General Overview
Attaching an Air Hose
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
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.
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.
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. 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.
To increase air pressure, turn Air Regulator
clockwise.
To decrease air pressure, turn Air Regulator
counterclockwise.
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 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.
(See Figure 6)

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. Be
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.
7. Install the Oil Breather Cap into the Oil Fill hole.
Firmly hand tighten the Oil Breather Cap by
turning clockwise.
MAINTENANCE
Daily (or before each use)
1. Check oil level
2. Drain condensation from the air tank.
3. Check for any unusual noise or vibration.
4. Be sure all nuts and bolts are tight.
Weekly
1. Clean breather hole on Oil Breather Cap.
Monthly
1. Inspect air system for leaks by applying soapy
water to all joints. Tighten these joints if leaks
are discovered.
Always inspect the tool before use, and make sure
it is in good working condition. Make sure all air
vents are clear, (use compressed air to clean the
machine where possible). Check the power cable to
make sure it is intact and free from cracks, bare
wires etc. Avoid using solvents when cleaning
plastic parts. Most plastics are susceptible to
damage from the various types of commercial
solvents.
6 Months (or after 250 hours of operation -
whichever comes first)
1. Change Air Compressor Oil.
Note: Change oil more often if Air Compressor is
used near paint spraying operations or in dusty
environments.
Checking the Air Compressor Oil
1. Place Air Compressor on level surface. The oil
level should be at the red dot on the Oil Sight
Glass.
