Operation. Unit
cycles automatically
when power is
on. When servicing, you may be
exposed to voltage sources,
compressed
air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to the
air compressor, bleed tank of
pressure, and allow the air
compressor to cool.
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
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
units 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.
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.
To Drain Tank
1.
Set the On/Auto/Off
lever to
"OFF".
2.
Pull the regulator knob out and
turn counterclockwise
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.
