Air Compressor Pump: 

 To compress air, the piston

moves up and down in the cylinder.  On the downstroke,
air is drawn in through the air intake muffler (valves).  The
exhaust valve remains closed.  On the upstroke of the
piston, air is compressed.  The intake valves close and
compressed air is forced out through the exhaust valve
and then through the air hose.

Adjustable Pressure Valve:

  The pressure valve controls

the amount of pressure going from the air compressor to
the accessory. The pressure adjusting valve can be used
to set approximate pressure between 10 and 125 P.S.I.
(125 P.S.I. is the highest pressure this compressor will
deliver). It is normal for the adjustable pressure valve to
release air during operation.

DESCRIPTION OF OPERATION

ALWAYS SET THE PRESSURE VALVE AT OR BE-
LOW THE REQUIRED PRESSURE FOR THE AC-
CESSORY BEING USED BEFORE STARTING YOUR
COMPRESSOR. FOR INFLATION OR OTHER USES
REQUIRING ACCURATE PRESSURE, USE A PRES-
SURE GAUGE.

NSTALLATION AND BREAK-IN PROCEDURES

Location of the Air Compressor

Your compressor comes to you completely assembled
and ready for use.  Operate the air compressor in a dry,
clean, cool and well ventilated area.  The air compressor
pump and case are designed to allow for proper cooling.
Clean or blow off dust or dirt that collects on the air
compressor.  A clean air compressor runs cooler and
provides longer service.  The ventilation openings on your
air compressor are necessary to maintain proper operat-
ing temperature.  Do not place rags or other containers on
or near these openings.

Extension Cords

Use extra air hose instead of an extension cord to avoid
voltage drop and power loss to the motor. Low voltage can
cause damage to the motor.

If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade grounding

plug, and a 3-slot receptacle that will accept the plug on
the compressor

• in good condition
• no longer than 50 feet
• 14 gauge (AWG) or larger.  (Wire size increases as gauge

number decreases.)  12 AWG, 10 AWG and 8 AWG may
also be used.  DO NOT USE 16 OR 18 AWG.

GROUNDING  INSTRUCTIONS

RISK OF ELECTRICAL SHOCK! In the event of a
short circuit, grounding reduces the risk of shock
by providing an escape wire for the electric
current. This air compressor must be properly
grounded.

The air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug. The
plug must be used with an outlet that has been installed
and grounded in accordance with all local codes and
ordinances. The outlet must have the same configuration
as the plug. See illustration. 

DO NOT USE AN

ADAPTER.

Inspect the plug and cord before each use. Do not use if
there are signs of damage.

IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.
