Oilless Compressors

Operation (Continued)
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.
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!
Figure 5
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.
Figure 6
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
a 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.
lUbrICatIOn
1. Turn ON / OFF switch to the OFF
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.
