Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be
followed to reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1.
Keep work area clean. Cluttered areas invite injuries.
2.
Observe work area conditions. Do not use machines or power tools in damp or
wet locations. Do not expose to rain. Keep work area well lit. Do not use electrically powered tools in the presence of flammable gases or liquids.
3.
Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, extension cords, or air hoses.
4.
Store idle equipment. When not in use, tools must be stored in a dry location to
inhibit rust. Always lock up tools and keep out of reach of children.
5.
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 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 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.
Stay within air pressure capacity. Never operate the Nailer above 90 PSI.

9.
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.
10.
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.
11.
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.
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.
13.
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.
14.
Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15.
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.
16.
Guard against electric shock. Prevent body contact with grounded surfaces such
as pipes, radiators, ranges, and refrigerator enclosures.
17.
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.
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.
19.
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
SKU 93656
For technical questions, please call 1-800-444-3353.
Page 3
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.
20.
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.
21.
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.
22.
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.
23.
Disconnect air supply before loading Nailer. Before reloading (or making any
adjustments to) the Nailer make sure that the compressed air is disconnected.
24.
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.
25.
Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.
26.
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.)
27.
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.

Operating the Nailer
1.
Attach the Nailer to the air supply at the Air Inlet (22). Start your compressor and check
the pressure making sure it is set at the recommended 90 PSI and not to go over the
maximum 90 PSI.
2.
To fire, place the nose of the Nailer on the workpiece. The Nailer should not fire if the
nose is not depressed. Once depressed, gently and briefly squeeze the Trigger (42)
once. Do not fire repeatedly. Pins could bounce off of one another, damaging the work
piece or causing PERSONAL INJURY.
