3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or

break down, grounding provides a low resistance path to carry electricity away from the user.

5. Double insulated tools are equipped with 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 a polarized outlet. Do not change the plug in any way. Double insulation

6. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.

eliminates the need for the

7. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk of electric shock.

9. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These extension cords are rated for outdoor use, and

reduce the risk of electric shock.

PERSONAL SAFETY

10. Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operat-

ing power tools may result in serious personal injury.

11. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

12. Avoid accidental starting. Be sure the Power Switch is off before plugging in. Carrying power tools with your finger on the Power Switch, or plugging in power tools with the Power Switch on, invites accidents.

13. Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in personal injury.

14. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the power tool in unexpected situations.

15. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat or hearing protection must be used for appropriate conditions

TOOL USE AND CARE

16. Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand is unstable and may lead to loss of

control. Only work on a workpiece that is properly secured.

17. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

18. Do not use the power tool if the Power Switch does not turn it on or off. Any tool that cannot be controlled with the Power Switch is dangerous and must be replaced.

19. Disconnect the Power Cord Plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

20. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

21. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with a sharp cutting edge are less likely to bind and are easier to control. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

22. Check for misalignment or binding of guards and other moving parts,

breakage of parts, cracking or breakage of the Saw Blade, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

23. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous

when used on another tool.

SERVICE

24. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

SPECIFIC SAFETY RULES

1. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. Do not use the Miter Saw in areas near flammable chemicals, dusts, and vapors. Do not use this product in a damp or wet location.

2. Maintain labels and nameplates on the Miter Saw. These carry impor tant information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

3. Do not force the equipment. This Miter Saw will do the work better and safer at the speed and capacity for which it was designed.

4. Keep all guards in place and in working order.

5. Remove all adjusting wrenches from the Miter Saw before turning it on.

6. Do not abuse the Power Cord. Do not use the Power Cord to pull its Plug from an electrical outlet. Keep the Power Cord away from heat, oil, sharp edges, and moving parts. Route the Power Cord safely. Protect the Power Cord from being damaged by other equipment in the work area. Do not route the Power Cord where it can be walked on or tripped over. Replace a damaged Power Cord immediately.

7. Do not use this Miter Saw for cutting metals or brittle materials. Do not cut dangerous materials, such as asbestos which can cause harmful dust or vapors.

8. To avoid accidental injury, always wear heavy duty work gloves when

changing a Saw Blade.

9. Before using the Miter Saw, make sure the Saw Blade is properly mounted on the Saw Spindle. Make sure the Saw Blade is balanced, and is not cracked

or bent.

10. The Saw Blade will become hot while cutting. Allow the Saw Blade to com- pletely cool before touching.

11. Make sure the workpiece is free from nails and any other foreign objects

which can damage the Saw Blade.

12. Keep your body positioned to either side of the Saw Blade, but not in line with the Saw Blade. “Kickback” can cause the Saw to jump backwards.

13. Causes and operator prevention of “kickback”: Kickback is a sudden reaction to a pinched, bound, or misaligned Saw Blade, causing an uncontrolled Saw to lift up and out of the workpiece toward the operator. When the Saw Blade is pinched or bound tightly by the kerf closing down, the Saw Blade stalls and the Motor

reaction drives the tool rapidly toward the operator. If the Saw Blade becomes twisted or misaligned in the cut, the teeth at the back edge of the Saw Blade can dig into the top surface of the workpiece, causing the Saw Blade to climb out of the kerf and jump toward the operator. Kickback is a result of tool misuse and/

or incorrect operating procedures or conditions and can be minimized by taking proper precautions as given below:

A. Maintain a firm grip with both hands on the Saw, and position your body

and arm to allow you to resist kickback forces.

B. When the Saw Blade is binding, or when interrupting a cut for any rea-

son, release the Power Switch and hold the Saw motionless in the workpiece until the Saw Blade comes to a complete stop. Never attempt to

remove the Saw from the workpiece or pull the Saw backward while the Saw Blade is in motion or kickback can occur.

C. When restarting the Saw in the workpiece, center the Saw Blade in the

kerf and check that the saw teeth are not engaged into the workpiece. If

the Saw Blade is binding, it may walk up or kickback from the workpiece as the Saw is restarted.

D. Support large panels to minimize the risk of Saw Blade pinching and

kickback. Large panels tend to sag under their own weight. Supports must

be placed under the panel on both sides, near the line of cut and near the edge of the panel.

E. Do not use a dull or damaged Saw Blade. Unsharpened or improperly set

Saw Blades produce a narrow kerf causing excessive friction, Saw Blade binding and kickback.

F. Make sure all Saw adjustments are tight and secure before making a cut.

If Saw adjustments shift while cutting, it may cause binding and kickback.

18. The Laser on the Miter Saw is rated as a Laser beam. A hazard may exist if you deliberately stare into the beam. Never

aim the Laser beam at any person, animal, or an object other than the workpiece.

19. Make sure the Laser beam is aimed at a sturdy workpiece without reflective surfaces. Reflective surfaces are not suitable for Laser applications, as the

reflective surface may direct the Laser beam back at the operator, causing potential eye damage.

20. Do not attempt to alter the Laser or replace it with a different type. Doing so may result in hazardous radiation exposure.

21. Never attempt to remove material stuck in the moving parts of the Miter

Saw while the machine is plugged in and running.

The operator must understand that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

GROUNDING

WARNING!

Improperly connecting the grounding wire can result in the risk of electric

shock. 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

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 Figure A.)

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 Figure A.)
