Compressor (cont’d)
Basic Air Compressor Components
Oil-less aircompressor are factory
lubricated for life and do not require
any oil.
The basic components of the air
compressor the electric motor,
pump, pressure switch, and tank.
The electric motor (see 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. When the motor
sufficiently cools, it will automatically
restart.
The pump (see B) compresses the air
and discharges it into the tank.
The tank (see C) stores the compressed
air.
The pressure switch (located internally) shuts down the motor and relieves air
pressure in the pump and transfer tube when the air pressure in the tank reaches
the kick-out pressure. As compressed air is used and the pressure level in the
tank drops to the kick-in pressure, the pressure, the pressure switch restarts
the motor automatically, without warning, and the pump resumes compressing air.
Assembling the Air Compressor

Electrical Power Requirements
Electrical Wiring
Refer to the air compressor’s serial label for the unit’s voltage and amperage
requirements. Use a dedicated circuit. For best performance and reliable starting, the
air compressor must be plugged into a dedicated circuit, as close as possible to the
fuse box or circuit breaker. The compressor will use the full capacity of a typical
15 amp household circuit. If other devices are on the same circuit, the compressor
may fail to start. Low voltage or an overloaded circuit can result in sluggish starting
that causes the motor overload protection system circuit breaker to trip, especially in
cold conditions.
Note: A circuit breaker is recommended. If the air compressor is connected to
a circuit protected by a fuse, use dual element time delay fuses (Buss Fusetron type“1”
only).
Note: Avoid use of extension cords. If using an extension cord is necessary,
be sure to use an extension with the correct specifications.
For optimum performance, plug the compressor power cord directly into a grounded
wall socket. Do not use an extension cord unless absolutely necessary. Instead, use a
longer air hose to reach the area where the air is needed.
If use of an extension cord cannot be avoided, the cord should be no longer than 100
feet and be a minimum wire size of 14 gauge (AWG).
