OVERVIEW
Oilless air compressors are factory lubricated for life and do not require any oil.
The basic components of the air compressor are the electric motor, pump,
pressure switch, and tank. (Figure 1)
The electric motor (A) powers the pump. The electric motor is equipped with an
overload protector and an automatic reset. If the motor becomes overheated,
the overload protector will shut it down to prevent damage to the motor.
The motor must be allowed to cool down before restarting. To reset the motor
overload toggle turn the pressure switch AUTO/OFF lever to the OFF position
and unplug the unit from the power outlet. Allow 10 minutes (minimum) for motor
overload cut-out to cool and reset. Unit can then be plugged in and re-started.
The pump (B) compresses the air and discharges it into the tank.
The tank (C) stores the compressed air.

tank reaches the cut–out pressure.

As compressed air is used and the
pressure level in the tank drops to the
cut–in pressure, the pressure switch
restarts the motor automatically,
without warning, and the pump
resumes compressing air.
