Maintenance
Disconnect, tag and lock out
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.
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.
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 psi - 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.
DraIn tank
1. Turn compressor off and release
pressure from system. (To release
pressure from system, pull ring on
ASME safety valve. Deflect escaping
air by shielding valve with one hand
as you pull ring with other hand.)
Pull ring until tank is empty.
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.
2. Drain moisture from tank by
opening drain valve underneath
tank. Tilt tank to remove all
moisture.
3. Clean dust and dirt from tank,
air lines and pump cover while
compressor is still OFF.
Intake aIr FIlter MaIntenanCe
Removal, Inspection and Replacement
(Figure 8).
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. Remove bolt.
2. Remove the filter cover and filter
element. Inspect each piece.
3. If the filter element is dirty or
clogged, replace it.
4. Reinstall filter, cover, and bolt.
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.
