Installing the Oil and Oil Breather Cap
Your air compressor is shipped without oil in the
crankcase. BEFORE STARTING THE AIR
COMPRESSOR YOU MUST ADD OIL TO THE
CRANKCASE AS DESCRIBED BELOW:
1. Place compressor on level ground.
2. Remove the Oil Shipping Plug from the Oil Fill
hole, located on the top of the crankcase cover
at the rear of the air compressor.
3. Slowly pour the oil into the Oil Fill hole, until the
oil level rises to the center of the red dot on the
Oil Sight Glass.
Note: This compressor uses only SAE 5W-30
motor oil.
WARNING! Tank Drain Valve should always be
opened slowly to avoid damage to equipment and
possible injury.
Air Filter: This heavy duty metal air filter keeps
your compressor running cleanly, by filtering out
impurities.
Oil Breather Cap: As the compressor motor
operates pressurized air must be released from the
crank case. The oil breather cap allows built up air
to escape, while shielding your air compressor from
airborne impurities.
Power Switch: The red tipped power switch turns the
air compressor on and off. When switch is in horizontal
position, compressor is turned ON. When switch is in
vertical position, compressor is turned OFF.

Cap section.)
Initial Start-Up Procedure
1. Open the Air Tank Drain Valve to permit air to
escape, preventing air pressure buildup in the
air tank.
2. Run the compressor for a minimum of 20
minutes in this “no-load” position to lubricate the
piston and bearings.
3. Close Air Tank Drain Valve. Your compressor is
ready for use.
Depending on the CFM draw of the tools being
operated, your new Air Compressor can be used for
operating paint sprayers, air tools, grease guns,
airbrushes, caulking guns, abrasive blasters, tire &
plastic toy inflation, spraying weed killer and
insecticides, etc. Proper adjustment of the Air
Pressure Regulator is necessary for all of these
operations. Refer to the air pressure specifications
provided with the tool you are using.
Figure 3. Installing the Air Chuck
Installing the Air Filter
The metal Air Filter is installed into the threaded
port of the cylinder head.
General Overview
To compress air, the piston moves up and down in
the cylinder. On the down stroke air is drawn in
through the valve inlet. The discharge valve remains
closed. On the upstroke of the piston air is
compressed. The inlet valve closes and air is forced
out through the discharge valve, through the check
valve, and into the air tank. Working air is not
available until the compressor has raised the tank
1. Thread the Air Filter into the Cylinder Head by
turning the Air Filter clockwise.
2. Securely tighten the Air Filter in place with a
wrench.

pressure above that required at the air service
connection. The air inlet filter openings must be
kept clear of obstructions, which could reduce air
delivery of the compressor.
To install an air hose, equipped with a 1/4" male
coupler:
1. Pull back on Air Chuck outer sleeve to allow
coupler to be fully inserted into Air Chuck.
2. Insert coupler into Air Chuck.
3. Release outer sleeve of Air Chuck.
4. Verify that air hose is securely connected to Air
Chuck by pulling lightly on air hose.
(See Figure 5)
Installation and Location
Locate the compressor in a clean, dry and well
ventilated area. The compressor should be located
12 to 18 inches from walls or any other obstruction
which would interfere with airflow. Compressor
should be located in a temperature controlled area
between 32° and 95° fahrenheit. Place the
compressor on a firm, level surface. The
compressor is designed with heat dissipation fins
which allow for proper cooling. Keep the fins (and
all other parts which collect dust or dirt) clean. A
clean compressor runs cooler and provides longer
service. Do not place rags, containers or other
material on top of the compressor.
Figure 5. Attaching an Air Hose
Adjusting the Air Pressure
Your Air Compressor is supplied with an Air
Pressure Regulator. This Regulator adjusts the air
pressure.
Connecting to Power Source
This air compressor is designed to operate on a
properly grounded 120 volt, 60Hz, single phase,
alternating current (ac) power source with a fused
20 amp time delayed fuse or circuit breaker. It is
recommended that a qualified electrician verify the
ACTUAL VOLTAGE at the receptacle into which the
unit will be plugged and confirm that the receptacle
is properly fused and grounded. The use of the
proper circuit size can eliminate nuisance circuit
breaker tripping while operating your air
To increase air pressure, turn Air Regulator
clockwise.
To decrease air pressure, turn Air Regulator
counterclockwise.

compressor.
Extension Cords
For optimum Air Compressor performance an
extension cord should not be used unless
absolutely necessary. If necessary, care must be
taken in selecting an extension cord appropriate for
use with your specific Air Compressor. Select a
properly grounded extension cord which will mate
directly with the power source receptacle and the
Air Compressor power cord without the use of
adapters. Make certain that the extension cord is
properly wired and in good electrical condition.
Maximum length of extension cord should be 50
feet. Minimum wire size of extension cord should be
12 gauge.
Figure 6. Adjusting the Air Pressure
Cold Weather Starting
Temperatures below freezing (32°F) cause the
metal parts of your Air Compressor to contract and
that makes starting more difficult. To assist the Air
Compressor in starting in cold weather, follow
these tips:
1. Try to keep Air Compressor stored in
temperatures above 32° fahrenheit.
2. Open the Air Tank Drain Valve and release all
air pressure from the Air Tank before attempting
to start in cold weather. (After air is released
from Air Tank, close Drain Valve.)
3. Plug Air Compressor directly into a 120 volt
electrical outlet. Do not use an extension cord
when starting your Air Compressor in cold
weather.
Attaching an Air Hose
Your Air Compressor is supplied with a 1/4" Quick
Disconnect Air Chuck. Once you have correctly
installed the Air Chuck (See Installing the Air Chuck
on p.4) your compressor will be ready to accept air
hoses equipped with 1/4" male air couplers.
Note: Use only air hoses rated for use with 115psi
air pressure or higher.

Changing the Air Compressor Oil
Note: This compressor uses only SAE 5W-30
motor oil.
1. Remove the Drain Plug under the Oil Sight
Glass by turning the nut counter-clockwise with
wrench. (See Figure 2.)
Note: Oil will begin to drain as Drain Plug is
loosened. Place a funnel and oil pan in place
BEFORE loosening Drain Plug.
2. Once Drain Plug is removed, tilt Air Compressor
backwards to allow all of the oil to drain out of
the crankcase.
3. Once oil is drained, replace Drain Plug and
securely tighten in place with a wrench. B
careful not to overtighten the Drain Plug, as this
could damage the rubber seal.
4. Place Air Compressor on level surface.
5. Remove the Oil Breather Cap.
6. Slowly pour the oil into the oil fill hole, until the
oil level rises to the center of the red dot on the
Oil Sight Glass.
