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 lon-
ger life of the air compressor, a rou-
tine maintenance schedule should be
prepared and followed. The following
routine
maintenance schedule is
geared to a unit in a normal working
environment operating on a daily ba-
sis. 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 work-
ing 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.
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 compres-
sor, 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" 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 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.
