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 a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Page 2 For technical questions, please call 1-888-866-5797.
Item 57839
2. Electrical safety a. 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.
b. 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.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d. 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.
e. 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.
f. 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 a. 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.
b. 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.
c. 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.
d. 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.
e. Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f. 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.
g. 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.
h. 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.
i. 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.
j. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
k. 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.
l. This product is not a toy.
Keep it out of reach of children.
m. 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.
n. 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 a. 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.
b. 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.
c. 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.
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g. 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.
h. 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 a. 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.
b. 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 a. 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.
b. use clamps to support the workpiece whenever possible. if supporting the workpiece by hand, you must always keep your hand at least 4 inches (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.
c. the workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece
Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
d. 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.
e. Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
f. Do not reach behind the fence with either hand closer than 4 inches (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.
g. 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.
Page 4 For technical questions, please call 1-888-866-5797.
Item 57839
h. 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.
i. 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.
j. 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.
k. 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 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.
l. 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.
m. 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.
n. 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.
o. always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods have a tendency to roll pull the work with your hand into the blade.
p. Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.
q. 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.
r. 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.
s. 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: a. 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.
b. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.
c. Wear suitable gloves to reduce the vibration effects on the user.
d. Use tools with the lowest vibration when there is a choice.
e. Include vibration-free periods each day of work.
f. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
g. 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
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 accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration.
(See 3-prong plug and Outlet.)
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.)
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 3-prong plug and Outlet.)
Page 6 For technical questions, please call 1-888-866-5797.
®
Item 57839
Extension cords
1. Grounded tools require a three wire extension cord.
Double Insulated tools can use either a two or three wire extension cord.
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.
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.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

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 on page 8 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 inserted into each side of the Table, and locked in place using the Table Extension Knobs.
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 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.

2. Make sure all adjustment knobs are tight
(Miter Lock Knob, Bevel Lock Lever,
Fence and Table Extension Knobs).
3. Blow any sawdust or debris away from the Fence.
Place the work material against the Fence.
10. With narrow material, press down lightly to cut the workpiece. Press straight down,
“chopping” the material. Do not bear down on
4. Align the marked location of the cut on the work material with the saw blade.
Note: To prevent your 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.
5. 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.
If the material binds the blade, release the Trigger.
11. With wide material, move the Blade across the workpiece while cutting as follows: a. Loosen Slide Lock Knob and pull
Saw Head Assembly forward. b. Press down on the Saw Handle.

tO prEVENt SEriOuS iNJury FrOM tOOL FaiLurE:
Do not use damaged equipment. if abnormal noise or vibration occurs, have the problem corrected before further use.
cleaning, Maintenance, and Lubrication
1. BEFOrE EacH uSE, inspect the general condition of the tool. Check for:
• loose hardware
• misalignment or binding of moving parts
• cracked or broken parts
• damaged electrical wiring
• any other condition that may affect its safe operation.
2. aFtEr uSE, wipe external surfaces of the tool with clean cloth.
3. Periodically, wear ANSI-approved safety goggles and NIOSH-approved breathing protection and blow dust out of the motor vents using dry compressed air.
4. WarNiNG! tO prEVENt SEriOuS iNJury: if the supply cord of this power tool is damaged, it must be replaced only by a qualified service technician.
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. 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 Miter angle indicator
After checking or adjusting the Fence to confirm that it is at 90º to the Blade, check the accuracy of the Miter
Angle Indicator.
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.
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 with the Bevel Stop
Block in the vertical 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.
WarNiNG! tO prEVENt SEriOuS iNJury: 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.
4. If necessary, the 0° bevel angle can be corrected by loosening the Zero Stop Lock Nut, located to the left of the Bevel Stop Block, and adjusting the Zero Stop Screw. Tighten the Zero Stop
Lock Nut after adjustment and make another test cut. Repeat the process until the
0° bevel angle is adjusted accurately.
