Check Safety Valve
Drain Tank
NOTE: See "Operation" section for
the location of controls.
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 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.
6. After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, the
reinstalled.
