Drain Valve (I): The drain valve is
located at the base of the air tank and is
used to drain condensation at the end of
each use.
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 over the pump head, cylinder sleeve, and crankcase. You know 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.
Dipstick (J): Indicates the amount of oil in the pump, the
+ mark indicates full and the - mark indicates oil needs to
be added. See Oil paragraphs in the Maintenance section
for instructions.
Motor Thermal Overload Protector (not shown): The
motor has an automatic reset thermal overload protector.
If the motor overheats 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.
Air Intake Filter (K): 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".
Check Valve (L): 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 (M): 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.
