Ryobi PBT01B - SLIDING COMPOUND MITER SAW Manual

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.

ADDITIONAL SAFETY RULES

• 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.

The compound miter saw should be mounted to a firm supporting surface such as a workbench, mounting board, or miter saw stand. The saw base has four mounting holes. If using bolts, they should be of sufficient length to accommodate the saw base, lock washers, hex nuts, and the thickness of the workbench or other mounting surface. Tighten all bolts or screws securely.
The hole pattern for mounting to a workbench is shown in figure 7. Carefully check the workbench after mounting to make sure that no movement can occur during use. If any tipping, sliding, or walking is noted, secure the workbench to the floor before operating.

USING THE DEPTH STOP
See Figure 8.

When used, the depth stop limits the downward travel of the blade when cutting dadoes and other non-through cuts.

To use the depth stop:

• Remove the battery.
• If the saw is in storage or transport position, unlock the saw arm.
• Rotate the depth stop away from the motor housing.
• With the end of the depth control knob touching the depth stop, adjust the depth control knob by turning the knob until the desired depth of cut is attained.
• A wooden spacer of at least 2-1/2 inches must be placed between the workpiece and the fence for a consistent depth of cut in the workpiece. Use the work clamp to clamp the spacer and another suitable clamp to clamp the workpiece. Make the slide cut at the desired depth. See Figures 34 - 35.
• Rotate the depth stop back towards the motor housing for normal through cuts.
  NOTE: The depth stop must be moved toward the motor housing before locking/unlocking the saw arm.

LOCKING/UNLOCKING THE SAW ARM

BLADE WRENCH
See Figure 10.
A blade wrench is included with this saw. One end of the wrench is a phillips screwdriver and the other end is a hex key. Use the hex key end when installing or removing blade and the phillips end when removing or loosening screws. A storage area for the blade wrench is located on the back of the left miter fence.

WORK CLAMP
See Figure 11.


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.
The work clamp provides greater control by clamping the workpiece to the fence or the saw table. 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 prior to making the cut.

To install the work clamp:

• Place the work clamp shaft in one of the holes located behind the miter fence.
• Rotate the work clamp knob to move it up or down as needed to secure the workpiece.

SIDE HANDLES
See Figures 12 - 13.
Side handles have been provided for both the left and the right side of the saw.

To install side handles:

• Align the holes in one of the side handles with the holes in the saw base.
• Insert the provided hex screws into the holes and tighten securely using the blade wrench provided.
• Repeat for other side handle.

TO INSTALL/REPLACE THE BLADE
See Figures 14 - 15.
The blade is shipped installed on this miter saw model. Instructions have been included for reference when changing or replacing blades.

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.

• Remove the battery.
• Raise the saw arm.
• Rotate lower blade guard up and back to expose the blade bolt.
• Depress the spindle lock button and rotate the blade bolt until the spindle locks.
• Using the blade wrench provided, loosen and remove the blade bolt.
  NOTE: The blade bolt has left hand threads. Turn blade bolt clockwise to loosen.
• Remove the outer blade washer.
  NOTE: The inner blade washer is integrated into the spindle and cannot be removed.
• Wipe a drop of oil onto inner blade washer 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 15.
• Replace the outer blade washer. Double "D" flats on blade washers align with flats on spindle.
• Depress spindle lock button and replace blade bolt.
  NOTE: The blade bolt has left hand threads. Turn blade bolt counterclockwise to tighten.

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 upper blade guard functions correctly.

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 16.


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.
Never operate the saw without a throat plate installed.

To remove/replace:

• Remove the battery.
• Remove the screws securing the throat plate.
• Lift the throat plate from the saw.
• To reinstall the throat plate, align the holes in the throat plate with the holes in the saw base.
• Retighten the screws, being careful not to overtighten which can cause the throat plate to bow or bend.

ADJUSTING SUPPORT FOOT
See Figure 16.
Turn the support foot clockwise or counterclockwise depending on the amount of support needed for making sliding cuts.
NOTE: Many of the illustrations in this manual show only portions of the compound miter saw. This is intentional so that we can clearly show points being made in the illustrations. Never operate the saw without all guards securely in place and in good operating condition.

Always remove battery pack from your tool when you are assembling parts, making adjustments, cleaning, transporting, or when not in use. Removing battery pack will prevent accidental starting that could cause serious personal injury.

• Locate and depress the latches on each side of the battery pack to release the battery pack from the saw.
• Remove the battery pack.

For complete charging instructions, refer to the Operator's Manuals for your battery pack and charger.

CUTTING WITH YOUR COMPOUND MITER SAW

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.

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.

Do not try to cut narrow pieces using the sliding feature. Failure to heed this warning could result in serious personal injury.

TO MAKE NON-SLIDING CUTS

Securely tighten the slide lock knob when making any non-sliding cuts. Failure to tighten the knob could result in the saw head moving during the cutting operation.

TO MITER CUT/CROSS CUT
See Figures 27 - 28.
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 0°.
NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Slide the saw head to its most rearward position and tighten the slide lock knob securely.
• Raise saw arm to its full height.
• Loosen the miter lock handle approximately one-half turn and squeeze the detent release lever.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale.
• Release the detent release lever, then tighten the miter lock knob to secure the miter table.
  NOTE: You can quickly locate 0°, 15°, 22-1/2°, 31.6°, and 45° left or right by releasing the detent release lever 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 41 - 42.
• 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 32.
• Lower the blade and align the cutting line on the workpiece with the edge of saw blade or the blade shadow.
• Grasp the stock firmly with one hand and secure it against the fence. Use the work clamp or a C-clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation 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 workpiece and removing the workpiece from the miter table.

TO BEVEL CUT
See Figure 29.
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.

• Slide the saw head to its most rearward position and tighten the slide lock knob securely.
• Pull out the lock pin and lift saw arm to its full height.
• Loosen the miter lock handle approximately one-half turn and squeeze the detent release lever.
• Rotate the control arm until the scale indicator is positioned at 0°.
• Release the detent release lever, engaging the positive stop notch, then tighten the miter lock knob to secure the miter table.
  NOTE: You can quickly locate 0°, 15°, 22-1/2°, 31.6°, and 45° left or right by releasing the detent release lever 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 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 40 - 41.
• 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 32.
• Lower the blade and align the cutting line on the workpiece with the edge of saw blade or the blade shadow.
• Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-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 workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table.

TO COMPOUND MITER CUT
See Figures 30 - 31.
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.

• Slide the saw head to its most rearward position and tighten the slide lock knob securely.
• Pull out the lock pin and lift saw arm to its full height.
• Loosen the miter lock handle approximately one-half turn and squeeze the detent release lever.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale.
• Release the detent release lever, then tighten the miter lock knob to secure the miter table.
• 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 could collapse on the blade at the end of the cut, jamming the blade. See Figures 40 - 41.
• 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 32.
• Lower the blade and align the cutting line on the workpiece with the edge of saw blade or the blade shadow.
• Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-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 workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table.

TO SUPPORT LONG WORKPIECES
See Figure 32.
Long workpieces need extra supports. Supports 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 optional work clamp or a C-clamp to secure the workpiece.


Never make a cut by pulling the saw toward you as the blade can climb on top of the workpiece and come toward you. Failure to heed this warning could result in serious personal injury.

TO SLIDE CUT
See Figures 33 - 34.
The sliding feature will cut workpieces up to 1-1/2 in. thick and 9-1/4 in. wide. With the saw off, pull the saw arm forward. Turn the saw on (let blade reach maximum speed), push the blade down cutting into the workpiece then back toward the rear of the saw to make a cut. Cuts are made by pushing the saw blade away from you and toward the bevel scale at the back of the saw stopping when the full rear position has been reached after each cut. When the saw is running (turned on), NEVER pull the saw blade toward you or toward the front of the saw.

• Raise saw arm to its full height.
• 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 41 - 42.
• 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 32.
• Lower the blade and align the cutting line on the workpiece with the edge of saw blade or the blade shadow.
• Loosen the slide lock knob by turning the knob counterclockwise.
• Grasp the stock firmly with one hand and secure it against the fence. Use the work clamp or a C-clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation to make sure that no problems will occur when the cut is made.
• With the saw off, grasp the saw handle firmly then pull the saw forward until the blade arbor (center of the saw blade) is over the front of the workpiece or until the saw is fully extended.
• 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 front edge of the workpiece.
• Push the saw handle away from you and toward the bevel scale at the back of the saw.
• Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece and removing the workpiece from miter table.

NOTE: 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 0°.

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

CUTTING CROWN MOLDING
The 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 36.
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 31.6° either right or left, depending on the desired cut for the application. See the chart below for correct angle settings and correct positioning of crown molding on miter table. The settings in the chart below 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 your 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

NESTING CROWN MOLDING AGAINST THE MITER FENCE
See Figure 37 - 39.
NOTE: This method of cut is for crown molding up to 3-3/8 in. tall, when using an auxiliary fence. Do not attempt to cut molding that is larger than 3-3/8 in. tall.
NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Assemble and attach auxiliary fence as shown in figure 34.
• Loosen the slide lock knob.
• Slide the saw forwards or backwards to align the arrow on the crown indicator with the arrow on the pivot assembly, then tighten the slide lock knob securely.
• Set the bevel angle at 0° and the miter angle at 45° to either the left or the right. (For making 90° corners.)
• Nest and secure the crown molding against auxiliary fence using a spring clamp and hold crown molding securely.
• Before turning on the saw, perform a dry run of the cutting operation 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 crown molding.

VERTICALLY CUTTING BASE MOLDING AGAINST THE MITER FENCE
See Figure 40.
NOTE: It may be necessary to adjust the partial sliding miter fence to ensure proper clearance prior to making the cut.

• Set the bevel angle at 0° and the miter angle at 45° to either the left or the right. (For making 90° corners.)
• Place and secure the base molding vertically against the fence using a spring clamp and hold the base molding securely.
  NOTE: To avoid interference between the base molding and the motor, the molding should be placed no more than a half-inch over the throat plate when cutting or trimming base molding at 45° right miter angles.
• Before turning on the saw, perform a dry run of the cutting operation 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 base molding.

CUTTING WARPED MATERIAL
See Figures 41 - 42.
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 41.
If the warped material is positioned the wrong way as shown in figure 42, it will pinch the blade near the completion of the cut.

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



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

CLAMPING WIDE WORKPIECES
See Figure 43.
When cutting wide workpieces, such as nominal 2 in. x 6 in., boards should be clamped with a work clamp as shown in figure 43.

ADJUSTMENTS

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 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.

TO ADJUST THE BEVEL PIVOT

• The compound miter saw should bevel easily by loosening the bevel lock knob and tilting the saw.
• If movement is tight or if there is play in the pivot, have saw repaired at your nearest AUTHORIZED SERVICE CENTER.

POSITIVE STOP ADJUSTMENTS
See Figure 44.
NOTE: These adjustments were made at the factory and normally do not require readjustment.

To adjust:

• Remove the battery.
• Loosen the bevel lock knob by turning the knob counterclockwise.
• Square the blade to the miter table as described in the Assembly 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.

Your saw has several scale indicators. 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

When servicing, use only identical replacement parts. Use of any other part can create a hazard or cause product damage.

Always wear eye protection with side shields marked to comply with ANSI Z87.1 during product operation. If operation is dusty, also wear a dust mask.

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.

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, carbon dust, etc.

Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken, or destroy plastic.
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.
