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 tools in damp or wet
locations. Don’t expose to rain. Keep work area well lit. Do not use electrically
powered compressors in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, extension cords, or air hoses.

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 nonconductive clothes (including long pants) and
nonskid protective 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 and
noise dampening devices (i.e. earmuffs, ear plugs). Wear heavy work gloves.

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.

9. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and, if damaged, have them repaired by an authorized technician. The
handle must be kept clean, dry, and free from oil and grease at all times.

10. Disconnect air supply. Disconnect air hose when not in use.

11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.

12. Avoid unintentional starting. Be sure the regulator is in the Off position when not in
use and before plugging in.

13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.

14. 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
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be proper ly repaired or replaced by a qualified
technician. Do not use the tool if regulator does not operate properly.

15. 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.

16. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels if taking prescription medicine to determine if your judgement or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.

17. Use proper size and type extension cord. If an extension cord is required for the air
compressor, it must be of the proper size and type to supply the correct current to the
compressor without heating up. Otherwise, the extension cord could melt and catch
fire, or cause electrical damage to the compressor. Check your air compressor’s
manual for the appropriate size cord.

18. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician.

19. Compressed air only. Never use combustible gas as a power source.

- Arsenic and chromium from chemicall y treated lumber
Your risk from these exposures varies, depending on how often y ou 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 filter out microscopic particles.
