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 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 and nonskid 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 filings or wood chips. Wear an
ANSI approved dust mask or respirator when working around metal, wood, and
chemical dusts and mists. Other people in the work area must also wear ANSI
approved impact safety goggles.

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. Do not operate a tool if any
portion of the tool’s operating controls are inoperable, disconnected, altered or not working
properly.

10. Disconnect air supply. Disconnect air hose when adding nails, during maintenance, and
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 attaching to an air source.

12. Avoid unintentional starting. Be sure the trigger is in the Off position when not in use and
before plugging in. Do not carry any tool with your finger on the trigger, whether it is attached
to an air source or not. Do not point the tool towards yourself or anyone whether it contains
fasteners or not.

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
properly repaired or replaced by a qualified technician. Do not use the tool if any the trigger
does not operate properly.

15. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerator enclosures.

16. 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.

17. 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.

18. Use proper size and type extension cord. If an extension cord is required, 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
tool. Check your air compressor’s manual for the appropriate size cord.

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

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

21. Do not load nails with the trigger or safety depressed. Unintentional firing may

occur. Do not load nails when the air hose is connected to the tool. Always assume
that the tool contains fasteners.

22. Fire fasteners into an appropriate work surface only. Do not attempt to fire
fasteners into surfaces too hard to penetrate. Do not drive fasteners on top of other
fasteners, or at too steep of an angle. Fasteners can ricochet causing personal injury.

23. Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.

24. Disconnect air supply before loading Nailer. Before reloading (or making any
adjustments) to the Nailer make sure that the compressed air is disconnected.

25. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When stapling or nailing these materials extra
care should be taken to avoid inhalation and minimize skin contact.

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

(California Health & Safety Code § 25249.5,

et seq.

)

26. Stay within air pressure capacity. Never operate the Nailer above 125 PSI.

27. Hold tool away from head and body. During operation the Nailer may kick back causing
injury.

28. Transport Nailer safely. Always disconnect air supply when moving the tool in the
workplace. Carry the tool by the handle and avoid contact with the trigger.

Note: Performance of the compressor (if powered by line voltage) may vary depending on

variations in local line voltage. Extension cord usage may also affect tool
performance.

Warning: The warnings, cautions, 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.
