SKU 40115 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 filings or wood chips. Wear a NIOSH-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

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. 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.
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 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

SKU 40115 Page 4For technical questions, please call 1-800-444-3353.
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. Compressed air only. Never use combustible gas as a power source.
21. 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 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 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.
24. Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly 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 100 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.

TestingThe Single Sequential SafetyTrip Mechanism
Warning: Even though the nailer should be empty during this procedure, ALWAYS point
the nailer/Stapler at a piece of scrap wood when testing.
1. The Nailer/Stapler should not fire if the nose is not depressed against the workpiece.
This tool has a contact safety tip mechanism, which is designed to prevent inadvertent
firing. The tool will only fire if the Safety (42) is resting on the workpiece prior to pulling
the Trigger (38).
2. Make sure the tool is disconnected from the air supply.
Operation
For best service you should incorporate an oiler, regulator, and inline filter, as shown in the
diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor
Freight Tools.
1. You will need to prepare a 1/4” air connector (sold separately) to connect to the air inlet
on the Nailer/Stapler First, wrap the 1/4” air connector (not included) with pipe thread
seal tape before connecting to a 3/8” ID Air Source Hose (not included). Connect the Air
Source Hose to the Air Plug (77).
Note: If you are not using an automatic oiler system, before operation, add a few drops of
Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of
continual use.
2. Set the air pressure on your compressor to 60-100 PSI. Do not exceed the maximum air
pressure of 100 PSI.
3. Check the air connection for leaks.
Note: The amount of air pressure effects how deep the nails/staples will be driven. It is
suggested that you experiment on scrap material.
4. Check the air connection for leaks and disconnect the Nailer/Stapler.
