IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings

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 mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
   1. Keep work area clean and well lit.
      Cluttered or dark areas invite accidents.
   2. 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.
   3. Keep children and bystanders away while operating a power tool.
      Distractions can cause you to lose control.

2. Electrical safety
   1. 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.
   2. 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.
   3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   4. 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.
   5. 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.
   6. 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.

3. Personal safety
   1. 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.
   2. 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.
   3. 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 energizing power tools that have the switch on invites accidents.
   4. 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.
   5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
   7. 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.
   8. 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.
   9. Only use safety equipment that has been approved by an appropriate standards agency. Unapproved safety equipment may not provide adequate protection. Eye protection must be ANSI-approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.
   10. Avoid unintentional starting. Prepare to begin work before turning on the tool.
   11. Do not leave the tool unattended when it is plugged into an electrical outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.
   12. This product is not a toy.
       Keep it out of reach of children.
   13. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should:
       • Avoid operating alone.
       • Do not use with Trigger locked on.
       • Properly maintain and inspect to avoid electrical shock.
       • Properly ground power cord. Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock.
   14. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

4. Power tool use and care
   1. 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.
   2. 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.
   3. 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.
   4. 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.
   5. 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.
   6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   7. 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.
   8. 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.

5. Service
   1. 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.
   2. Maintain labels and nameplates on the tool. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

6. Safety instructions for mitre saws
   1. Mitre 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.
   2. 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.
   3. 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.
   4. Push the saw through the workpiece. Do not pull the saw through the workpiece. To make a cut, raise the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head down and push the saw through the workpiece. Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece and violently throw the blade assembly towards the operator.
   5. 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.
   6. 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.
   7. 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.
   8. 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.
   9. 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.
   10. Ensure the mitre saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduces the risk of the mitre saw becoming unstable.
   11. Plan your work. Every time you change the bevel or mitre 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.
   12. 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 mitre 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.
   13. 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.
   14. 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 them blade and thrown violently.
   15. 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.
   16. Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.
   17. If the workpiece or blade becomes jammed, turn the mitre 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 .mitre saw.
   18. 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.
   19. 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 cause the saw head to be suddenly pulled downward, causing a risk of injury.

7. Vibration Safety
   This tool vibrates during use.
   Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders.
   To reduce the risk of vibration-related injury:
   1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-ups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud's Disease should not use this tool. If you feel any symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.
   2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.
   3. Wear suitable gloves to reduce the vibration effects on the user.
   4. Use tools with the lowest vibration when there is a choice.
   5. Include vibration-free periods each day of work.
   6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
   7. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use immediately.

Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Grounded Tools: Tools with Three Prong Plugs

3-Prong Plug and Outlet

1. Tools marked with "Grounding Required" have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding system and must never be attached to an electrically "live" terminal. (See 3-Prong Plug and Outlet.)
3. The tool must be plugged into an appropriate outlet, properly installed and grounded in accordanc with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong Plug and Outlet.)

Double Insulated Tools: Tools with Two Prong Plugs

Outlets for 2-Prong Plug

1. Tools marked "Double Insulated" do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Outlets for 2-Prong Plug.)

Extension Cords

1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)
4. When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.)
5. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix "W-A" ("W" in Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

Setting and Testing

TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Make sure that the Trigger is in the off-position and unplug the tool from its electrical outlet before performing any procedure in this section.

Adjusting the Miter Angle

Figure E

A miter cut is one that is at an angle across the horizontal surface of the material. 45º miter cuts to join two pieces in a right angle corner are common. A 30º cut is often used for a scarf joint or to make a chamfered end.

1. Pull up on the Miter Lock Handle to unlock the Table. Push down on the Miter Latch Lever and move the Table to the desired angle.
2. The Miter Angle Indicator will indicate the selected angle. When the Miter Latch Lever is released, the Table will lock into place at often used miter angles, including 0º, 15º, 22.5º, 31.6º, and 45º left and 0º, 15º, 22.5º, 31.6º, 45º, and 60º right.
3. To override the pre-set detents (stops) for micro adjustments at any angle, push down and hold the Miter Latch Lever and push in on the Detent Latch Button to latch in place. Release the Miter Latch Lever and adjust Table to any position on the miter scale. To disengage push down on the Miter Latch Lever to release the Detent Latch Button.
4. Push down on the Miter Lock Handle to lock the Table after adjusting the miter angle.
5. With the Table adjusted to the desired angle, place the workpiece flush against the Fence, secure it with the Clamp and make the cut.

Adjusting the Bevel Angle

Figure F

A bevel cut is one that is at an angle vertically. Bevel cuts can be used to miter relatively wide and thin material. Bevel cuts can be used in combination with a miter cut to form a compound angle. Compound angle cuts are often used in crown moldings, picture frames and similar trim materials.

1. Pull up on the Bevel Lock Handle to unlock the Saw Head Assembly.
2. To adjust the left bevel angle, move the Saw Head Assembly to the left to the desired angle. Read the angle on the Bevel Scale. To adjust the right bevel angle, pull out the Bevel Angle Lock Button at the rear of the Saw and move the Saw Head Assembly to the right to the desired angle.
3. Lock the Saw Head Assembly into position by pushing down on the Bevel Lock Handle.
4. Make a sample cut in a piece of scrap to confirm that the bevel angle is correct.
   If it is not, correct the angle before cutting.

TO PREVENT SERIOUS INJURY:
Adjust both sides of the Fence clear of the Blade's cutting path after making any adjustment to the cutting angle. Move the Blade through its full range of motion to ensure the Fences are clear.

Aligning the Fence

1. After adjusting the miter, bevel, or depth setting, check and adjust both sides of the Fence.
2. Loosen one of the Fence Lock Knobs, and move its Sliding Fence to be within 1/8" of the blade.
3. Tighten the Fence Lock Knob. Make sure that the Sliding Fence still does not contact the Blade.
4. Repeat the process for the other Fence Lock Knob and Sliding Fence.

Using the Depth Stop

Figure G

If a kerfing or rabbet cut which does not cut through the workpiece is desired, use the Depth Stop to control the depth of the cut.

1. Pull out the Head Lock-Down Pin and raise the Saw Head Assembly.
2. Rotate the Depth Stop down to a horizontal position to use the Depth Adjustment Bolt setting.
3. Pull down on the Saw Head to check the current setting.
4. To change the setting, first loosen the Lock Nut on the Depth Adjustment Bolt. Turn the Depth Adjustment Bolt clockwise to decrease depth and counterclockwise to increase depth. Tighten the Lock Nut after adjustment
5. To disengage, rotate the Depth Stop up to its vertical position.

Kerf Board Replacement / Adjustment

If the Kerf Boards become damaged they must be replaced.

1. Remove the six screws holding the two Kerf Boards in place and lift them from the Saw.
2. Install the new Kerf Boards, placing them on either side of the cut line. Replace the six screws and tighten them slightly.

To adjust the Kerf Boards:

Figure H

1. Lower the Saw Head Assembly and lock it down with the Head Lock-Down Pin.
2. Check for blade clearance by moving the Saw Head through its full range of motion with the bevel angle set at 0º, at maximum left bevel angle, and at maximum right bevel angle. Refer to Adjusting the Bevel Angle.
3. If the Saw Blade hits either of the Kerf Boards, loosen the three screws for that Board and adjust. Tighten the screws and check again for blade clearance.
4. After verifying blade clearance, tighten the six screws holding the Kerf Boards in place.

Workpiece Set Up

1. Secure loose workpieces using a vise or clamps (not included) to prevent movement while working.
2. Cut only the following materials:
   Dimensional lumber, plywood, particle board, plastic.
   Note: Use caution to avoid overheating the cutting tips. If cutting plastic, cut at an even pace to avoid melting it.
3. Refer to cutting capacities in the Specifications Table for limitations on workpiece size.
4. Allow room on both left and right sides of Saw for extended workpieces.
5. Use additional supports if needed to ensure the stability of the workpiece. Mount the Saw so that the surface is level to the ground, and additional supports to provide a surface on the same level as the saw table. If the work surface and any workpiece supports are not level, and on the same level, unwanted bevel angles will appear in the cuts resulting in poor joinery.
6. Secure workpieces to the saw table using the Clamp or other clamping devices (not included). Securing the workpiece will provide safety by preventing kick back and by removing the need to hold workpieces near the blade by hand. Clamping the workpiece will also improve cutting accuracy by preventing the workpiece from moving during the cutting operation.

Using the Workpiece Extension Supports

1. The Table Extensions are located on each side of the Table, and locked in place using the Table Extension Lock Levers.
2. When properly installed, the upper face of the Table Extensions are level with the Table, and provide a wider support surface for the workpiece. Each Extension has a Cut Stop Lever which can be raised to make repetitive cuts.
3. Support the workpiece to be level with the table, and so that after the cut is made the cut off pieces will not fall. Use sawhorses or other supports (not included) to support longer workpieces.
4. If the workpiece is not level, you will make an unintentional bevel cut in the material. If the workpiece is not supported, it will bind the blade and may cause the material to kick back, potentially causing injury.

General Instructions for Use

1. Make sure that the Trigger is in the off-position, then plug in the tool.
   
   TO PREVENT SERIOUS INJURY:The tool will restart automatically if stalled.

Sliding Miter Saw Cutting Procedure

2. Unlock the Head Lock-Down Pin.
3. Check that all adjustment knobs are tight (Miter Lock Handle, Bevel Lock Handle, Fence Lock Knobs, and Table Extension Lock Levers).
4. Blow any sawdust or debris away from the Fence. Place the work material against the Fence.
5. To use the Shadow Cut Line Guide System to align the cut, turn its Switch on. Pull the Saw Head down until the Saw Blade is close to the workpiece and the Blade's shadow appears on the work material, indicating where the Blade will cut. Align the marked location of the cut on the workpiece with the edge of the Saw Blade shadow.
6. The Saw will also operate without using the Shadow Cut Line Guide System if desired. In that case align the marked location of the cut on the work material with the saw blade. To prevent the workpiece from being cut too short, align the edge of the blade with the measured mark, keeping the rest of the blade on the waste side of the cut.
7. Hold the work material in place using the Clamp. Ensure that the work material is level and supported securely. Use saw horses or supports if necessary.
   
   
   Saws can quickly amputate fingers if misused. Keep hands well clear of cutting area.
8. Grip the Saw Handle, press the Trigger Lock Button with your thumb, and squeeze the Trigger to start the Saw.
9. Use two hands and hold workpiece securely against table and fence at all times.
10. With narrow material, press down lightly to cut the workpiece. Press straight down, "chopping" the material. Do not bear down on the material — use light downward pressure. If the material binds the blade, release the Trigger.
11. With wide material, move the Blade across the workpiece while cutting as follows:
    1. Loosen Slide Lock Knob and pull
    2. Press down on the Saw Handle.
    3. Push the Saw Head toward the rear to make the cut. Refer to Figure I.
       
       Figure I
       
       Do not bear down on the material — use light downward and lateral pressure. If the material binds the blade, release the Trigger.

12. When the cut is completed, raise the Saw Head, release the Trigger, wait for the Blade to stop turning, release the Clamp and remove the workpiece from the Saw.
13. To prevent accidents, turn off the tool and unplug it after use. Clean, then store the tool indoors out of children's reach.
14. Lock the Saw Head down and lock all other adjustments before moving the Saw. Use the Carrying Handle and handle cut outs on each side of the Base to lift and support the Saw while moving it.

Checking and Calibrating the Fence

The Fence holds the workpiece in a fixed position while the Table and/or the Saw Head Assembly are adjusted in a miter or bevel angle.
To make accurate cuts, the Fence must be perpendicular (at a 90º angle) to the Saw Blade.

1. Before beginning work, make a test cut on scrap material with the Table set to the 0º miter position.
2. Check the cut with an accurate square. You can also reverse the two pieces, hold the cut ends together, and hold a good straight edge along the side of the pieces.
3. If either test reveals that the cut is not a true 90º angle, adjust the Fence before beginning work.

If Fence needs adjustment:

1. First unplug the tool.
2. Loosen the Slide Lock Knob and push the Saw Head Assembly to its rearmost position and retighten the Knob.
3. Lower the Saw Head Assembly and lock it in place using the Head Lock-Down Pin.
4. Lay a carpenter's square on the Table with one edge along the Blade and the other along the Fence. Any inaccuracy should be visible.
   NOTE: The square must contact the surface of the blade, not the teeth, for an accurate reading.
   
5. The Fence is held in place with four Fence Adjusting Bolts. Remove both Sliding Fences to access the Bolts. Loosen the Bolts slightly, and gently tap the Fence into position using a soft mallet. Tighten the Bolts and make another test cut. Repeat the process until the Fence is adjusted accurately.
   

Calibrating the Bevel Angle

For making accurate cuts, the Saw Blade must be adjusted to be exactly vertical to the Table.

1. To check the angle, have the Saw Head Assembly in its normal upright position and set to the 0º bevel position. Make a cut on a piece of flat sided, fairly thick scrap material.
2. Check the cut with an accurate square. The cut should be at exactly 90º.
3. Angle can also be checked by rotating one cut-off piece 180º and holding the cut ends together. If the cut is not exactly vertical, the two pieces will form a slight angle.

0° Bevel Angle Adjustment

1. First unplug the tool.
2. Set the Miter Table at 0°.
3. Unlock the Bevel Lock Handle, move the Saw Head Assembly until the Bevel Angle Indicator is at 0° on the Bevel Scale, then lock the Bevel Lock Handle.
4. Pull down the Saw Head until the Blade just enters the table insert.
5. Place a framing square on the Miter Table and up against the Saw Blade. NOTE: The square must contact the surface of the Blade, not the teeth, for an accurate reading.
6. If the Blade is not 90° square with the Miter Table, loosen the 0° Bevel Set Bolt on the saw arm with a hex key (not included).
7. Adjust the saw arm perpendicular to the Miter Table.
8. After alignment is achieved, tighten the 0° Bevel Set Bolt.
   
   TO PREVENT SERIOUS INJURY:
   Adjust both sides of the Fence clear of the Blade's cutting path after making any adjustment to the cutting angle. Move the Blade through its full range of motion to ensure the Fences are clear.

45° Bevel Angle Adjustment

Adjust the 45° bevel angle only after performing the 0° bevel angle adjustment.

9. Remove the Sliding Fences.
10. Unlock the Bevel Lock Handle.
11. If required, pull out the Bevel Angle Lock Button to enable the right bevel angle or bevel angle > 45°.
12. Move the Saw Head until the Bevel Angle Indicator is at left 45° on the Bevel Scale.
13. Pull down the Saw Head until the Blade just enters the table insert.
14. Place a triangle square on the Miter Table and up against the Saw Blade.
15. If the Blade is not 45° with the Miter Table, loosen the Left 45° Bevel Set Bolt on the saw arm with a hex key.
16. Adjust the saw arm 45° to the Miter Table.
17. After alignment is achieved, tighten the Left 45° Bevel Set Bolt.
18. Replace the Sliding Fences.
19. To adjust the right 45° bevel angle, perform the same procedure described above with the following excepttions:
    • Move the Saw Head until the Bevel Angle Indicator is at right 45° on the Bevel Scale.
    • Use the Right 45° Bevel Set Bolt for alignment.

Calibrating the Miter Angle Indicator

Check the accuracy of the Miter Angle Indicator only after checking or adjusting the Fence to confirm that it is at 90º to the Saw Blade.

1. Loosen the Adjustment Screw holding the Miter Angle Indicator in place.
2. Rotate it until the pointer is exactly on 0º.
3. Retighten the Screw.

Troubleshooting

Problem	Possible Causes	Likely Solutions
Tool will not start.	Cord not connected. No power at outlet. Tool's thermal reset breaker tripped (if equipped). Internal damage or wear. (Carbon brushes or Trigger, for example.)	Check that cord is plugged in. Check power at outlet. If outlet is unpowered, turn off tool and check circuit breaker. If breaker is tripped, make sure circuit is right capacity for tool and circuit has no other loads. Turn off tool and allow to cool. Press reset button on tool. Have technician service tool.
Tool operates slowly.	Forcing tool to work too fast. Extension cord too long or cord diameter too small.	Allow tool to work at its own rate. Eliminate use of extension cord. If an extension cord is needed, use one with the proper diameter for its length and load. See Extension Cords in Grounding section.
Performance decreases over time.	Carbon brushes worn or damaged.	Have qualified technician replace brushes.
Excessive noise or rattling.	Internal damage or wear. (Carbon brushes or bearings, for example.)	Have technician service tool.
Overheating.	Forcing tool to work too fast. Blocked motor housing vents. Motor being strained by long or small diameter extension cord.	Allow tool to work at its own rate. Wear ANSI-approved safety goggles and NIOSH-approved dust mask/respirator while blowing dust out of motor using compressed air. Eliminate use of extension cord. If an extension cord is needed, use one with the proper diameter for its length and load. See Extension Cords in Grounding section.
Follow all safety precautions whenever diagnosing or servicing the tool. Disconnect power supply before service.
