Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to reduce the risk
of personal injury and damage to equipment. Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet locations.
Don’t expose to rain. Keep work area well lit. Do not use electrically powered tools such as an air
compressor in the presence of ammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them handle
machines, tools, or extension cords.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust.
Always lock up tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a
larger industrial tool. There are certain applications for which this tool was designed. It will do the job
better and more safely at the rate for which it was intended. Do not modify this tool and do not use
this tool for a purpose for which it was not intended.
6. Dress properly while working. Do not wear loose clothing or jewelry as they can be caught
in moving parts. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
7. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear a full
face shield if you are producing metal lings or wood chips. Wear an ANSI approved dust mask or
respirator when working around metal, wood, and chemical dusts and mists.
WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities, contain chemicals known (to the State of California) to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are: lead from lead-based paints,
crystalline silica from bricks and cement or other masonry products, arsenic and chromium from
chemically treated lumber. Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially designed to lter
out microscopic particles. (California Health & Safety Code § 25249.5, et seq.)

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across
running machines.
9. Maintain tools with care. Keep tools clean and in good condition for better and safer performance.
Follow instructions for lubricating and changing accessories. Inspect tool ttings and hoses
periodically and, if damaged, have them repaired by an authorized technician. The handles must be
kept clean, dry, and free from oil and grease at all times.
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 inuence of drugs, alcohol, or medication. A
moment of inattention while operating power tools may result in serious personal injury.
11. Avoid accidental starting. Be sure the Throttle Lever is in the OFF position before attaching
the air pressure hose. Carrying power tools with your nger on the throttle lever invites accidents.
12. 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.
13. 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.
14. Use clamps (not included) or other practical ways to secure and support the work piece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
15. 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.
16. Disconnect the air hose from the tool before making any adjustments, changing accessories,
or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
17. Check for misalignment or binding of moving parts, breakage of parts, 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.
18. Tool service must be performed only by qualied repair personnel. Service or maintenance
performed by unqualied personnel could result in a risk of injury.
19. When servicing a tool, use only identical replacement parts. Use of unauthorized parts or failure
to follow maintenance instructions may create a risk of electric shock or injury.
20. Maintain labels and nameplates on the tool. These carry important information. If unreadable or
missing, contact Harbor Freight Tools for a replacement.
21. When starting a hand-held power tool, always maintain a rm grip on the tool with both
hands to resist starting torque.
22. Always keep the air pressure hose away from moving parts on the tool.
23. Hold tool by insulated gripping surfaces when performing an operation where the tool may
contact hidden wiring. Contact with a “live” wire will make exposed metal parts of the tool
“live” and shock the operator.
24. Never lay the tool down until the motor has come to a complete stop. The tool may create
unforeseen risk while the motor cycles down.
Warning: The warnings, cautions, and instructions discussed in this instruction manual can-
not 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.
