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.  
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.  
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.  
b. use personal protective equipment.  
Always wear ANSI-approved eye  
protection during setup and use.  
c. Prevent unintentional starting.  
Ensure the Power Switch (133) is in  
the off-position before connecting  
to power source or moving the  
compressor.  
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.  
4. Compressor use and care  
a. do not use the compressor if the  
Power Switch (133) does not turn  
it on and off. Any compressor that  
cannot be controlled with the Power  
Switch is dangerous and must be  
repaired.  
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.  
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.  
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.  
d. Maintain the compressor. Keep  
the compressor clean for better  
and safer performance. Follow  
4. do not use to supply breathing air.

a. Make sure your extension cord is in  
good condition.  
b. 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.  
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.  
15. Industrial applications must follow OSHA  
guidelines.  
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.  
16. Maintain labels and nameplates on the  
compressor. These carry important  
safety information. If unreadable or  
missing, contact Harbor Freight Tools for  
a replacement.  
14. USE OF AN EXTENSION CORD IS NOT  
RECOMMENDED. If you choose to use  
an extension cord, use the following  
guidelines:  
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.

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. 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.  
SAVE thESE  
INStRuCtIONS.  
2. Do not modify the plug provided – if it will  
not fit the outlet, have the proper outlet  
installed by a qualified electrician.  
GROuNdING  
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.

qualified electrician.  
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

Note: As long as the Power Switch (133) is  
ON, the operation of the Air Compressor  
is automatic, controlled by an internal  
pressure switch. The Compressor will  
turn on automatically when the air  
pressure drops to 120 PSI, and will turn  
off automatically when the air pressure  
reaches 150 PSI. IMPORtANt: The  
internal pressure switch is not user  
adjustable. do not make changes  
to the air pressure settings of the

to the automatic pressure levels may  
cause excess pressure to accumulate,

LIMItEd 1 YEAR / 90 dAY WARRANtY  
Harbor Freight Tools Co. makes every effort to assure that its products meet high quality  
and durability standards, and warrants to the original purchaser that for a period of one year  
from date of purchase that the tank is free of defects in materials and workmanship (90 days  
if used by a professional contractor or if used as rental equipment). Harbor Freight Tools  
also warrants to the original purchaser, for a period of ninety days from date of purchase,  
that all other parts and components of the product are free from defects in materials and  
workmanship. This warranty does not apply to damage due directly or indirectly to misuse,  
abuse, negligence or accidents, repairs or alterations outside our facilities, normal wear and  
tear, or to lack of maintenance. We shall in no event be liable for death, injuries to persons or  
property, or for incidental, contingent, special or consequential damages arising from the use of  
our product. Some states do not allow the exclusion or limitation of incidental or consequential  
damages, so the above limitation of exclusion may not apply to you. THIS WARRANTY IS  
EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING  
THE WARRANTIES OF MERCHANTABILITY AND FITNESS.  
To take advantage of this warranty, the product or part must be returned to us with  
transportation charges prepaid. Proof of purchase date and an explanation of the complaint  
must accompany the merchandise. If our inspection verifies the defect, we will either repair or  
replace the product at our election or we may elect to refund the purchase price if we cannot  
readily and quickly provide you with a replacement. We will return repaired products at our  
expense, but if we determine there is no defect, or that the defect resulted from causes not  
within the scope of our warranty, then you must bear the cost of returning the product.  
This warranty gives you specific legal rights and you may also have other rights which  
vary from state to state.
