COMPRESSOR CONTROLS

Refer to Fig. 3.

I WARNING

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.
