To Drain Tank
1. Set the On/Auto/Off lever to "Off"
and unplug unit.
2. Turn the regulator knob counter-
clockwise to set the outlet
pressure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately
20 psi. Release safety valve ring.
5. Drain water from air tank by
opening drain valve (counter-
clockwise) on bottom of tank.
Risk of Bursting.
Water will
condense in the air tank. If not
drained, water will corrode and
weaken the air tank causing a risk
of air tank rupture.
6. After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, the
reinstalled.
To Check Safety Valve
Risk of Bursting.
If the safety valve
does not work properly, over-
pressurization may occur, causing
air tank rupture or an explosion.
1. Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve
is stuck or does not operate
smoothly, it must be replaced
with the same type of valve.

pump intake and exhaust valves.
Air Filter Inspection and
Replacement
Hot surfaces.
Risk of burn.
Compres-sor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
Keep the air filter
clean at all times.
Do not operate the air compressor
with the air filter removed.
A dirty air filter will not allow the
compressor pump to operate at
full capacity. Before you use the
compressor pump, check the air filter
to be sure it is clean and in place.
If it is dirty, replace it with a new filter.
1. Remove the air filter cover.
2. Remove the air filter from filter
cover.
3. Place new air filter into filter
cover. Refer to the "Repair Parts"
for the correct part number.
4. Replace air filter cover and lock
into place.
