Prior to Starting

Caution!

This instruction manual should be

readily available to all operators and

maintenance personnel. If any part

of the manual become illegible or

the manual is lost, have it replaced

immediately. The instruction manual

should be reviewed periodically to

prevent a serious accident.

Before starting the compressor, review

Sections II and III of this manual. Be certain

that all installation requirements have

been met and that the purpose and use of

the controls are thoroughly understood.

Before placing the compressor into

operation, do the following:

• Remove all loose items and tools from

around the compressor.

• Check fluid level in the air/fluid

reservoir. See Compressor Fluid

Section.

• Check the fan and fan mounting for

tightness.

• Manually rotate the compressor

through enough revolutions to be

certain there are no mechanical

interferences.

• Check all pressure connections for

tightness.

• Check to make sure all relief valves are

in place.

• Check to make sure all panels and

guards are in place and securely

mounted.

• Check fuses, circuit breakers and

thermal overloads for proper size.

• Close the main power disconnect

switch and jog the starter switch button

to check the rotational direction of the

compressor.

• Check the fan rotation (air flows

through the coolers).

• Water-cooled models - Check inlet

and discharge water piping for proper

connections.
