7.
Connect the air hose (not provided) to the previously installed 3/8" NPT Quick
Coupler on the Air Outlet Line. Then, connect the other end of the air hose to the
pneumatic tool or equipment (not provided) that is to be used.
8.
Start the Gasoline Engine (5). Refer to the Gasoline Engine manufacturer's
instruction manual for further information.
9.
Allow sufficient time for the Air Tanks' Pressure Gauge (27) to indicate at least 80
PSI before using the Air Compressor. (See Figure I.)

Turn the Control Valve Assembly (22) counterclockwise to allow air to the
pneumatic tool. (See Figures B, and E.)
11.
NOTE: When adjusting the air pressure being forwarded to the pneumatic tool,
you will need to compare the pressure readings of both the Tanks' Pressure
Gauge (27) and the outlet Pressure Gauge (44). The reading on the Tanks'
Pressure Gauge dictates the maximum air pressure at which the outlet Pressure
Gauge may be set. (See Figure E.)
12.
With the Air Compressor running, and the air hose and pneumatic tool hooked up
to the Air Compressor, turn the Control Valve Assembly (22)
counterclockwise to increase the air output to the tool, up to the maximum rated
pressure (115 PSI) as indicated on the Tanks' Pressure Gauge (27). (See Figure
E.) In any case never exceed the pressure rating of the hose or tool connected to
compressor.
13.
Turn the Control Valve Assembly (22) clockwise to decrease the air output to the
tool, down to the minimum rated pressure (0 PSI) as indicated on the Tanks'
Pressure Gauge (27). (See Figure E.)
14.
The Safety Valve (42) is used when decompression is needed quickly and
efficiently. (See Figure B.)
