Operation (Continued)
7. Unplug power cord.
BEFORE EACH STARTUP
OPERATING PROCEDURE
1. Turn switch to OFF ( O ) position and
plug in power cord.
2. Turn regulator knob
counterclockwise to close air flow.
3. Turn switch to ON ( I ) position.
4. Compressor will build to maximum
pressure and shut off.
5. With hose attached to outlet of
compressor, attach tire chuck or
other tool to open end of hose.
6. Adjust regulator to proper pressure
for tool or tire. Operate tool per
instructions.
As air is depleted from the tank by use
of a tire chuck, tool, etc., the
compressor will restart automatically at
its preset “cut-in” pressure. When a
tool is being used continuously, the
compressor will cycle on and off
automatically.
7. Turn switch to OFF ( O ) position,
unplug power cord and drain tank of
air when finished using compressor.
Maintenance
Disconnect power source then
release all pressure from the
system before attempting to
install, service, relocate or perform any
maintenance. Service should be performed
by an authorized service representative.
The compressor should be checked
often for any visible problems and the
following maintenance procedures
should be performed each time the
compressor is used.
ASME SAFETY VALVE
Do not
remove or attempt to adjust the safety
valve!
Check the safety valve by performing
the following steps:
1. Plug the compressor in and run until
shut off pressure is reached (see
Operating Procedure).
2. Wearing safety glasses, pull the ring
on the safety valve to release
pressure from compressor tank. Use
your other hand to deflect fast-
moving air from being directed
toward your face.
3. The safety valve should automatically
close at approximately 40-50 PSI. If
the safety valve does not allow air to
be released when you pull on the
ring, or if it does not close
automatically, it MUST be replaced.
DRAIN TANK
With compressor shut off and pressure
released, drain moisture from tank by
opening drain valve underneath tank.
CLEANING
Turn power OFF and clean dust and dirt
from pump cover, tank, and air lines.
IMPORTANT: Unit should be located as
far from spraying area as hose will
allow to prevent over-spray from
clogging air filter.
LUBRICATION
This is an oilless type compressor
requiring no lubrication.
THERMAL OVERLOAD PROTECTOR
This
compressor
is equipped with an automatic reset
thermal overload protector which will
shut off motor if it becomes overheated.
If thermal overload protector shuts
motor OFF frequently look for the
following causes:
1. Low voltage
2. Lack of proper ventilation
If the
thermal
overload protector is actuated, the motor
must be allowed to cool down before
start-up is possible.
END OF OPERATION/STORAGE
1. Turn ON / OFF ( I / O ) switch to the
OFF ( O ) position.
2. Unplug power cord from wall outlet
and wrap around handle area to
prevent damage when not in use.
3. Wearing safety glasses drain tank of air
by pulling the ring on the safety valve.
Use other hand to deflect fast moving
air from being directed toward your
face.
4. Drain tank of condensation by
opening drain valve on bottom of
tank. Tank pressure should be below
10 psi when draining tank.
5. Air hose should be disconnected from
compressor and hung open ends
down to allow any moisture to drain.
6. Compressor and hose should be
stored in a cool, dry place.
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.
