Compressor
Basic Compressor Components
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 switch restarts the motor automatically,
without warning, and the pump resumes compressing air.
Assembling the Air Compressor
Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged
in transit, contact the carrier and complete a damage claim. Do this immediately
because there are time limitations to damage claims. The carton should contain.

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).
