GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
serious injury.
SAVE THESE INSTRUCTIONS
Use compressed air only: Clean, dry, regulated compressed air at no more than
90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled
gas as a power source for this tool.
1.

Page 3SKU 95801 For technical questions, please call 1-800-444-3353.
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
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 Hammer.
Do not operate power tools in explosive atmospheres, such as in the pres-
ence of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
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.
Stay alert. Watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power tool while tired or under the influence
of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
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.
Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Carrying power tools with your finger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents.
Be sure all tools and/or attachments used with this Air Hammer are secure
before plugging in or turning on the air supply.
Be careful when connecting/disconnecting air supply. It is recommended to use
quick disconnects (not included) rather than screw-on air connections.
Always disconnect the air supply when this Air Hammer is not being used.
Use ONLY the attachments that come with this Air Hammer. Using or altering
other parts/attachments could damage this tool or cause personal injury.
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.
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.
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.

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.
Do not use the Air Hammer if the Power Switch does not turn it on or off. Any
tool that cannot be controlled with the Power Switch is dangerous and must be
replaced.
Disconnect the air supply before making any adjustments, changing acces-
sories, 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.
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.
Maintain tools with care. Keep cutting tools sharp and clean. Properly main-
tained 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.
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
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the “Inspection, Maintenance, And Cleaning” section of this manual.
Use of unauthorized parts or failure to follow maintenance instructions may create
a risk of injury.
SPECIFIC SAFETY RULES
Maintain labels and nameplates on the Air Hammer. These carry important infor-
mation. If unreadable or missing, contact Harbor Freight Tools for a replacement.
Maintain a safe working environment. Make sure there is adequate surrounding
workspace. Do not use this product in a damp or wet location.
When using this Air Hammer, always maintain a firm grip on the tool with both
hands to resist starting torque.
Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the air supply or the Air Hammer switch.

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.
Never leave this Air Hammer unattended when it is plugged into an air supply.
Turn off the tool, and unplug it from an air supply before leaving.
WARNING: Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities, contains 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
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as those dust masks that are spe-
cially designed to filter out microscopic particles. (California Health & Safety Code
§ 25249.5, et seq.)

OPERATION INSTRUCTIONS
With the proper tool attached to the Air Hammer, attach your air supply to the Air
Inlet (7) at the base on the Housing (1). Turn on the air supply. Carefully place the
tool against the surface of the project you are working with. Make sure the project
is in a vise or attached to something that holds it securely so it cannot be moved
out of position.
Set the Air Regulator (11) located at the base of the Housing (1). Air pressure
should not exceed 90 PSI. Test the action of the Air Hammer and adjust the
Air Regulator (11) as necessary.
Use a light touch on the Trigger (8). Never force the Air Hammer against the surface
you are working with. Easy, light pressure works best.
WARNING: If the Air Hammer is being used as a Scaler, use a ANSI-approved full
face shield and not just safety goggles to protect against Needles that may snap
off and could possibly cause personal injury.
INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure air compressor is unplugged and that the Air Hammer
is disconnected from its Air Supply before performing any inspection, maintenance,
or cleaning procedures.
BEFORE EACH USE, inspect the general condition of this tool. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts, damaged
