Unit cycles
automatically
when
power is on. When performing
maintenance,
you may be exposed
to voltage sources, compressed
air, or moving parts. Personal
injuries can occur. Before
performing any maintenance
or
repair, disconnect
power source
from the compressor and bleed off
all air pressure.
To ensure efficient operation and
longer life of the air compressor
outfit, a routine maintenance
schedule should be prepared and
followed. The following
routine
maintenance schedule is geared to
an outfit in a normal working
environment operating on a daily
basis. If necessary, the schedule
should be modified to suit the
conditions
under which your
compressor
is used. The
modifications
will depend upon the
hours of operation and the working
environment.
Compressor
outfits in
an extremely dirty and/or hostile
environment will require a greater
frequency of all maintenance checks.
NOTE: See "Operation"
section for
the location of controls.

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 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.
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.
