How To Use Your Unit - Craftsman 919.165190 Owner's Manual

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.
If the overload protector shuts the
motor off frequently, check for a pos-
sible voltage problem, Low voltage
can also be suspected when:
1. The motor does not get up to full
power or speed.
2. Fuses blow out when starting
the motor; lights dim and remain
dim when motor is started and is
running.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"OFF".
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
after the unit reaches "cut-out" pres-
sure.

Valve
Motor Overload Protector: The
motor has an automatic reset thermal
overload protector. If the motor over-
heats for any reason, the overload
protector will shut off the motor. The
motor must be allowed to cool down
before restarting. The compressor
will automatically restart after the
motor cools,
Before First Start-up
_ Serious damage
may result if the
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 pro
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 (coun-
terclockwise) 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-
faces.
