General Compressor 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.
Work area safety 1.
Keep work area clean and well a.
lit. Cluttered or dark areas invite
accidents.
Do not operate the Compressor b.
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.
Keep children and bystanders c.
away from an operating
compressor.
Electrical safety 2.
Compressor plugs must match a.
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.
Do not expose compressor to rain b.
or wet conditions. Water entering
a compressor will increase the risk
of electric shock.
Do not abuse the cord. Never c.
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.
Personal safety 3.
Stay alert, watch what you are a.
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.
Use personal protective b.
equipment. Always wear eye
protection. Safety equipment
such as a dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce personal
injuries.
Prevent unintentional starting. c.
Ensure the switch is in the off-
position before connecting to
power source or moving the
compressor.
Only use safety equipment d.
that has been approved by an
appropriate standards agency.
Unapproved safety equipment may
not provide adequate protection.
Eye protection must be ANSI-
approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.
Compressor use and care 4.
Do not use the compressor if the a.
switch does not turn it on and
off. Any compressor that cannot
be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the b.
power source before making
any adjustments, changing
accessories, or storing the
compressor. Such preventive
safety measures reduce the risk of
starting the compressor accidentally.
Store an idle compressor out of c.
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.
Maintain the compressor. Keep d.
the compressor clean for better
and safer performance. Following
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.
Use the compressor in e.
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.
Service 5.
Have your compressor serviced a.
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
Risk of fire or explosion - do not 1.
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.
Risk of bursting - Do not adjust 2.
regulator higher than marked
maximum pressure of attachment.
Risk of injury - Do not direct air 3.
stream at people or animals.
To reduce the risk of electric shock, 4.
do not expose to rain. Store indoors.
Wear ANSI-approved safety goggles 5.
during use.
Do not use to supply breathing air. 6.
Drain Tank daily and after use. 7.
Internal rust causes tank failure and
explosion.
Add correct amount of compressor 8.
oil before first use and every use.
Operating with low or no oil causes
permanent damage and voids
warranty.
Do not remove the valve cover or 9.
adjust internal components.
Compressor head gets hot during 10.
operation. Do not touch it or allow
children nearby during or immediately
following operation.
Do not use the air hose to move the 11.
compressor.
Release the pressure in the storage 12.
tank before moving.
The use of accessories or 13.
attachments not recommended by
the manufacturer may result in a risk
of injury to persons.
All air line components, including 14.
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.
USE OF AN EXTENSION CORD 15.
IS NOT RECOMMENDED. If you
choose to use an extension cord, use
the following guidelines:

current your product will draw. An
undersized cord will cause a drop in
line voltage resulting in loss of power
and overheating. Table A shows
the correct size to use depending
on cord length and nameplate
ampere rating. If in doubt, use the
next heavier gauge. The smaller the
gauge number, the heavier the cord.
Industrial applications must follow 16.
OSHA guidelines.
Maintain labels and nameplates 17.
on the compressor. These carry
important safety information. If
unreadable or missing, contact
Harbor Freight Tools for a
replacement.
This product is not a toy. Keep it out 18.
of reach of children.
Operate unit on level surface. Check 19.
oil level daily and fill to marked level if
needed.
People with pacemakers should 20.
consult their physician(s) before
use. Electromagnetic fields in close
proximity to heart pacemaker could
cause pacemaker interference or
pacemaker failure.
WARNING: The brass components 21.
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.)
The warnings, precautions, 22.
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.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
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 compressor.
Never remove the grounding
prong from the plug. Do not
use the compressor if the
power cord or plug is
damaged. If damaged, have it
repaired by a service facility
before use. If the plug will not
fit the outlet, have a proper
outlet installed by a qualified
electrician.
110-120 V~ Grounded
Compressors: Compressors with
Three Prong Plugs
In the event of a malfunction or 1.
breakdown, grounding provides a
path of least resistance for electric
current to reduce the risk of electric
shock. This compressor is equipped
with an electric cord having an
equipment-grounding conductor and
a grounding plug. The plug must be

plugged into a matching outlet that
is properly installed and grounded in
accordance with all local codes and
ordinances.
Do not modify the plug provided – 2.
if it will not fit the outlet, have the
proper outlet installed by a qualified
electrician.
Improper connection of the 3.
equipment-grounding conductor can
result in a risk of electric shock. The
conductor with insulation having
an outer surface that is green with
or without yellow stripes is the
equipment-grounding conductor. If
repair or replacement of the electric
cord or plug is necessary, do not
connect the equipment-grounding
conductor to a live terminal.
Check with a qualified electrician or 4.
service personnel if the grounding
instructions are not completely
understood, or if in doubt as to
whether the compressor is properly
grounded.
Use only 3-wire extension cords that 5.
have 3-prong grounding plugs and
3-pole receptacles that accept the
compressor’s plug.
Repair or replace damaged or worn 6.
cord immediately.
