COMPRESSOR CONTROLS

Refer to Fig. 3.
WARNING
I
For your safety, tank pressure is preset within the
switch and must never be tampered with.
Pressure Switch (see A)
This switch must not be adjusted by the operator; doing so will void the
warranty. The pressure switch controls the level of air pressure in the tank
by automatically starting and stopping the motor, as required to maintain the
factory preset pressure level.
The pressure switch also automatically bleeds pressure from the pump head
when the pump stops. This feature eliminates back pressure in the pump,
ensuring easier starting.
Pressure Relief Valve (see B)
If the pressure switch does not shut down the motor when pressure reaches
the preset level, this valve will pop open automatically to prevent over
pressurization. To operate manually, pull the ring on the valve to relieve air
pressure in the tank.
Tank Pressure Gauge (see C)
This gauge measures the pressure level of the air stored in the tank. It is not
adjustable by the operator, and does not indicate line pressure.
