Drain Petcock - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily
to reduce the risk of corrosion.
Reduce tank pressure below 10 PSI,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank(s) by opening the drain
petcock located underneath the tank.
LUBRICATION
This is an oilless product and DOES
NOT require lubrication to operate.
IMPORTANT: Do not operate compres-
sor before reading instructions or
damage may result.
1. Turn switch to OFF position and plug
in power cord.
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 (MP3105), located as
near to the gun as possible, will
help eliminate this moisture.

5. Compressor will build to maximum
preset pressure and shut off.
6. Adjust regulator to proper pressure
for tool or tire. Operate tool per
instructions. Compressor will
automatically restart when pressure
in tank drops below cut-in pressure.
7. Turn regulator knob counterclock-
wise to shut off the air and turn
switch to Off position.
In the ON position, the compressor
pumps air into the tank. It shuts off
automatically when unit reaches its
maximum preset pressure. In the OFF
position, the compressor will not
operate. This switch should be in the
OFF position when connecting or
disconnecting the power cord from the
electrical outlet.

This valve should be checked
occasionally by pulling the ring by hand.
Air may leak even after ring has been
released. However, if the leaking

time, or if the safety valve is stuck and
cannot be activated by the ring, the
safety valve MUST be replaced. (Note:
Valve will reset when tank pressure
reaches 40-50 PSI.)

1. This knob controls air pressure to an
Off
air operated tool, or paint spray gun.

2. Turning knob clockwise increases air
pressure at outlet.
3. Turning counterclockwise will lower
air pressure at outlet.
4. Fully counterclockwise will shut off
flow of air completely.
OUTLET (TOOL) PRESSURE GAUGE
1. This gauge shows at-a-
glance, air pressure at
outlet. Air pressure is
measured in pounds per
square inch (psi).
2. Be sure this gauge reads ZERO before
changing air tools or disconnecting
hose from outlet.
TANK PRESSURE GAUGE
Gauge shows pressure in
tank indicating
compressor is building
pressure properly.
WARNING
!
Disconnect power source
then release all pressure
from the system before
attempting to install,
service, relocate or perform any
maintenance.
