How to Start:

1.

Turn the On/Auto/Off lever to "AUTO" and allow tank pressure to build.
Motor will stop when tank pressure reaches "cut-out" pressure.

2.

Pull the regulator knob out and turn clockwise to increase pressure. When
the desired pressure is reached push knob in to lock in place. The
compressor is ready for use.

NOTE: Always operate the air compressor in well-ventilated areas free of
gasoline or other combustible vapors. If the compressor is being used to
operate a sprayer DO NOT place near the spray area.

Before Each Start-Up:

1.

Place On/Auto/Off lever to "OFF".

2.

Pull regulator knob out, turn counter-clockwise until it stops. Push knob in
to lock in place.

3.

Attach hose and accessories. NOTE: The hose or accessory will require a
quick connect plug if the air outlet is equipped with a quick connect.

Too much air pressure causes a hazardous risk of

bursting. Check the manufacturer’s maximum pressure

rating for air tools and accessories. The regulator outlet pressure must
never exceed the maximum pressure rating.

6.

After 15 minutes, close the drain valve (clockwise). The air receiver will fill
to "cut-out" pressure and the motor will stop.

The compressor is now ready for use.
