Speedaire Operating Instructions and Parts Manual 5Z598C
STOPPING
1. Set the OFF/AUTO lever to OFF.
2. Turn the regulator counterclockwise
and set the outlet pressure to zero.
3. Remove air tool or accessory.
4. Open regulator and allow air to
slowly bleed from the tank. Close
regulator when tank pressure is
approximately 20 psi.
5. Drain water from air tank.
Water will
condense in air
tank. If not drained, water will
corrode and weaken air tank causing
a risk of air tank rupture.
With tank pressure at approximately
20 psi, open the drain valve and tip the
outfit allowing all moisture to drain.
NOTE: If drain valve is plugged, release
all air pressure. Remove valve, clean,
then reinstall valve.
6. After water has been drained, close
drain valve. Air compressor can now
be stored.
Operation (Continued)
OUTLET PRESSURE GAUGE
The outlet pressure gauge indicates the
air pressure available at the outlet side
of the regulator. Pressure is controlled
by the regulator and is always equal to
or less than the tank pressure. See
"Operating Procedures."
TANK PRESSURE GAUGE
The reserve air pressure in the tank is
indicated by the tank pressure gauge.
OPERATING PROCEDURES
STARTING
1. Before attaching air hose or
accessories, make sure the OFF/
AUTO lever is set to OFF and the
air regulator is closed. (Turn
counterclockwise to close.)
2. Attach hose and accessories.
Incorrect use can
cause bursting, fire
or explosion hazards. Carefully
follow steps 3, 5, and 6 each time
the compressor is used.
3. Check manufacturer's maximum
pressure rating for air tools and
accessories. Regulator outlet
pressure must never exceed the
maximum pressure rating.
4. Turn OFF/AUTO lever to AUTO and
allow tank pressure to build. Motor
will stop when tank pressure
reaches "cut-out" pressure.
5. Open regulator by turning it
clockwise. Adjust the regulator to
the correct pressure setting.
Compressor is now ready for use.
6. Always operate air compressor in
well-ventilated areas (free of
gasoline, flammable paint or solvent
vapors). Do not operate the
compressor near a spray area.
Maintenance
Unit cycles
automatically
when power is on. When
preforming maintenance, you may
be exposed to voltage sources,
compressed air or moving parts.
Before performing any maintenance
or repair, unplug the power cord
and bleed off all air pressure.
AIR FILTER INSPECTION
NOTE: Keep the air filter clean at all
times. Do not operate the compressor
with the air filter removed. A dirty
filter will not allow the compressor to
operate at full capacity. Before using
the compressor, check the air filter to
be sure it is clean. To remove and clean
(wash in mild detergent) or replace the
foam air filter, compress the rear
slotted end of each of the two pins
holding filter in place and pull pin
MOTOR
Motor has an automatic reset thermal
overload protector. If motor overheats
for any reason, overload protector will
shut off motor. Motor must be allowed
to cool down before restarting. Com-
pressor will automatically re-start after
motor cools:
Low voltage may cause:
1. Overload protector to frequently
shut off the motor.
2. Motor not to get up to full power or
speed.
3. Fuses to blow out when starting the
motor.
4. Lights to dim and remain dim when
motor is started and running.
Speedaire Portable Air Compressor ®
forward releasing the filter itself. To
reinstall a clean filter, place in position
and push retaining pins into holes
securing filter.
NOTE: Wire support screen supplied in
the replacement parts kits, to be
positioned behind the foam filter, is not
required on the 3/4 HP model.
LUBRICATION
Compressor does not require any
lubrication. All metal bearings are
permanently lubricated and the com-
pression cylinder/piston/ring area is
specifically designed to require no
lubrication.
SAFETY VALVE - INSPECTION
If safety valve does
not work properly,
over-pressurization may occur,
causing air tank rupture or an
explosion. Occasionally pull ring on
safety valve to make certain safety
valve operates freely. If the valve is
stuck or does not operate smoothly,
replace with the same type of valve.
