Oilless Compressors
Operation
(Continued)
ASME SAFETY VALVE
Do not remove or
attempt to adjust
the safety valve!
Figure 3
Check safetly valve under pressure daily
by pulling the ring by hand. If air leaks
after ring has been released, or valve is
stuck and cannot be actuated by ring, it
MUST be replaced.
REGULATOR KNOB
1. This knob controls air pressure to an
air operated tool or paint spray gun.
2. Turn knob clockwise to increase air
pressure.
3. To lower air pressure turn knob
counterclockwise.
4. Turn fully counterclockwise to shut
off flow of air completely.
Maintenance
Disconnect power
source then release all
pressure from the
system before
attempting to install, service, relocate
or perform any maintenance.
Check compressor often for any visible
problems and follow maintenance
procedures each time compressor is
used.
1. Pull ring on safety valve and allow it
to snap back to normal position.
Safety valve must
be replaced if it
cannot be actuated or it leaks air after
ring is released.
2. Turn compressor off and release
pressure from system. Drain moisture
from tank by opening drain cock
underneath tank. Tilt tank to
remove all moisture.

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.

3. Clean dust and dirt from motor, tank,
air lines and pump cooling fins while
compressor is still OFF.
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. Clogged air filter.
3. Lack of proper ventilation.
If the thermal
overload protector
is actuated, the motor must be allowed
to cool down before start-up is possible.
The motor will automatically restart
without warning if left plugged into
electrical outlet and unit is turned on.
STORAGE
1. When not in use, store hose and
compressor in a cool dry place.
2. Drain tank of moisture.
3. Disconnect hose and hang open ends
down to allow any moisture to drain.
