Craftsman 919.72458 Air Compressor User Manual


 
Before Starting
Break-in instructions
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
prevent air from escaping through the
quick connect.
2.
Plug the power cord into the
correct branch circuit receptacle.
(Refer to Voltage and Circuit
Protection paragraph in the
Installation section of this
manual.)
3. Open the drain valve fully
(counter-clockwise) to permit air
to escape and prevent air
pressure build up in the air tank
during the break-in period.
4. Move the On/Auto/Off lever to
"ON/AUTO" position. The
compressor will start.

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:
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.
Drain Valve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
Check Valve: When the air
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 continuous
leaking after unit reaches "cut-out"
pressure.
