It may be necessary to brace or support one side of
the outfit when removing the shipping boards be-
cause the air compressor will have a tendency to
tip.

1.

Remove all packaging such that only the compressor on
the pallet remains. Remove and discard the (4) screws and
washers that hold the compressor to the pallet.

2.

Stationary air compressors must be bolted to the floor.
Bolting holes are provided in the base feet. Mount the air
compressor on a solid, level foundation. Support com-
pressor weight evenly on all four feet. Solid shims may be
used if necessary.

EXCESSIVE VIBRATION CAN WEAKEN THE AIR TANK
AND CAUSE AN EXPLOSION. THE COMPRESSOR
MUST BE PROPERLY MOUNTED AS ILLUSTRATED
BELOW.

Location of the Air Compressor

Locate the air compressor in a clean, dry and well ventilated
area. The air filter must be kept clear of obstructions which
could reduce air flow to the air compressor.  The air compressor
should be located at least 12" away from the wall or other
obstructions that will interfere with the flow of air. The air
compressor head and shroud are designed to allow for proper
cooling. If humidity is high, an air filter can be installed on the
air outlet adapter to remove excessive moisture. Follow the
instructions packaged with the air filter for proper installation.

Lubrication and Oil

This unit needs no lubrication or oiling.

Extension Cords

To avoid voltage drop, power loss, and overheating to the
motor, use extra air hose instead of an extension cord. Low
voltage can cause damage to the motor.
If an extension cord 

must

 be used:

• do not use with any permanently mounted air compressor.
• use only a 3-wire extension cord that has a 3-blade
grounding plug and a 3-slot receptacle that will accept

the plug on the extension cord.

• make sure the extension cord is in good condition.
• the extension cord should be no longer than 50 feet.
• the minimum wire size is 12 gauge (AWG). (Wire size

increases as gauge number decreases. 10 AWG and
8 AWG may also be used. DO NOT USE 14 AWG or
16  AWG.)

INSTALLATION AND BREAK-IN PROCEDURES

Certain air compressor models can be converted to
240 volts from 120 volt operation. When converting
a specific model to 240 volt operation, the attached
three-prong 120 volt plug must be replaced with
the three-prong 240 volt plug (purchase locally) or
order line cord Part No. K-0084.

Refer to Parts List  of your compressor. Certain air
compressor models can be operated on a 15 amp
circuit if:

1.

Voltage supply to circuit is normal.

2.

Circuit is not used to supply any other electri-
cal needs (lights, appliances, etc.).

3.

Extension cords comply with specifications
in this manual.

4.

Circuit is equipped with a 15 amp circuit
breaker or 15 amp time delay fuse. Use a
Fusetron Type "T" time delay fuse.

Some models have a dual voltage motor, 120 and 240 volt. They
are wired for 120 volt but can be converted to 240 volt operation.
Instructions for converting these motors for operation at 240
volt can be found printed on the label attached to the side of the
motor.

If any of the above conditions cannot be met, or if operation of
the compressor repeatedly causes interruption of the power, it
may be necessary to operate it from a 20 amp circuit. It is not
necessary to change the cord set.
