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. Do not 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 non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.

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

8. Use eye and ear protection. Always wear ANSI approved impact safety

goggles and appropriate hearing protection. 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.

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 Hose and release any built-up air pressure. Never service the
Nailer, clear jams, or disassemble with the air hose attached. Always release any
built-up air even after disconnecting hose. Disconnect the Nailer 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 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. This product is to be repaired and serviced
only by a qualified technician. When this product is serviced, only identical
replacement parts should be used. Use of any other parts will void the warranty. Only
use accessories intended for use with this tool. Approved accessories are available

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. It is also possible that the use of an extension cord may cause your circuit

panel fuse to break. If this happens, either use the compres-

adjustments to) the Nailer make sure that the compressed air is disconnected.

23. Fire nails into an appropriate work surface only. Do not attempt to fire nails into

goggles during use, maintenance, and reloading.

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

25. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When 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
