GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
serious injury.
SAVE THESE INSTRUCTIONS
1. Use compressed air only: Clean, dry, regulated compressed air at no more than
100 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled
gas as a power source for this tool.
2. Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
3. Use protection: Always wear ANSI-approved safety eye goggles, dust mask/
respirator, work gloves, hard toed shoes, long sleeve shirt and long pants
when using or servicing this Air Nailer.

For technical questions, please call 1-800-444-3353.
4. Do not operate power tools in explosive atmospheres, such as in the presence
of ammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
5. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
6. Stay alert. Watch what you are doing, and use common sense when operating
a power tool. Do not use a power tool while tired or under the inuence of
drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
7. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
8. Avoid accidental starting. Carrying power tools with your nger on the Trigger
(27) invites accidents.
9. Be sure all tools and/or attachments used with this Air Nailer are secure before
plugging in or turning on the air supply.
10. Be careful when connecting/disconnecting air supply. It is recommended to use
quick disconnects (not included) rather than screw-on air connections.
11. Always disconnect the air supply when this Air Nailer is not being used.
12. Use ONLY the attachments that come with this Air Nailer. Using or altering other
parts/attachments could damage this tool or cause personal injury.
13. Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a moving part of the power tool may result
in personal injury.
14. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
15. Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body
is unstable and may lead to loss of control.
16. Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed. Do not force
the tool and do not use the tool for a purpose for which it is not intended.
17. Do not use the Air Nailer if the Trigger (27) does not turn it on or off. Any tool that
cannot be controlled with the Power Switch is dangerous and must be replaced.

For technical questions, please call 1-800-444-3353.
18. Disconnect the air supply before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the
risk of starting the tool accidentally. Always unplug the tool from its air supply
before performing any inspection, maintenance, or cleaning procedures.
19. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users. Never allow children to come in
contact with this product.
20. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools with a sharp cutting edge are less likely to bind and are easier to control. Do
not use a damaged tool. Tag damaged tools “Do not use” until repaired.
21. Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
SERVICE
1. Tool service must be performed only by qualied repair personnel. Service or
maintenance performed by unqualied personnel could result in a risk of injury.
2. When servicing, use only identical replacement parts. Follow instructions
in the “Inspection, Maintenance, And Cleaning” section of manual. Use of
unauthorized parts or failure to follow instructions may create a risk of injury.
SPECIFIC SAFETY RULES
1. Maintain labels and nameplates on the Air Nailer. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a
replacement.
2. Maintain a safe working environment. Make sure there is adequate surrounding
workspace. Do not use this product in a damp or wet location.
3. When using this Air Nailer, always maintain a rm grip on the tool with both
hands to resist starting torque.
4. Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the air supply or pressing the Trigger (27).
5. Never lay the tool down until it has come to a complete stop. Moving parts can
grab the surface and pull the tool out of your control.
6. Never leave this Air Nailer unattended when it is plugged into an air supply.
Turn off the tool, and unplug it from an air supply before leaving.
7. WARNING: This product contains or, when used, produces a chemical
known to the State of California to cause cancer and birth defects or other
reproductive harm. (California Health & Safety Code § 25249.5, et seq.)

OPERATION INSTRUCTIONS
1. Before use, add a few drops of pneumatic tool oil (not included) into the Inlet.
2. Attach the Air Coupler (61) to Air Inlet using pipe thread seal tape (not included).
Then connect the 3/8” Air Source Hose to the Nailer.
3. Set the working air pressure on the regulator to between 60 and 100 PSI. Do not
exceed 100 Max. PSI.
4. Set the Adjusting Dial (46) to match the corresponding size (1/2”, 5/8”, 3/4”, 7/8”
or 1”) of the fasteners loaded in the Nailer.
Note: When changing pin size, turn the Adjusting Dial to the new depth size BE-
FORE inserting the new pins.
5. Slide the Safety (60) to the side so that the Trigger (27) will function. When ready,
press down on the Trigger (27) to operate.
6. Test before rst use by driving nails into a sample piece of wood. If the fasteners
do not achieve the desired penetration, adjust the air pressure to a higher setting
until desired penetration is achieved.
7. Always make sure the Bracket (40) is ush against the workpiece during use. Always
release the Trigger (27) once the fastener is driven into the workpiece.
8. When ready to operate the Nailer, press down on the Trigger (27). Make sure the
Nailer does not cycle during use. Never use the Nailer if a cycle occurs.
9. In case of a fastener jam, take your nger off the Trigger (27). Rotate the
Trigger Lock/Safety (60) clockwise or counter-clockwise. For instance, a “6
o-clock” position will lock the Trigger (27) and the tool will not re. However, “3
o-clock” and “9 o-clock” positions unlock the Trigger (27), allowing the tool to re.
Note: There is no contact safety for the Trigger (27). When the Trigger Lock/Safety
(60) is disengaged, the Nailer will re.
10. Turn off the air supply and disconnect the Nailer from the regulator. Open the Nozzle
(40) and clear the jammed fasteners with a pair of pliers (not included).
If a jam occurs inside the magazine, depress the upper tip of the Click Lever (59).
The Side Cover (34) will pop open. If needed, open the Nozzle (40) to help clear
the jam. Once the jam is cleared, push the Side Cover (34) back into place and
latch tight using the Click Lever (59).
