IMPORTANT SAFETY INFORMATION
General Safety Warnings
WARNING Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The warnings, precautions, 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.
1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. Do not operate the Compressor in explosive
atmospheres, such as in the presence
of flammable liquids, gases or dust.
Compressor motors produce sparks
which may ignite the dust or fumes.
c. Keep children and bystanders away
from an operating compressor.
2. Electrical safety
a. Compressor plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with grounded
compressors. Standard plugs and matching
outlets will reduce risk of electric shock.
b. Do not expose compressor to rain or wet
conditions. Water entering a compressor
will increase the risk of electric shock.
c. Do not abuse the cord. Never use the
cord for unplugging the compressor.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled
cords increase the risk of electric shock.
3. Personal safety
a. Stay alert, watch what you are doing and
use common sense when operating this
compressor. Do not use this compressor
while you are tired or under the influence
of drugs, alcohol or medication. A moment
of inattention while operating a compressor
may result in serious personal injury.
b. Use personal protective equipment.
Always wear ANSI-approved eye
protection during setup and use.
c. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source or moving the compressor.
4. Compressor use and care
a. Do not use the compressor if the switch
does not turn it on and off. Any compressor
that cannot be controlled with the switch
is dangerous and must be repaired.
b. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the compressor.
Such preventive safety measures reduce the
risk of starting the compressor accidentally.
c. Store an idle compressor out of the reach
of children and do not allow persons
unfamiliar with the compressor or these
instructions to operate it. A compressor is
dangerous in the hands of untrained users.

d. Maintain the compressor. Keep the
compressor clean for better and safer
performance. Follow instructions for
lubricating and changing accessories.
Keep dry, clean and free from oil and grease.
Check for misalignment or binding of moving
parts, breakage of parts and any other
condition that may affect the compressor’s
operation. If damaged, have the compressor
repaired before use. Many accidents are
caused by a poorly maintained compressor.
e. Use the compressor in accordance with
these instructions, taking into account
the working conditions and the work to
be performed. Use of the compressor for
operations different from those intended
could result in a hazardous situation.
5. Service
a. Have your compressor serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the compressor is maintained.
Air Compressor Safety Warnings
1. 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 compressor
at least 20 feet away from explosive vapors,
such as when spraying with a spray gun.
2. Risk of bursting - do not adjust regulator higher
than marked maximum pressure of attachment.
3. Risk of injury - do not direct air
stream at people or animals.
4. Do not use to supply breathing air.
5. Do not leave compressor unattended
for an extended period while plugged in.
Unplug compressor after working.
6. Keep compressor well-ventilated.
Do not cover compressor during use.
7. Start and run the vehicle engine
during inflation period.
8. Do not remove the valve cover or
adjust internal components.
9. Compressor head gets hot during operation.
Do not touch it or allow children nearby during
or immediately following operation.
10. Do not use the air hose to move the compressor.
11. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
12. All air line components, including hoses, pipe,
connectors, filters, etc., must be rated for a minimum
working pressure of 150 PSI, or 150% of the
maximum system pressure, whichever is greater.
13. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
14. This product is not a toy.
Keep it out of reach of children.
15. Operate unit on level surface.
16. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
17. 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).
(California Health & Safety code § 25249.5, et seq.)
18. This Compressor will automatically shut
off on overload or under excessive heat.
Should this occur, turn the Power Switch to
its “OFF” position. Wait until the Compressor
cools. Then, turn the Power Switch to
its “ON” position to resume work.
SAVE THESE INSTRUCTIONS.
