To ensure efficient operation and
longer life of the air compressor unit,
a routine maintenance schedule
should be prepared and followed.
The following routine maintenance
schedule is geared to an unit in a
normal working environment operat-
ing on a daily basis. If necessary, the
schedule should be modified to suit
the conditions under which your
compressor is used. The modifica-
tions will depend upon the hours of
operation and the working environ-
ment. Compressor units in an
extremely dirty and/or hostile environ-
ment will require a greater frequency
of all maintenance checks.

To Drain Tank
1. Set the On/Auto/Off lever to
“OFF” and unplug unit.
2. Pull the regulator knob out and
turn counterclockwise to set the
outlet pressure to zero.
3. Remove the air tool or accesso-
ry.
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 con-
dense in the air tank. If not
drained, water will corrode and
weaken the air tank causing a risk
of air tank rupture.
Frequently
Risk of Unsafe
Operation. Unit
cycles automatically when power is
on. When servicing, you may be
exposed to voltage sources, com-
pressed air, or moving parts.
Before servicing unit unplug or dis-
connect electrical supply to the air
compressor, bleed tank of pres-
sure, and allow the air compressor
to cool.
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.
