Introduction
Air compressor units are intended to provide compressed air to power pneumatic tools, operate spray guns and
supply air for pneumatic valves and actuators. The pumps supplied with these units have oil lubricated bearings.
A small amount of oil carryover is present in the compressed air stream. Applications requiring air free of oil vapor
should have the appropriate filters installed. The air compressor units are to be mounted per the instructions
provided on a solid floor. Any other use of these units will void the warranty and the manufacturer will not be
responsible for problems or damages resulting from such misuse.

Important Safety Information (Continued)
BREATHABLE AIR WARNING
This compressor/pump is not equipped and should not be used “as is” to supply breathing quality
air. For any application of air for human consumption, the air compressor/pump will need to be
fitted with suitable in-line safety and alarm equipment. This additional equipment is necessary to
properly filter and purify the air to meet minimal specifications for Grade D breathing as described
in Compressed Gas Association Commodity Specification G 7.1, OSHA 29 CFR 1910. 134, and/or
Canadian Standards Associations (CSA).
DISCLAIMER OF WARRANTIES
In the event the compressor is used for the purpose of breathing air application and proper in-line
safety and alarm equipment is not simultaneously used, existing warranties shall be voided, and the
manufacturer disclaims any liability whatsoever for any loss, personal injury or damage.

INSTALLATION INSTRUCTIONS
Disconnect, tag and lock out power source then release all pressure
from the system before attempting to install, service, relocate or perform any
maintenance.
GETTING STARTED
Do not lift or move unit without appropriately rated equipment. Be sure the unit is
securely attached to lifting device used. Do not lift unit by holding onto tubes or
coolers. Do not use unit to lift other attached equipment.
Never use the wood shipping skids for mounting the
compressor.
GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding
wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not use grounding adapter.
This product is for use on a nominal 120 volt circuit and has a grounding plug similar to the plug illustrated in
Figure 2. If the listed conditions cannot be met or if nuisance tripping of the current protection device occurs, it may
be possible to operate the compressor from a 120 volt 20 amp circuit. See Figure 2.
Check motor data plate for 240 volt compatibility. A 240 volt unit must be operated on a 240 volt circuit. The cord
must only plug into a 240 volt grounded outlet and may require a new cord and plug. See Figure 3.
Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that accepts the plug
on the product. Make sure your extension cord is not damaged. When using an extension cord, be sure to use
one heavy enough to carry the current your product draws. For lengths less than 25 ft. 16-3 AWG extension
cords shall be used. An undersized cord results in a drop in the voltage and loss of power and overheating.
(NOTICE: Table below shows the correct size to use depending on cord length. When in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier the cord.)
Use of an extension cord may cause excess heat to motor. This could lead to tripped breaker (at electrical panel)
or tripped thermal overload (on compressor motor). If this occurs, eliminate extension cord and plug compressor
directly into electrical outlet. Avoid using extension cords; use longer air hose(s) instead.
Check with a qualified electrician or serviceman when the grounding instructions are not completely understood, or
when in doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the
outlet, have the proper outlet installed by a qualified electrician. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter with this product.

OPERATING INSTRUCTIONS
On/Off Cycling of Compressor
Risk of Bursting. Drain tank every day to prevent corrosion and possible injury due
to tank damage. Do not operate drain with more than 40 psi in tank or drain valve
may be damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.
Unit care and maintenance. Drain liquid from tank daily.
In the AUTO position, the compressor pumps air into
the tank. When a shut-off (preset “cut-out”) pressure is
reached, the compressor automatically shuts off.
If the compressor is left in the AUTO position and air
is depleted from the tank by use of a tire chuck, tool,
etc., the compressor will restart automatically at its
preset “cut-in” pressure. When a tool is being used
continuously, the compressor will cycle on and off
automatically.
In the OFF position, the compressor will not operate.
Drain Tank. Disconnect, tag, unplug and lock out power
source; release pressure. Drain moisture from tank by
opening drain valve underneath tank (See Figure 7).

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor pump.
When humidity is high or when a compressor is in continuous use for an extended period of
time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this
water will be carried from the tank through the hose, and out of the gun as droplets mixed
with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially when
spraying other than water based paints. If sandblasting, it will cause the sand to cake and
clog the gun, rendering it ineffective. A filter in the air line, located as near to the gun as
possible, will help eliminate this moisture.

MAINTENANCE AND INSPECTION INSTRUCTIONS
Disconnect, tag and lock out power source then release all pressure
from the system before attempting to install, service, relocate or perform any
maintenance.
In order to maintain efficient operation of the compressor system, check the air filter and oil level before each
use. The ASME safety valve should also be checked daily (see Figure 8). Pull ring on safety valve and allow the
ring to snap back to normal position. This valve automatically releases air if the tank pressure exceeds the preset
maximum. If air leaks after the ring has been released, or the valve is stuck and cannot be actuated by the ring,
the ASME safety valve must be replaced.

INSTALLATION
TROUBLESHOOTING OPERATION
Tank
Never attempt to repair or modify a tank! Welding, drilling or any other
modification will weaken the tank resulting in damage from rupture or explosion.
Always replace worn, cracked or damaged tanks.
Drain liquid from tank daily.
The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the welds. If a
crack is detected, remove pressure from tank immediately and replace.
Compressor Lubrication
See Installation. Add oil as required. The oil should be changed every three months or after every 200 hours of
operation; whichever comes first.
If the compressor is run under humid conditions for short periods of time, the humidity will condense in the
crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide adequate
lubrication and must be changed immediately. Using contaminated oil will damage bearings, pistons, cylinders
and rings and is not covered under warranty. To avoid water condensation in the oil, periodically run the
compressor with tank pressure near 120 psi for single stage compressors by opening the drain cock or an air
valve connected to the tank or hose. Run the pump for an hour at a time at least once a week or more often if the
condensation reoccurs.
IMPORTANT: Change oil after first 50 hours of operation.
Air Filter
Never run the compressor pump without an intake air filter or with
a clogged intake air filter. The air filter element should be checked
monthly (see Figure 9). Operating compressor with a dirty filter can
cause high oil consumption and increase oil contamination in the
discharge air. If the air filter is dirty it must be replaced.
