* The air pressure setting must not exceed job site regulations/restrictions. The air pressure set-

ting must not exceed 90 PSI when being used with work pieces that have a thickness of less than

1-3/4”.

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. 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 lings or wood chips. Wear a NIOSH-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 wrenches. Check that 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 nger 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 nails 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 xtures, 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.

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 qualied 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 from Harbor Freight Tools.

17. Do not operate tool if under the inuence of alcohol or drugs. Read warning

labels if taking prescription medicine to determine if your judgement or reexes

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 re, 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 breaker to trip or your panel fuse to break. If this happens, ei-

ther use a longer air hose, use the compressor without an extension cord, or nd

a larger amperage circuit to use.

19. Maintenance. The maintenance outlined in the “Maintenance” section should be

performed regularly. For your safety, this product should be serviced or repaired

regularly only by a qualied 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 ring

may occur. Do not load nails when the air hose is connected to the tool.

Always assume the tool contains nails.

22. Disconnect air supply before loading the Nailer. Before reloading (or making

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

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

into surfaces too hard to penetrate. Do not drive nails on top of other nails, or at

too steep an angle. Nails can ricochet, causing personal injury. Never re the

Nailer into the air, or point it toward yourself or another person. Always wear

ANSI-approved impact safety goggles during use, maintenance, and reloading.

24. Do not re nails too close to the edge of a workpiece. They may split the

workpiece and y free, causing personal injury.

25. Take caution, as some woods contain preservatives such as copper

chromium arsenate (CCA) which can be toxic. When 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, cement, and 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 to avoid contact with the trigger.

29. Avoid working alone. If an accident happens, an assistant can bring help.

30. 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 the tool performance.

31. 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.
