2 . Place lock washer on axle bolt. Then
tighten nut securely to threaded part
of axle bolt.

LUBRICATION
THIS UNIT IS
SHIPPED WITHOUT
O I L ! Follow lubrication instructions
before operating compressor.
Use oil shipped with the compressor.
Do not use regular automotive oil
such as 10W-30.
Additives in regular
motor oil can cause valve deposits and
reduce pump life. For maximum pump
life, drain and replace oil after the first
few hours of run time.
The compressor pump takes approxi-
mately 380 ml (13 ozs.) of oil. The sight
glass, located on the crankcase portion
of the pump, is marked with “max”
and “min” levels. Avoid overfilling by
adding oil gradually and checking the
oil level with the sight glass several
times. Add enough oil to reach the
“max” level on the sight glass. Proper
oil level is illustrated in Figure 3.
INTAKE FILTER
Thread the intake air filter into the
threaded opening in the side of the
compressor head as illustrated in
Figure 4. Tighten gently with a wrench.

L O C A T I O N
It is extremely important to install the
compressor in a clean, well ventilated
area where the surrounding air
temperature will not be more than
1 0 0 ° F .
A minimum clearance of 18 inches
between the compressor and a wall is
required because objects could obstruct
air flow.
Do not locate the
compressor air inlet
near steam, paint spray, sandblast areas
or any other source of contamination.
This debris will damage the motor.
ELECTRICAL INSTALLATION
All wiring and
e l e c t r i c a l
connections should be performed by a
qualified electrician. Installation must
be in accordance with local codes and
national electrical codes.
W I R I N G
1 . Local electrical wiring codes differ from
area to area. Source wiring, plug and
protector must be rated for at least the
amperage and voltage indicated on
motor nameplate, and meet all
electrical codes for this minimum.
2 . Use a slow blow fuse or a circuit
b r e a k e r .
3 . This product is for use on a nominal
120 volt circuit and has a grounding
plug that looks like the plug illustrated
in Figure 5. Make sure the product is
connected to an outlet having the
same configuration as the plug. This
product must be grounded. In the
event of an electrical short circuit,
grounding reduces risk of electrical
shock by providing an escape wire for
electric current. This product is
equipped with a cord having a
grounding wire with an appropriate
grounding plug. Plug must be plugged
into an outlet that is properly installed
and grounded in accordance with all
local codes and ordinances.
Overheating, short
circuiting and fire
damage will result from inadequate
w i r i n g .
