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.

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.
Frequently
Risk of Unsafe
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 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.
