How To Use Your Unit - Craftsman 919.167220 Owner's Manual

Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart
of this cooling system is an
engineered 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
Check Valve
compressor
is operating,
the check
valve is
"open",
allowing
compressed air to enter the air tank.
When the air compressor reaches
"cut-out" pressure, the check valve
"closes", allowing air pressure to
remain inside the air tank.
Pressure Release Valve: The
pressure 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
after the unit
reaches "cut-
out"
pressure.

Open the drain valve fully
(counterclockwise) to permit air
to escape and prevent air
