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 ammable 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. REV 08a

SKU 46309 Page 3For technical questions, please call 1-800-444-3353.
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 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 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 keys and wrenches. Check that keys and 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 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 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. 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 tool. Check your air compressor’s manual for the appropriate size cord.

SKU 46309 Page 4For technical questions, please call 1-800-444-3353.
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. Never use combustible gas as a power source.
21. Do not load nails with the trigger or safety depressed. Unintentional ring
may occur. Do not load nails when the air hose is connected to the tool.
Always assume that the tool contains fasteners.
22. Disconnect air supply before loading Nailer. Before reloading (or making any
adjustments to) the Nailer make sure that the compressed air is disconnected.
23. Fire fasteners into an appropriate work surface only. Do not attempt to re 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 re
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. Do not re fasteners too close to the edge of a workpiece. They may split the
workpiece and y free, causing personal injury.
25. 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. )
26. Stay within air pressure capacity.Never operate the Nailer above 95 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 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.

Testing the Full Sequential Safety Trip Mechanism
Warning: Even though the nailer should be empty during this procedure, ALWAYS point
the nailer at a piece of scrap wood when testing.
1. Make sure the tool is disconnected from the power supply.
2. Completely empty the magazine of nails.
3. The Nailer should not re if the nose is not depressed against the workpiece.
4. Check that the Trigger (29) and the Safety (56) move freely, without sticking - see Figure
1, next page.
5. Connect the air supply to the tool at the Air Inlet (38) set at the recommended 55-95
PSI, and not to go over the maximum 95 PSI.
6. Test the tool by depressing the Safety (56) against the workpiece without pulling the
Trigger (29). The tool must not cycle (re). If it cycles (res), stop immediately and
take the tool to an authorized service technician.
7. Hold the tool away or off of the workpiece. The Safety (56) of the tool should return to
its original position. Squeeze the Trigger (29). The tool should not cycle (re). If it
cycles (res), stop immediately and take the tool to an authorized service technician.
8. Depress the Safety (56) against the workpiece and squeeze the Trigger (29). The
tool must cycle (re) once only. Release the trigger and squeeze it again. The tool
must not cycle (re). With the Trigger held, carefully lift the nailer and press it against
the workpiece again. The tool must not cycle (re). If it fails to act in the manner
described in bold, have it repaired by a qualied service technician.
