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. 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.

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. 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 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

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 125 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.

Set Up

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 Plug

(41) on the Nailer. First, wrap the 1/4” air connector (not included) with pipe thread seal

tape before connecting to the Air Source Hose (not included). Connect the Air Source

Hose to the Air Plug (41).

Note: If you are not using an automatic oiler system on your air compressor, before operation,

add a few drops of Pneumatic Tool Oil to the airline connection. Remove the air line at the

inlet and put 2 or 3 drops of good quality air tool oil into the air fitting each day of use. With

heavy, prolonged use, do this at least twice a day.

2. Set the air pressure on your compressor to 60-125 PSI. Do not exceed the maximum air

pressure of 125 PSI.

Note: About Air Consumption -CFM Air fastening tools are classified as “intermittent use”,

and, as such, may be operated by compressors of almost any size. Small, portable units

may not be suitable for high volume work, but will satisfactorily power the nailer for work at

a slower rate. The air demand of any fastening tool depends largely upon how quickly the

tool is to be used. PRESSURE - Use the lowest air pressure that will sufficiently drive the

fastener into the wood. This will depend on the density of the wood, and upon the size and

length of the nails being used. Vary the air pressure to adjust the driven depth, without

exceeding hte maximum air pressure of 125 PSI.

3. Check the air connection for leaks.

Unpacking

When unpacking, check to make sure the parts listed on page 10 are included.

If any parts are missing or broken, please call Harbor Freight Tools at the number

on the cover of this manual as soon as possible.

Warning! Disconnect the Nailer from the air compressor whenever loading or servicing.

After disconnecting the Nailer from the air compressor, there could still be enough

air pressure to fire the Nailer. Always fire the trigger repeatedly to make sure all of

the air is expended.

Use the Correct Type of Nails

This nailer uses only “clipped-head” nails, which are collated at an angle of 28°. “Round

Head” nails, collated at 22°, are not to be used in this tool, as they will not feed reliably, and

may cause premature wear of the driver assembly.

Harbor Freight tools offers a variety of compatible fasteners, which are usually collated in

strips of 25. Nails from other manufacturers are also widely available from home centers and

building supply stores. Please note that some manufacturers offer fasteners packaged for

their brand of air nailers, and their nail strips may be longer than the loading slot in this tool.

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 (56) of nails.

3. The Nailer should not fire if the Safety (28) is not depressed against the workpiece.

4. Make sure the Trigger (31) and Safety (28) move freely, without sticking.

5. Connect the air supply to the tool at the Air Plug (41). Set the regulator at the recom-

mended 60 to 125 PSI.

6. Test the tool by depressing the Safety (28) against the workpiece without pulling the

Trigger (31). TheTool must not cycle (fire). If it cycles (fires), stop immediately and

have it repaired by a qualified service technician.

7. Hold the tool away or off of the workpiece. The Safety (28) of the tool should return to

its original position. Point the nailer in a safe direction, towards the scrap wood and

squeeze the Trigger (31). The tool should not cycle (fire). If the tool fires, stop imme-

diately and have it repaired by a qualified service technician.

8. Depress the Safety (28) against the workpiece and squeeze the Trigger (31). The tool

must cycle (fire) only once. Release the Trigger and squeeze it again. The tool must

not cycle (fire). With the Trigger held, carefully lift the nailer and press it against the

workpiece again. The tool must not cycle (fire). If it fails to perform in the manner

explained in bold, have it repaired by a qualified service technician.

Operating the Nailer

1. Attach the Nailer to the air supply at the Air Plug (41). Start your compressor and

check the pressure making sure it is set at the recommended 60-125 PSI and not over

the maximum 125 PSI.

2. After reading the following, it is recommended that you get acquainted with this tool by

practicing on scrap wood until you are familiar with its characteristics.

Always Wear Eye Protection When Using the Air Nailer

3. Turn the Exhaust Cover (4) to direct the air away from the operator.

4. The full sequential trip trigger has a safety device assembled to the nosepiece. The

nailer will not fire unless the serrated collar is depressed. Never attempt to defeat

this mechanism, and never manually hold it back to shoot nails.

5. To place and shoot a single nail, grip the nailer without touching the trigger, and

position the nosepiece on the wood. With your free hand, press down on the top of the

nailer. Give the trigger a quick pull and release.

Clearing Jams

1. Disconnect tool from air hose. Always fire the trigger repeatedly to make sure all of the

air is expended from the Nailer.

2. If a nail is jammed in the discharge area, simply remove it with pliers.

3. If a nail is jammed in the magazine, pull the Magazine Slide (47) all the way back to the

engaged position. Using a screwdriver, attempt to release the jammed nail by probing

either or both of the two openings in the magazine

(see photo below) to release the nail. Pull out the

jammed nail and the remainder of the nail strip that

is still in the magazine. Dispose of the remaining

nail strip; it may be bent or damaged in some other

way.

4. Reload the magazine with a new nail strip. Pull back

on the Magazine Slide (47) and with your other

hand pull the tab down on the Slide Release (58),

and guide the Magazine Slide (47) back into posi-

tion.

If you are unable to clear the nail jam using the method prescribed above, the tool should

be taken to a qualified service technician for proper servicing.

Anytime

any

maintenance or repairs are done (including clearing jams), FIRST:

1. Disconnect the Nailer from the air hose.

2. Empty the Magazine (56) completely.

3. Attempt to fire the Nailer into a piece of scrap wood to ensure that it is disconnected and

is incapable of firing any brads.

4. Always leave the Magazine (56) open during maintenance. The Magazine is spring-

loaded and may cause parts or a nail to fly out of the Nailer.

Probe in these areas with a

screwdriver to release jammed nails.
