Maintenance
Disconnect power source and
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.
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.
Safety valve must
be replaced if it
cannot be actuated or it leaks air after
ring is released.
A large amount of
fast moving air will
be released when the safety valve is
opened with pressure in the tank. Wear
ANSI approved Z87.1 safety glasses.
DRaIn tank
With compressor shut off and pressure
released, drain moisture from tank by
opening drain valve underneath tank
(See Figure 5).
CLeanInG
Turn power OFF and clean dust and dirt
from motor, tank, air lines and pump
cooling fins.
IMPORtant:
Unit should be located as
far from spraying area as hose will allow
to prevent over-spray from clogging air
filter.
OIL ChanGe
1. Allow compressor to run and warm
up oil. Unplug unit.
2. Position a pan under pump end of
unit.
3. Remove drain plug (see Figure 1).
Allow oil to collect in pan. Tilt unit
to completely drain.
4. Replace drain plug, fill pump to
center of sight glass. Use Chevron
synthetic 5W-30, Mobil 1 5W-30 or
10W-30 synthetic motor oil. Using
other types of oil will cause starting
problems.
5. Change oil after every 50 hours of
use.

Removal, Inspection and Replacement
(Figure 6)
The intake filter element should be
removed and checked periodically.
A clogged intake filter can decrease
compressor performance and cause the
compressor to overheat.
1. Gently pry filter cover from housing.
2. Remove the filter element and
inspect.
3. If the filter element is dirty or
clogged, clean with hot, soapy water
or replace if necessary.
4. Reinstall filter and cover.
IMPORtant:
Locate unit as far from
spraying area as hose will allow to
prevent overspray from clogging filter.
enD OF OPeRatIOn/stORaGe
1. Turn AUTO/OFF switch to the OFF
position.
2. Unplug power cord from wall outlet
and wrap around handle 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.
