power supply that is 120 V, AC only (normal household current), 60 Hz. Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the tool does not operate when plugged into an outlet, double check the power supply.

EXTENSION CORDS

When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the product will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used.

When working outdoors with a product, use an extension cord that is designed for outside use. This type of cord is designated with "WA" or "W" on the cord's jacket.

Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

WORK CLAMP

WARNING:
In some operations, the work clamp assembly may interfere with the operation of the blade guard assembly. Always make sure there is no interference with the blade guard prior to beginning any cutting operation to reduce the risk of serious personal injury.

See Figure 12.
The work clamp provides greater control by clamping the workpiece to the table surface. It also prevents the workpiece from creeping toward the saw blade. This is very helpful when cutting compound miters. Depending on the cutting operation and the size of the workpiece, it may be necessary to use a C-clamp or other suitable clamp instead of the work clamp to secure the workpiece to the miter table prior to making the cut.

To install the work clamp:

• Place the shaft of the work clamp in either hole on the miter table base.
• Rotate the work clamp knob to move it up or down as needed to secure the workpiece.

TO INSTALL/REPLACE THE BLADE

See Figures 13 - 14.
The blade is shipped installed on this miter saw model. Instructions have been included for reference when changing or replacing blades.

WARNING:
A 7-1/4 in. blade is the maximum blade capacity of the saw. Never use a blade that is too thick to allow outer blade washer to engage with the flats on the spindle. Larger blades will come in contact with the blade guards, while thicker blades will prevent the blade bolt from securing the blade on the spindle. Either of these situations could result in a serious accident and can cause serious personal injury.

• Unplug the saw.
• Raise the saw arm.
• Rotate lower blade guard up and back to expose the blade bolt.
  NOTE: Raise the blade guard until resistance is met and continue to raise the guard until it reaches the locked open position.
• Depress and hold the spindle lock button and rotate the blade bolt until the spindle locks. (See Figure 13)
  
• Using the hex end of the blade wrench, loosen and remove the blade bolt.
  NOTE: The blade bolt has left hand threads. Turn blade bolt clockwise to loosen.
• Remove outer blade washer.
  NOTE: The inner blade washer is integrated into the spindle and cannot be removed.
• Wipe a drop of oil onto the spindle and outer blade washer where they contact the blade.
• Fit saw blade inside lower blade guard and onto spindle. The blade teeth point downward at the front of saw as shown in figure 14.
  
• Replace outer blade washer. The double "D" flats on blade washers align with flats on spindle.
• Depress and hold spindle lock button and replace blade bolt.

NOTE: The blade bolt has left hand threads. Turn blade bolt counterclockwise to tighten.

CAUTION:
Always install the blade with the blade teeth and the arrow printed on the side of the blade pointing down at the front of the saw. The direction of blade rotation is also stamped with an arrow on the upper blade guard.

• Tighten blade bolt securely.
• Lower the blade guard.
• Raise and lower the saw arm to ensure lower blade guard functions correctly.

WARNING:
Make sure the spindle lock button is not engaged before reconnecting saw into power source. Never engage spindle lock button when blade is rotating.

REMOVING/REPLACING THE THROAT PLATE

See Figure 15.

WARNING:
The throat plate must be below the miter table. If the throat plate is too high or too low, the workpiece can catch on the uneven edges resulting in binding which could result in serious personal injury.

OPERATION

WARNING:
Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.

WARNING:
Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.

WARNING:
Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or accessories not recommended can result in serious personal injury.

APPLICATIONS

This product has been designed only for the purposes listed below:

• Cross cutting wood, wood composition and plastic (do not cut metals, ceramics, or masonry products.)
• Cross cutting miters, joints, etc. for picture frames moldings, door casings, and fine joinery
• Bevel cutting and compound cutting of lumber and moldings.

NOTE: The blade provided is fine for most wood cutting operations, but for fine joinery cuts or cutting plastic, use one of the accessory blades available from the dealer.

WARNING:
Before starting any cutting operation, clamp or bolt the compound miter saw to a workbench or an approved workstand. Never operate the miter saw on the floor or in a crouched position. Failure to heed this warning can result in serious personal injury.

WARNING:
To avoid serious personal injury, always tighten the miter lock knob and the bevel lock knob before making a cut. Failure to do so could result in movement of the control arm or miter table while making a cut.

WARNING:
To avoid serious personal injury, keep hands outside the no hands zone, at least 4 in. (100 mm) from the blade. Never perform any cutting operation freehand (without holding workpiece against the fence). The blade could grab the workpiece if it slips or twists.

NOTICE:
Do not start the compound miter saw without checking for interference between the blade, the partial sliding miter fence, and the miter fence. Damage could result to the blade if it strikes the miter fence during operation of the saw.

CUTTING WITH YOUR UNIT

WARNING:
When using a work clamp or C-clamp to secure your workpiece, clamp workpiece on one side of the blade only. The workpiece must remain free on one side of the blade to prevent the blade from binding in workpiece. The workpiece binding the blade will cause motor stalling and kickback. This situation could cause an accident resulting in possible serious personal injury.

WARNING:
NEVER move the workpiece or make adjustment to any cutting angle while the saw is running and the blade is rotating. Any slip can result in contact with the blade causing serious personal injury.

TO MITER CUT/CROSS CUT

See Figures 25 - 26.
A cross cut is made by cutting across the grain of the workpiece. A straight cross cut is made with the miter table set at the 0° position. Miter cross cuts are made with the miter table set at some angle other than zero.

NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Pull out the lock pin and lift saw arm to its full height.
• Loosen the miter lock knob approximately one-half turn and press the detent release button.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale.
• Release the detent release button, then tighten the miter lock knob to secure the miter table.
  NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, and 45° left or right by releasing the detent release button as you rotate the control arm. The control arm will seat itself in one of the positive stop notches, located in the miter table base.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See figures 32 - 33.
  
  
• When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 30.
  
• Grasp the workpiece firmly with one hand and secure it against the fence. Use the work clamp, C-clamp or other suitable clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.
• Grasp the saw handle firmly. Depress the trigger lockout lever and squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the blade to stop rotating before raising the blade out of the workpiece. Wait until the blade stops turning before removing the workpiece from the miter table.

TO BEVEL CUT

See Figure 27.
A bevel cut is made by cutting across the grain of the workpiece with the blade angled to the workpiece. A straight bevel cut is made with the miter table set at the zero degree position and the blade set at an angle between 0° and 45°.

NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Pull out the lock pin and lift saw arm to its full height.
• Loosen the miter lock knob approximately one-half turn and press the detent release button.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale.
• Release the detent release button, then tighten the miter lock knob to secure the miter table.
  NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, and 45° left or right by releasing the detent release button as you rotate the control arm. The control arm will seat itself in one of the positive stop notches, located in the miter table base.
• Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.
• Bevel angles can be set from 0° to 45°.
• Align the indicator point for the desired angle.
• Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See figures 32 - 33.
• When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 30.
• Grasp the workpiece firmly with one hand and secure it against the fence. Use the work clamp, C-clamp or other suitable clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.
• Grasp the saw handle firmly. Depress the trigger lockout lever and squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until the blade stops turning before removing the workpiece from miter table.

TO COMPOUND MITER CUT

See Figures 28 - 29.
A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuts.
To make this type of cut the control arm on the miter table must be rotated to the correct angle and the saw arm must be tilted to the correct bevel angle. Care should always be taken when making compound miter setups due to the interaction of the two angle settings.
Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting.
It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.

NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Pull out the lock pin and lift saw arm to its full height.
• Loosen the miter lock knob approximately one-half turn and press the detent release button.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale.
• Release the detent release button, then tighten the miter lock knob to secure the miter table.
  NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, and 45° left or right by releasing the detent release button as you rotate the control arm. The control arm will seat itself in one of the positive stop notches, located in the miter table base.
• Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.
• Bevel angles can be set from 0° to 45°.
• Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob.
• Recheck miter angle setting. Make a test cut in scrap material.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See figures 32 - 33.
• When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 30.
• Grasp the stock firmly with one hand and secure it against the fence. Use the work clamp, C-clamp or other suitable clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.
• Grasp the saw handle firmly. Depress the trigger lockout lever and squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until the blade stops turning before removing the workpiece from miter table.

TO SUPPORT LONG WORKPIECES

See Figure 30.
Long workpieces need extra supports. Supports, roller stand, or work surface level with the saw table should be placed along the workpiece so it does not sag. The support should let the workpiece lay flat on the base of the saw and work table during the cutting operation. Use the work clamp, C-clamp, or other suitable clamp to secure the workpiece when possible.

CUTTING COMPOUND MITERS

To aid in making the correct settings, the compound angle setting chart below has been provided. Since compound cuts are the most difficult to accurately obtain, trial cuts should be made in scrap material, and much thought and planning made, prior to making the required cut.

COMPOUND-ANGLE SETTINGS FOR POPULAR STRUCTURES
Each B (Bevel) and M (Miter) Setting is Given to the Closest 0.005°

CUTTING CROWN MOLDING

This compound miter saw does an excellent job of cutting crown molding. In general, compound miter saws do a better job of cutting crown molding than any other tool made.

In order to fit properly, crown molding must be compound mitered with extreme accuracy.

The two contact surfaces on a piece of crown molding that fit flat against the ceiling and the wall of a room are at angles that, when added together, equal exactly 90°. Most crown molding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom rear angle (the section that fits flat against the wall) of 38°.

LAYING MOLDING FLAT ON THE MITER TABLE

See Figure 31.
To use this method for accurately cutting crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat on the miter table and against the fence.
When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one angle changes the other angle as well.
Keep in mind that the angles for crown molding are very precise and difficult to set. Since it is very easy for these angles to shift, all settings should first be tested on scrap molding. Also most walls do not have angles of exactly 90°, therefore, you will need to fine tune your settings.
When cutting crown molding by this method the bevel angle should be set at 33.85°. The miter angle should be set at 31.62° either right or left, depending on the desired cut for the application. See the chart for correct angle settings and correct positioning of crown molding on miter table.
The settings in the chart can be used for cutting. All Standard (U.S.) crown molding with 52° and 38° angles. The crown molding is placed flat on the miter table using the compound features of the miter saw.

Bevel Angle Setting	Type of Cut
33.85°	Left side, inside corner Top edge of molding against fence Miter table set right 31.62° Save left end of cut
33.85°	Right side, inside corner Bottom edge of molding against fence Miter table set left 31.62° Save left end of cut
33.85°	Left side, outside corner Bottom edge of molding against fence Miter table set left 31.62° Save right end of cut
33.85°	Right side, outside corner Top edge of molding against fence Miter table set right 31.62° Save right end of cut

CUTTING WARPED MATERIAL

See Figures 32 - 33.
When cutting warped material, always make sure it is positioned on the miter table with the convex side against the fence as shown in figure 32.
If the warped material is positioned the wrong way as shown in figure 33, it will pinch the blade near the completion of the cut.

WARNING:
To avoid a kickback and to avoid serious personal injury, never position the concave edge of bowed or warped material against the fence.

ADJUSTMENTS

WARNING:
Before performing any adjustment, make sure the tool is unplugged from the power supply. Failure to heed this warning could result in serious personal injury.

The compound miter saw has been adjusted at the factory for making accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear. After unpacking the saw, check the following adjustments before you begin using the saw. Make any readjustments that are necessary and periodically check the parts alignment to make sure that the saw is cutting accurately.

PIVOT ADJUSTMENTS

NOTE: These adjustments were made at the factory and normally do not require readjustment.

TRAVEL PIVOT ADJUSTMENT

• The saw arm should rise completely to the up position by itself.
• If the saw arm does not raise by itself or if there is play in the pivot joints, have saw repaired at your nearest authorized service center.

BEVEL PIVOT ADJUSTMENT

• The compound miter saw should bevel easily by loosening the bevel lock knob and tilting the saw arm to the left.
• If movement is tight or if there is play in the pivot, have saw repaired by at your nearest authorized service center.

POSITIVE STOP ADJUSTMENTS

See Figure 34.

NOTE: These adjustments were made at the factory and normally do not require readjustment.

To adjust:

• Unplug the saw.
• Loosen the bevel lock knob by turning the knob counterclockwise.
• Square the blade to the miter table as described in theAssembly section of this manual.
• If the blade is out of square, secure the lock nut in place and loosen or tighten the positive stop adjustment screw using the blade wrench provided.
• Retighten bevel lock knob. Recheck blade-to-table alignment.
  NOTE: The above procedure can be used to check blade squareness of the saw blade to the miter table at both 0° and 45° angles.

The saw has two scale indicators, one on the bevel scale and one on the miter scale. After squaring adjustments have been made, it may be necessary to loosen the indicator screws and reset them to zero. See figures 20 - 21.

MAINTENANCE

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:
Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which can result in serious personal injury.

Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

BRUSH REPLACEMENT

See Figure 35.
The saw has externally accessible brush assemblies that should be periodically checked for wear.

Proceed as follows when replacement is required:

• Unplug the saw.
• Remove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap.
• Remove brush assembly.
• Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other.
• Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.
• Make sure brush cap is oriented correctly (straight) and replace.
• Tighten brush cap securely. Do not overtighten.
