5. Do not spray near open flames, pilot lights,
stoves, heaters, the air compressor, or any
other heat source. Most solvents and coatings
are highly flammable, particularly when
sprayed. Maintain a distance of at least 25 feet
from the air compressor. If possible, locate
the air compressor in a separate room.
6. Read all of the information concerning
coating products and cleaning solvents.

Contact the solvent or coating manufacturer as
needed regarding potential chemical reactions.
7. Spraying hazardous materials may result in serious
injury or death. Do not spray pesticide, acid,
corrosive material, fertilizer, or toxic chemicals.
8. Paints and solvents may be harmful or fatal if
swallowed or inhaled. Avoid prolonged skin
contact with solvents or paints as they will
irritate skin. After any contact, immediately
wash off exposed area with hot, soapy water.
9. Air hose fittings may get hot during use.
Allow fittings to cool before disconnecting.

12. Drain Tank daily and after use. Internal rust causes
tank failure and explosion.
13. Do not remove the valve cover or
adjust internal components.
14. Compressor head gets hot during operation.
Do not touch it or allow children nearby
during or immediately following operation.
15. Do not use the air hose to move the compressor.
16. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
17. 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.
18. USE OF AN EXTENSION CORD IS NOT
RECOMMENDED. If you choose to use an
extension cord, use the following guidelines:

a. Make sure your extension cord
is in good condition.
b. Be sure to use an extension cord which
is heavy enough to carry the 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.
19. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
20. This product is not a toy.
Keep it out of reach of children.
21. 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.

1. In the event of a malfunction or 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.
2. Do not modify the plug provided –
if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.
3. Improper connection of the 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.
4. Check with a qualified electrician or service
personnel if the grounding instructions are
not completely understood, or if in doubt as to
whether the compressor is properly grounded.
5. Use only 3-wire extension cords that have
3-prong grounding plugs and 3-pole receptacles
that accept the compressor’s plug.
6. Repair or replace damaged or
worn cord immediately.

3. Route the power cord from the Air Compressor
to the grounded wall outlet, along a safe path
without creating a tripping hazard or exposing
the power cord to possible damage.

1. Pull up on Regulator, then turn Regulator
counterclockwise completely to close.
Push down on Regulator.
2. Plug Power Cord into grounded 120VAC outlet.
3. Turn Power Switch ON.
4. Allow Air Compressor to build up
pressure until it cycles off.
5. Check for air leaks by applying soapy water to
connections while the Air Compressor is pumping
and after pressure cut-out. Look for air bubbles.
If air bubbles are present at connections, tighten
connections. Do not use the Air Compressor unless
all connections are air tight, the extra air leaking
out will cause the Air Compressor to operate too
often, increasing wear on the Air Compressor.
M&$*- As long as the Power Switch is set to ON, the
operation of the Air Compressor is automatic, controlled
by an internal pressure switch. The Air Compressor will
turn on automatically when the air pressure drops to
43.5 PSI, and will turn off automatically
when the air pressure reaches 58 PSI.

1. If the Air Compressor automatically shuts off
before reaching its normal cutoff pressure:
a. Turn Power Switch to OFF position.
b. Unplug Air Compressor.
c. Wait until the Air Compressor
cools down (about 30 minutes).
d. Resume operation.
2. Possible causes of repeated automatic
shut off of the compressor are:
a. Using an extension cord that
is too long or narrow;
b. An air leak or open hose causing the compressor
to cycle too often and build up heat.
c. Turning Air Compressor off and
on again too quickly.
3. Correct any issues before further use to
avoid damage to the compressor.

Following are general guidelines for maintenance checks of the Air Compressor.
M&$*- The environment in which the Air Compressor is used, and the frequency of use will affect how
often you will need to check the Air Compressor components and perform maintenance procedures.
T,"7U-
a. Make sure all nuts and bolts are tight.
b. Drain moisture from filter.
c. Check for abnormal noise or vibration.
d. Check for air leaks.*
e. Wipe off any oil or dirt from the Air Compressor.
* To check for air leaks, apply soapy water to joints while
the Air Compressor is pressurized. Look for air bubbles.

Compressor does
not start or restart
1. Tank(s) already pressurized.
2. Power cord not plugged
in properly.
3. Incorrect power supply.
4. No power at outlet.
5. Thermal overload switch tripped.
6. Building power supply circuit
tripped or blown fuse.
7. Cord wire size is too small or
cord is too long to properly
power compressor.
8. Compressor needs service.
1. No problem. Compressor will start when needed.
2. Check that cord is plugged in securely.
3. Check that circuit matches compressor requirements.
4. Reset circuit breaker, or have outlet
serviced by a qualified technician.
5. See Automatic Shut Off System on page 7.
6. Reset circuit or replace fuse. Check for low voltage
conditions. It may be necessary to disconnect
other electrical appliances from the circuit or
move the compressor to its own circuit.
7. Use larger diameter or shorter extension cord or
eliminate extension cord. See Recommended Wire
Gauge for Extension Cords in Safety section.
8. Have unit inspected by a qualified technician.
Compressor builds
pressure too slowly
1. Incorrect power supply.
2. Working environment too cold.
3. Loose fittings.
1. Check that circuit matches compressor requirements.
2. Move compressor to a warmer location.
3. Reduce air pressure, then check all fittings
with a soap solution for air leaks and tighten
as needed. Do not overtighten.
Compressor not
building enough
air pressure
1. Air filter needs cleaning/replacing.
2. Check Valve needs service.
3. Compressor not large enough for
job.
4. Loose fittings.
5. High altitude reducing air output.
1. Check inlet filter.
Clean and/or replace as needed.
2. Have technician clean or replace, as needed.
3. Check if accessory CFM is met by Compressor.
If Compressor cannot supply enough
air flow (CFM), use a larger Compressor.
4. Reduce air pressure, then check all fittings
with a soap solution for air leaks and tighten
as needed. Do not overtighten.
5. Higher altitudes require compressors with greater output.
Overheating 1. Unusually dusty environment.
2. Extension cord used.
1. Move unit to cleaner environment.
2. Eliminate extension cord.
Compressor
starts and stops
excessively
Loose fittings. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
Excessive noise Loose fittings. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
Air leaks from
pump or fittings
Loose fittings. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
Air leaks from tank Defective or rusted tank. Have tank replaced by a qualified technician.
Drain moisture from tank daily to prevent future corrosion.
