Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart
of this cooling system is an engi-
neered fan. It is perfectly normal for
this fan to blow air through the vent
holes in large amounts. You know
that the cooling system is working
when air is being expelled.
Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.
Check Valve: When the air compres-
sor is operating, the check valve is
"open", allowing compressed air to
enter the air tank. When the air com-
pressor reaches "cut-out" pressure,
the check valve "closes", allowing air
pressure to remain inside the air tank.
Check Valve
Pressure Release Valve: The pres-
sure release valve located on the side
of the pressure switch, is designed to
automatically release compressed air
from the compressor head and the
outlet tube when the air compressor
reaches "cut-out" pressure or is shut
off. The pressure release valve allows
the motor to restart freely. When the
motor stops running, air will be heard
escaping
from this
valve for a
few seconds.
No air should
be heard
leaking when
the motor is
running, or
continuous
leaking after unit reaches "cut-out"
pressure.

How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"OFF".
Before Starting
Break-in instructions
following break-in instructions are
not closely followed.
This procedure is required before the
air compressor is put into service and
when the check valve or a complete
compressor pump has been
replaced.
1. Make sure the On/Auto/Off lever
is in the "OFF" position.
NOTE: If quick connect is installed,
pull coupler back until it clicks to pre-
vent air from escaping through the
quick connect.
2. Plug the power cord into the cor-
rect branch circuit receptacle.
(Refer to Voltage and Circuit
Protection paragraph in the
Installation section of this manu-
al.)
3. Open the drain valve fully (count-
er-clockwise) to permit air to
escape and prevent air pressure
build up in the air tank during the
break-in period.
NOTE: Always drain tank on a wash-
able surface or in a suitable container
to prevent damaging or staining sur-
Pressure
faces.
