LUBRICATION
THIS UNIT IS
SHIPPED WITHOUT
OIL! Follow lubrication instructions
before operating compressor.
Ensure oil drain extension and cap has
been installed (if included) then remove
the dipstick breather (See Fig. 6) and fill
pump oil according to the chart.
See specification label on air tank for
pump model number and refer to the
chart for the proper oil capacity.
OIL
Use SAE 30 industrial grade air
compressor oil or full synthetic motor
oil like Mobil 1 10W30.
Do not use
regular automotive oil such as
10W-30.
Additives in motor oil can
cause valve deposits and reduce pump
life. For maximum pump life, drain and
replace oil after the first hour of run
time. Proper oil fill level is illustrated in
Figure 6.
For pumps with an oil sight glass, oil
level can be monitored and maintained
as shown in Figure 7.

CAUTION
Operation
START-UP
Do not attach air
tools to open end
of the hose until start-up is completed
and the unit checks OK.
Never disconnect
threaded joints
with pressure in tank!
1. Remove the breather and fill pump
to the proper oil level. See
lubrication section.
2. Open the tank drain valve. Turn
outlet valve to open air flow.
3. Move pressure switch lever or knob
to the OFF position and plug in
power cord. Move pressure switch
to the AUTO position to run the
unit.
4. Run the unit for 30 minutes, under
no load, to break in pump parts.
5. Move the pressure switch lever or
knob to OFF and turn tank drain
valve to shut off air flow. The
compressor is now ready for use.

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
Disconnect, tag and lock
out power source, then
release all pressure from
the system before attempting to install,
service, relocate or perform any
maintenance.
All repairs should be performed by an
authorized service representative.
FOR EFFICIENT OPERATION:
Perform the following test to verify free
operation of the safety valve weekly
and follow maintenance schedule.
1. Pull ring on safety valve and allow
the ring to snap back to normal
position (See Figure 9). This valve
automatically releases air if the tank
pressure exceeds the preset
maximum.
Do not attempt to
tamper with this
valve. This valve should be checked
occasionally. If air leaks after the ring
has been released, or the valve is stuck
and cannot be actuated by the ring, the
safety valve must be replaced.
A large amount of
fast moving air will
be released if this valve is actuated
with pressure in the tank.
2. With motor OFF and unplugged,
clean debris from motor, flywheel,
tank, air lines and pump cooling fins.
DRIVE BELT
Belts will stretch in normal use. Properly
adjusted, a 5-pound force applied to
the belt between the motor pulley and
the pump will deflect the belt about
1/2" (See Figure 10).
