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 foot-

wear 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 a qualied

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 brads 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 for an air compressor. 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 compressor.

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, either 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. Use clean, dry, regulated, compressed air at between 70

and 120 PSI. Never use oxygen, carbon dioxide, combustible gases, or any

other bottled gases a power source for this tool.

21. Do not load brads with the trigger or safety depressed. Unintentional

ring may occur. Do not load brads when the air hose is connected to the

tool. Always assume the tool contains brads.

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 brads into an appropriate work surface only. Do not attempt to re

brads into surfaces too hard to penetrate. Do not drive brads on top of other

brads, or at too steep an angle. Brads 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 brads too close to the edge of a workpiece. They may split the

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 120 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.
