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 lighted. Do not use electrically powered tools 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. 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 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.
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 for better and safer performance. Follow instructions
for changing accessories. Inspect tool periodically and if any part appears broken or damaged,
have it repaired by an authorized technician. The handles must be kept clean, dry, and free
from oil and grease at all times.
10. Disconnect power. Disconnect tool from air compressor when not in use and before changing
accessories, maintaining, repairing, or cleaning.
11. Remove adjusting keys and wrenches. Check that adjusting wrenches are removed from

not in use and before connecting to this tool. Do not carry any tool with your nger on the
trigger, whether it is connected or not.
13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you
are tired.
14. Take caution as some woods contain preservatives such as copper chromium arsenate
(CCA) which can be toxic. When cutting these materials extra care should be taken to avoid
inhalation and minimize skin contact.
15. Check for damaged parts. Before using any tool, any part that appears damaged should be
carefully checked to determine that it will operate properly and perform its intended function.
Check for alignment and binding of moving parts; any broken parts; and any other condition
that may affect proper operation. Any part that is damaged should be properly repaired or
replaced by a qualied technician. Do not use the tool if the trigger does not operate properly.
16. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerator enclosures.
17. Replacement parts and accessories. When servicing, use only identical replacement parts.
Use of any other parts will void the warranty. Only use accessories intended for use with this
tool. All accessories used must be rated 18,000 RPM or greater. Before each use, inspect
the accessory for damage or excess wear. Never use a damage or worn out accessory.
18. Do not operate tool if under the inuence of alcohol or drugs. Read warning labels on
prescriptions to determine if your judgment or reexes are impaired while taking drugs. If there
is any doubt, do not operate the tool.
19. Use proper size and type extension cord. If an extension cord is required for the compressor,
it must be of the proper size and type to supply the correct current to the tool without heating
up. Otherwise, the extension cord could melt and catch re, or cause electrical damage to the
tool.
20. Maintenance. For your safety, service and maintenance should be performed regularly by a
qualied technician.
21. Use clean, dry, regulated, compressed air at 90 PSI. Do not exceed the recommended
90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled gas as
a power source for this tool.
22. This tool has no safety shield. DO NOT USE GRINDING DISCS, GRINDING WHEELS OR
CUT-OFF WHEELS WITH THIS TOOL.
Note: Performance of the compressor powering this tool (if powered by line voltage) may vary
depending on variations in local line voltage. Extension cord usage may also affect compressor
performance.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction 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.)
