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 pur-  
pose 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. 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 inop-  
erable, 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 wrench-  
es 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 towards your-  
self 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 opera-

tion. Any part that is damaged should be properly repaired or replaced by a quali-  
fied 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 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. 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 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 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 the tool contains fasteners.  
22. disconnect air supply before loading the Nailer. Before reloading (or making  
any adjustments to) the Nailer, make sure 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 an angle. Fasteners can ricochet causing personal  
injury. Never fire the Nailer into the air, or point it toward yourself or another per-  
son. 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 chromi-  
um arsenate (ccA) which can be toxic. When stapling or nailing these materials  
extra care should be taken to avoid inhalation and minimize skin contact.  
26. 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.)  
27. Stay within air pressure capacity. Never operate the Nailer above 120 PSI.  
28. Hold tool away from head and body. During operation the Nailer may kick back  
causing injury.  
29. 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.  
30. Avoid working alone. If an accident happens, an assistant can bring help.  
31. Warning: the warnings, cautions, and instructions discussed in this instruc-  
tion manual cannot cover all possible conditions and situations that may oc-  
cur. 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

Other people in the work area must also wear ANSI approved impact safety  
goggles.  
1. Attach the Nailer to the air supply at the Air Inlet (57). Start your compressor and  
check the pressure making sure it is set at the recommended 70-120 PSI.  
2. Rotate the Deflector (6) so that the exhaust air blast will be directed away from the  
operator.  
3. To re, place the Nose Cushion (89) of the Nailer on the workpiece. With the  
Trigger (47), Nails can only be driven one way. First, depress the Nose Cushion  
against the workpiece. Then, pull the Trigger. The Nailer should not fire if the  
Nose Cushion is not depressed. This feature is helpful when precise fastener  
placement is required. Also, it may reduce the possibility of injury to you or to oth-  
ers working with you.  
4. Do not press the Nose Cushion (89) against the work surface with extra force. Al-  
low the tool to do the work. Always allow the tool to recoil off the work surface.  
5. When finished using the Nailer, always disconnect the tool from its compressed  
air supply. Empty the Magazine (69) 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.  
6. Make sure to store the Nailer in its accessory Carrying Case and in a clean, dry,  
safe location out of reach of children.

Inspection, maintenance, and cleaning  
1.  
Inspect the Nailer frequently and lubricate periodically with Pneumatic tool oil,  
then wipe dry. Do not use detergent oil or additives as these lubricants will cause  
accelerated wear to the internal seals.  
2.  
Inspect the air supply filter, if present, before each use and clean or replace as  
necessary. Dirt and water in the air supply filter are major causes of pneumatic  
tool wear. Use a filter/oiler for better performance and longer tool life. The filter  
must have adequate flow capacity for the specific application.  
3.  
4.  
5.  
Clean the external parts of the Nailer with a clean cloth and mild detergent or  
nonflammable solvent. Then, dry.
