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. Release the pressure in the
storage tank before moving.
12. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
13. 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.
14. 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.
15. Industrial applications must follow OSHA guidelines.
16. Maintain labels and nameplates on the
compressor. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
17. This product is not a toy.
Keep it out of reach of children.
18. 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.

4. Turn Power Switch to AUTO.
5. Allow Air Compressor to build up
pressure until it cycles off.
M&$*- 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.
