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 pur-
pose for which it was not intended.
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.
8.
Do not overreach. Keep proper footing and balance at all times. Do not reach
over or across running machines or air hoses.
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.
11.
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.
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.
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 trig-
ger, 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 dam-
aged 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 re-
placed by a qualified technician. Do not use the tool if the trigger does not oper-
ate properly.
15.
16.
Guard against electric shock. Prevent body contact with grounded surfaces
such as pipes, radiators, ranges, and refrigerator enclosures.
Replacement parts and accessories. This product is to be repaired and ser-
viced 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.
17.
18.
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.
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 compres-
sor 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.
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 qualified technician.
20.
21.
Compressed air only. Never use combustible gas as a power source.
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 the tool contains fasteners.
22.
23.
Disconnect air supply before loading the Nailer. Before reloading (or making
any adjustments to) the Nailer, make sure the compressed air is disconnected.
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 an angle. Fasteners can ricochet causing per-
sonal 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.
24.
25.
Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.
Take caution, as some woods contain preservatives such as copper chro-
mium arsenate (CCA) which can be toxic. When working with these materials
extra care should be taken to avoid inhalation and minimize skin contact.
26.
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 and other masonry products
* Arsenic and chromium from chemically treated lumber.
(California Health & Safety Code § 25249.5, et seq.)
26.
27.
Stay within air pressure capacity. Never operate the Nailer above 125 PSI.
Hold tool away from head and body. During operation the Nailer may kick back
causing injury.
28.
29.
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.
Avoid working alone. If an accident happens, an assistant can bring help.
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.
