NOTE: See "Operation" section for
the location of controls.
To ensure efficient operation and
longer life of the air compressor out-
fit, a routine maintenance schedule
should be prepared and followed.
The following routine maintenance
schedule is geared to an outfit 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 outfits in an
extremely dirty and/or hostile environ-
ment will require a greater frequency
of all maintenance checks.
Unit cycles auto-
matically when
power is on. When performing
maintenance, you may be exposed
to voltage sources, compressed
air, or moving parts. Personal
injuries can occur. Before perform-
ing any maintenance or repair, dis-
connect power source from the
compressor and bleed off all air
pressure.
To Check Safety Valve
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.

To Drain Tank
1. Set the On/Auto/Off lever to
"OFF”.
2. Pull the regulator knob out and
turn clockwise 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.
Water will con-
dense in the air
tank. If not drained, water will cor-
rode and weaken the air tank caus-
ing a risk of air tank rupture.
