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. 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 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 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. 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 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. 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.

Page 4SKU 92918 For technical questions, please call 1-800-444-3353.
16. 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.
17. Use proper size and type extension cord. If an extension cord is required for the
air compressor, 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.
18. 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.
19. Compressed air only. Never use combustible gas as a power source.
20. 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.
21. Disconnect air supply before loading the Nailer. Before reloading (or making
any adjustments to) the Nailer, make sure the compressed air is disconnected.
22. 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 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.
23. Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.
24. 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 and other masonry products
* Arsenic and chromium from chemically treated lumber.
(California Health & Safety Code § 25249.5, et seq. )

Page 5SKU 92918 For technical questions, please call 1-800-444-3353.
25. Stay within air pressure capacity. Never operate the Nailer above 125 PSI.
26. Hold tool away from head and body. During operation the Nailer may kick back
causing injury.
27. 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.
28. 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.

Operating the Nailer
1. Attach the Nailer to the air supply at the Air Inlet (61). Start your compressor and
check the pressure making sure it is set at the recommended 70-125 PSI and not to
go over the maximum 125 PSI.
2. To fire, first rotate the Trigger Lock (28) to the unlocked position, as shown on page
6. Then, place the Safety (59) of the Nailer on the workpiece. The Nailer should not
fire if the Safety (59) is not depressed. Once depressed, gently and briefly squeeze
the Trigger (51) once. Do not fire repeatedly. Nails could bounce off one another,
damaging the workpiece or causing PERSONAL INJURY.
3. If the nails are not being driven deeply enough or are being driven too deeply, then
adjust the Depth Adjuster (56). It make take some practice and experience to get
the desired results. If more depth adjustment is needed, the air supply pressure can
be adjusted, but ONLY within the recommended 70-125 PSI.
4. The direction of the air exhaust can be changed by loosening the Exhaust Screw
(1) in the center of the Exhaust Cover (2), rotating the Exhaust Cover to the desired
direction and retightening the Exhaust Screw (1)
5. Do not press the Safety (59) of the Nailer against the work surface with extra force.
Allow the tool to do the work. Always allow the tool to recoil off the workpiece.
6. When finished using the Nailer, always rotate the Trigger Lock (28) to the locked
position and disconnect the tool from its compressed air supply. Empty the Nail
Canister (100) completely of nails. Attempt to fire the Nailer into a piece of scrap
wood to ensure it is disconnected and is incapable of firing any nails.
7. Make sure to store the Nailer in its Carrying Case and in a clean, dry, safe location
out of reach of children.
