Craftsman 919.7247 Air Compressor User Manual


 
14- ENG
D24563
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
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.
Air Intake Filter (not shown): This
filter is designed to clean air coming
into the pump. This filter must always
be clean and ventilation openings
free from obstructions. See
"Maintenance".

Before Starting
Break-in Procedure
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.

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.
