7. Drain Tank daily and after use. Internal rust causes
tank failure and explosion.
8. Add correct amount of compressor oil before first
use and every use. Operating with low or no oil
causes permanent damage and voids warranty.
9. Do not remove the valve cover or
adjust internal components.
10. Compressor pump head gets hot during
operation. Do not touch it or allow children nearby
during or immediately following operation.
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. Industrial applications must follow OSHA guidelines.
14. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
15. This product is not a toy.
Keep it out of reach of children.
16. Operate unit on level surface. Check oil level
daily and fill to marked level if needed.
17. 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. A qualified electrician familiar with local electrical
codes in your area must connect the compressor
to a power supply.%See Figure B: Power Supply.
2. WARNING! Electrical connections must be
properly grounded. Ground connections should
be connected at the grounding screw.
3. WARNING! To reduce the risk of electrical hazards,
fire hazards or damage to the compressor,
use proper circuit protection. Your compressor
is wired at the factory for operation using the
voltage shown. Connect the compressor to a
power source with the correct breaker size.
4. WARNING! Do not connect to
prewired posts (i.e., the Motor).
5. CAUTION! Overheating, short circuiting and fire
damage will result from inadequate wiring.

2. The oil level should be at the center of the “FULL”
level on the Oil Sight Glass, as shown in Figure D.
Add oil as needed to maintain this level.
Do not let the oil level go below the center dot
(LOW as shown below) and do not overfill
the oil so that it is above the center dot
(OVERFILL as shown below).

3. To add oil:
a. Remove the Oil Breather Cap.
b. Using a funnel to avoid spills, pour enough
oil into the Pump Crankcase to reach the
“FULL” level in the Oil Sight Glass.
c. Replace the Oil Breather Cap.
E&$*- SAE 30W, non-detergent,
Air Compressor Oil (sold separately) is
recommended for use with this compressor.
4. If uncertain which oil to use for this compressor,

1. Close the Drain Valve f?**%<"3'(*%Vg1
2. Check for oil leaks and check the oil level
(See ″Checking the Oil″ on page Pg1
3. Close the in-line Shutoff Valve between
the Air Compressor and the air hose.
4. Turn the Power Switch ON.
5. Allow the Air Compressor to build
up pressure until it cycles off.
E&$*- At the beginning of the day’s first use
of the Air Compressor, check for air leaks by
applying soapy water to connections while the
Air Compressor is pumping and after pressure
cut-out. Look for air bubbles. If air bubbles are
present at connections, tighten connections.
Do not use the Air Compressor unless all
connections are air tight, the extra air leaking
out will cause the Air Compressor to operate too
often, increasing wear on the Air Compressor.
E&$*- As long as the Power Switch is 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 125 PSI, and will turn off
automatically when the air pressure reaches 150 PSI.

6. Adjust the Regulator Knob so that the air output is
enough to properly power the tool, but the output
will not exceed the tool’s maximum air pressure
at any time. Turn the knob clockwise to increase
the pressure and counter-clockwise to decrease
pressure. Adjust the pressure gradually, while
checking the air output gauge to set the pressure.
7. Make sure the air tool’s throttle or switch is in the
OFF position. Connect the air tool to the air hose.
8. Open the in-line Shutoff Valve.
9. Use the air tool as needed.
10. After the job is complete, turn the Power Switch OFF.
11. Close the in-line Shutoff Valve.
12. Bleed air from the tool then disconnect the tool.
13. Place a collection pan under the Drain Valve.
14. Open the Drain Valve two or three turns ONLY.
When all the pressure and moisture is released,
close the Drain Valve.
Do not remove the Drain Valve.

1. If the Air Compressor automatically shuts off
before reaching its normal cutoff pressure:
a. Shut off all attached tools.
b. Wait until the Air Compressor
cools down (about 10 minutes);
c. If the unit does not start up again
on its own, press the Reset Button
to start the Air Compressor;
d. Resume operation.
2. Possible causes of repeated automatic
shut off of the Air Compressor are:
a. Using a cord that is too long or narrow;
b. An air leak or open hose causing
the Air Compressor to cycle too
often and build up heat.
3. Correct any issues before further use to
avoid damage to the Air Compressor.
