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.
prESSUrE GaUGES
Gauge attached to regulator indicates
air pressure going to hose (and any
tool attached to end of hose). Gauge
attached to pressure switch indicates air
pressure in tank.
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.
1. Turn compressor off and release
pressure from system. To release
pressure from system, pull ring on
ASME safety valve (see Figures 6 and
8). 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 (see Figure
6) 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.
oIl CHanGE
1. Allow compressor to run and warm
up oil. Unplug unit.
2. Position a pan under pump end of
unit.
3. Remove oil drain plug (see Figure 6).
Allow oil to collect in pan. Tilt unit
to completely drain.
4. Replace drain plug, fill pump to
full line on 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.

Removal, Inspection and Replacement
(Figure 10)
figure 10 - Intake filter maintenance
Filter element
Filter cover
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. Rotate the filter cover counter
clockwise and remove .
2. Remove the filter element and
inspect.
3. If the filter element is dirty or
clogged, replace it.
4. Reinstall filter and cover.
IMportant
: Locate unit as far from
spraying area as hose will allow to
prevent overspray from clogging filter.
oVErloaD protECtor SECtIon
This compressor is
equipped with an
automatic reset overload protector
which will shut off motor if it becomes
overloaded.
If 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 overload
protector is
actuated, the motor must be allowed to
cool down for 30 minutes before it will
reset.
StoraGE
1. Drain tank of moisture.
2. When not in use, store compressor in
a cool, dry place.
3. Disconnect hose and hang open
ends down to allow any moisture to
drain.
