ment 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 foot
wear 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.
Disconnect Air Hose and release any built-up air pressure. Never perform
service on 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.
12.
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
trigger, whether it is attached to an air source or not. Do not point the tool to-
wards yourself or anyone whether it contains fasteners or not.
13.
14.
Stay alert. Watch what you are doing, use common sense. Do not operate any
tool when you are tired.
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.
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 hap-
pens, either use the compressor without an extension cord or find a larger am-
perage 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. Uninten-
tional 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 an-
other person. Always wear ANSI approved safety goggles during use, mainte-
nance, 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 stapling or nailing these
materials extra care should be taken to avoid inhalation and minimize skin con-
tact.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contain chemicals known (to the State of Cali-
fornia) 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 100 PSI.
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.
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.
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.

WARNING: When the Trigger (42) is depressed, the Roofing Nailer will fire if the
Nose of the tool comes in contact with anything.
Do not press the Nose (72) of the Roofing Nailer against the work surface with
extra force. Allow the tool to do the work. Always allow the tool to recoil off the
workpiece.
5.
Caution: While working on roofs, tar and dirt may build up on the Nose of
the Roofing Nailer. This can prevent normal operation. Remove buildup with a
non-flammable solvent. NEVER use gasoline or other flammable solvents. Do
not immerse the Roofing Nailer in an approved solvent beyond the height of the
nail heads, to avoid getting the solvent into the drive cylinder of the tool. Make
sure to dry off the Roofing Nailer before use. Any oil film left after cleanup will
accelerate tar buildup.
