(See Figure E.)
To Start The Air Compressor:
Plug the Power Cord Plug (31) into the nearest 240 volt, grounded, electrical out-
1.
let.
Rotate the Power Switch Lever (9) up to its
2.
“ON” position. (See Figure E.)
Turn the Pressure Adjustment Knob (6)
3.
clockwise about halfway to its
“ON” posi-
tion.
(See Figure E.)
Allow sufficient time for Tank Pressure Gauge (5A) to indicate at least
4.
80 PSi.
(See Figure E.)
Check to make sure the pneumatic tool which will be used is turned off and prop-
5.
erly connected to air hose.
Once the Tank Pressure Gauge (5A) has reached at least 80 PSI, turn the Lever

(See Figure E.)
If necessary, turn the Pressure Adjustment Knob (6)

designed to automatically shut off the Air Compressor in the event its Motor (14)
becomes overheated.
(See Figure E.)
Should the Air Compressor automatically shut off at a pressure less than 115 PSI,
2.
rotate the Power Switch Lever (9) down to its
“OFF” position. (See Figure E.)
