10.
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.
11. 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.
12. 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.
13. 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.
14. 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.
15. Stay alert. Watch what you are doing, use common sense.Do not operate any tool when
you are tired.
16. 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.
17. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
18. 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 from Harbor Freight
Tools.
19. 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.
20. 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 breaker to trip or your

panel fuse to break. If this happens, either use the compressor without an extension
cord or find a larger amperage circuit to use.
21. 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
qualified technician.
22. Compressed air only. Use clean, dry regulated, compressed air at 90 PSI. Never use
oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source
for this tool.
23.
Do not load pins 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.
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. 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. Never fire the
Nailer into the air, or point it toward yourself or another person. Always wear ANSI
approved safety goggles during use, maintenance, and reloading.
26. Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.
27. 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. )
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.
