Pressure Adjuster clockwise to increase the air output to the tool, up to the work-
ing air pressure (115 PSI) as indicated on the Tank Pressure Gauge (3A). Never
exceed the maximum PSI for the tool being used or any component of the air
system.
Turn the Tool Pressure Adjuster (2A) 2. counterclockwise to decrease the air output
to the tool.
To Use The Tank Pressure Relief Valve:
The Tank Pressure Relief Valve Ring (5A) is used when decompression is needed 1.
quickly and efciently. It is also designed to release automatically if the compres-
sor pressurizes up to or beyond it’s safe limit.
To decompress the Air Tank (9A) pressure, press the “ON/OFF” Power Switch (1A) 2.
down to turn off the Air Compressor.
Pull out on the Tank Pressure Relief Valve Ring (5A) to immediately release air 3.
pressure in the Air Tank (9A).
To Empty Moisture From The Tank:
The Water Drain Valve (10A) is located underneath the Air Tank (9A), and should 1.
be used daily to release all trapped moisture through this valve. If this is not done,
condensation may cause Air Tank corrosion. (See Assy. Diagram A.)
WARNING: Do not open the Water Drain Valve (10A) so that more than four threads are
showing.
Push down on the “ON/OFF” Power Switch (1A) to turn off the Air Compressor. 2.
Then, unplug the Air Compressor’s Power Cord from the electrical outlet.
You may wish to lay a pan under the drain to collect the dirty water trapped within. 3.
Slowly and carefully unscrew (no more than four threads) the Water Drain Valve
(10A) until the compressed air and condensation begins to be released from the Air
Tank (9A). Allow sufcient time for all of the air and condensation to escape from
the Air Tank. Then, rmly retighten the Water Drain Valve.
IMPORTANT!
IF THE MOTOR STOPS UNEXPECTEDLY, the overload breaker may have
sensed an over-current condition, and stopped the motor to protect it. If this oc-
curs, shut off the pressure switch and wait at least 5 minutes. Release the air pressure
in the tank to ease restarting. Then press the breaker button to reset it, and turn on the
pressure switch. To help prevent this, ensure that this compressor is set up on a dedi-
cated circuit (one with no other equipment running on it), and that the distance from the
compressor to the circuit breaker panel is as short as possible. Extension cords should
not be used, and the outlet should not be far from the panel.
