Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
Do not operate air compressors in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Air Compressors create sparks
which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating an air tool. Dis-
tractions 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. Children should
not be allowed in the work area.

PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operating
an air tool. Do not use an air tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating air 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 (23) is in its “OFF” posi-
tion, all pressure is safely released, and the unit is unplugged before moving
the Compressor and before performing any service, maintenance, or cleaning
procedures on the unit.
Remove adjusting keys or wrenches before turning the Compressor on. A
wrench or a key that is left attached to a rotating part of the machine 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 air tool in unexpected situations.
Use safety equipment. Always wear eye protection. Always wear ANSI-approved
safety impact glasses and hearing protection under a full face shield during use.
TOOL USE AND CARE
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 use the Compressor if the Compressor’s Power Switch (23) does not
turn it on or off. Any tool that cannot be controlled with its Power Switch is dan-
gerous and must be replaced.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Properly maintained tools 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.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.

SPECIFIC SAFETY RULES AND PRECAUTIONS
CAUTION! Your Warranty is voided if:
You drop the Air Compressor. Always lift the Air Compressor using its
Handle.
DANGER! This Air Compressor is NOT equipped and should not be used
“as-is” to supply breathing air. For any application of air for human consump-
tion, you must fit the Air Compressor with suitable in-line safety and alarm equip-
ment (not included). This additional equipment is necessary to properly filter and
purify the air to meet minimal specifications for Grade D breathing as described
in Compressed Gas Association Commodity Specification G 7.1-1966, OSHA 29
CFR 1910. 134, and/or Canadian Standards Associations (CSA). In the event the
Air Compressor is used for the purpose of breathing air application and proper in-
line safety and alarm equipment is not simultaneously used, existing warranties
are void, and Harbor Freight Tools disclaims any liability whatsoever for any loss,
personal injury, or damage.
DANGER! Never attempt to repair or modify the Air Tank (17). Welding, drilling,
or any other modification will weaken the Tank resulting in damage from rupture or
explosion. Always replace worn, cracked, or damaged Tanks.
Maintain labels and nameplates on the Air Compressor. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replace-
ment.
Make sure all tools and equipment used with the Air Compressor are rated to
the appropriate capacity. Do not use any tool or equipment that does not operate
from 100 PSI to 135 PSI.
Drain the Air Compressor every day. Do not allow excessive moisture to build
up inside the Air Compressor’s Tank. Do not open the Drain Valve (18) with more
than 10 PSI of air pressure in the Tank. Do not unscrew the Drain Valve so that
more than four threads are showing.
Avoid injury. Never direct air hose (not included) at people or animals.
Do not alter, remove, or tamper with the Safety Valve (5).

Make sure the Air Compressor is located on a flat, level, sturdy surface capable
of supporting the weight of the Compressor, operator(s), and any additional
tools and equipment.
Do not move or transport the Compressor if the Air Tank (17) is under pres-
sure.
Industrial applications must follow OSHA guidelines.
Never stand on the Air Compressor. Serious injury could result if the Compres-
sor is tipped.
Never leave the Air Compressor unattended when it is plugged in and running.
Turn off the Compressor, and unplug the unit before leaving.
Do not allow children and other unauthorized people to handle or play with
the Air Compressor.
Do not modify the factory set pressure shutoff or startup switches. This tool will
do the work better and safer at the speed and capacity for which it was designed.
Avoid body contact with oils and lubricants used in the Compressor. If swal-
lowed, seek medical treatment immediately. For skin contact, immediately wash
with soap and water. For eye contact, immediately flush eyes with clean water.
WARNING! Risk of fire or explosion. Do not spray flammable liquid in a confined
area or towards a hot surface. Spray area must be well ventilated. Do not smoke
while spraying or spray where spark or flame is present. Arcing parts: Keep Com-
pressor at least 20 feet away from explosive vapors, such as when spraying with
a spray gun.
Risk of bursting. Do not adjust Regulator to result in output pressure greater than
marked maximum pressure of attachment.
Risk of injury. Do not direct air stream at body. To reduce the risk of electric shock,
do not expose to rain. Store indoors.
WARNING! The brass components of this product contain lead, a chemical known
to the State of California to cause birth defects (or other reproductive harm). (Cali-
fornia Health & Safety code § 25249.5, et seq.)
People with pacemakers should consult their physician(s) before use. Elec-
tromagnetic fields in close proximity to heart pacemaker could cause pacemaker
interference or pacemaker failure.
WARNING! The warnings and precautions discussed in this 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.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool.
Never remove the grounding prong from the plug. Do not use the tool if the
power cord or plug is damaged. If damaged, have it repaired by a service facil-
ity before use. If the plug will not fit the outlet, have a proper outlet installed by
a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a
properly grounded outlet. If the tool should electri-
cally malfunction or break down, grounding pro-
vides a low resistance path to carry electricity away
from the user, reducing the risk of electric shock.
(See 3-Prong Plug and Outlet.)
The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire in the
cord must be the only wire connected to the tool’s
grounding system and must never be attached to an electrically “live” terminal. (See
3-Prong Plug and Outlet.)
Your tool must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like
those in the following illustration. (See 3-Prong Plug and Outlet.)

OPERATING INSTRUCTIONS
Note: Prior to starting the Compressor, read and familiarize yourself with the To
Stop the Compressor procedures listed below.
To Start The Compressor:
Check to make sure the Air Tank’s Drain Valve (18), located at the bottom of the Air
Compressor, is fully closed. Pull on the Safety Valve (5) to verify that it is unstuck.
(See Figure A.)
Connect an air hose (not included) to the air outlet of the Compressor. (See Figure
A.)
Plug the Power Cord (35) into the nearest 120 volt, grounded, electrical outlet.
Turn the Power Switch (23) to its “ON” position to start the Compressor.
(See Figure A.)
Wait until the Tank Pressure Gauge (28) reaches at least 100 PSI before attempting
to operate the Compressor. (See Figure A.)
Once the Tank Pressure Gauge (28) reaches 100 PSI, adjust the Regulator Valve
(30) to feed the desired PSI to the air hose. To do so, turn the Regulator Valve
clockwise to increase, or counterclockwise to decrease the PSI. The Tool Pressure
Gauge (28) will indicate the PSI being delivered to the air hose. (See Figure A.)
NOTE: When the maximum air pressure,135 PSI is reached as indicated by the
Tank Pressure Gauge (28), the motor will stop. The Compressor will automatically
restart when the air pressure drops below 100 PSI. (See Figure A.)
IMPORTANT: The Air Compressor features an Overload Protector (24) button
which, in case of overheating, will automatically shut down the Compressor. Should
the Compressor shut down, turn the Power Switch (23) to its “OFF” position. Wait
several minutes until the Compressor cools down. Press the Overload Protector
button to reset, and turn the Power Switch to its “ON” position to restart the unit.
The Compressor will not restart unless it has cooled down enough, regardless of
pushing the Overload Protector Button. (See Figure A.)
To Stop The Compressor:
Turn the Power Switch (23) to its “OFF” position. (See Figure A.)
WARNING! Unplug the Air Compressor’s Power Cord (35) from the electrical
outlet. (See Figure A.)

INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure the Power Switch (23) of the Air Compressor is in its “OFF”
position, all air pressure has been released from the unit, and the unit is unplugged
from its electrical outlet before performing any inspection, maintenance, cleaning
procedures, or leaving the unit unattended.
Before each use, inspect the general condition of the Air Compressor. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, loose air fittings, and any other condition that may affect
the safe operation of the Compressor. If abnormal noise or vibration occurs, have
the problem corrected before further use. Do not use damaged equipment.
Daily, purge the Air Tank (17) of all air and moisture to prevent corrosion. To do so,
slowly and carefully unscrew (no more than four threads) the Drain Valve (18) until
the compressed air and condensation begins to be released from the Tank. Allow
sufficient time for all of the air and condensation to escape from the Tank. Then,
firmly re-tighten the Drain Valve.
CAUTION! All maintenance, service, or repairs not mentioned in this manual
must only be performed by a qualified service technician.
