Operation (Continued)
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 (see Figures 4 and
8) 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.
PRESSURE GAUGES
Gauge attached to the left of the
regulator indicates air pressure going
to hose (and any tool attached to end
of hose).
Gauge attached to the right of the
regulator 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 4 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 4) 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 4).
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.
5. Change oil after every 50 hours of
use.
INTAKE AIR FILTER MAINTENANCE
Removal, Inspection and Replacement
(Figure 10)
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 a manual
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 manual resetting. The motor
reset is located on the side of the
compressor pump (see Figure 4).
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.
