BASIC AIR COMPRESSOR COMPONENTS

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 (see Fig. 1).
The electric motor (see A) powers the pump. The electric
motor is equipped with an overload protector to help prevent
possible motor burnout. If the motor becomes overheated, the
overload protector will shut it down. Should this occur, allow the
motor to cool for 10-15 minutes, then press (never force) the
motor reset switch to restart the motor.
The pump (see A) compresses the air and discharges it into
the tank.
The tank (see B) stores the compressed air.
The pressure switch (see C) shuts down the motor when
the tank reaches a pre-set "cut-out" pressure. As compressed air
is used and the tank drops to a pre-set "cut-in" pressure, the
switch restarts the motor automaticallly, and the pump resumes
compressing air.

ASSEMBLING THE COMPRESSOR

1. 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:
• air compressor
• operator/parts manual
2. Check the compressor's serial label to ensure that you
have received the model ordered, and that it has the
required pressure rating for its intended use.
3. Locate the compressor according to the following
guidelines:
a. Position the compressor near a grounded electrical
outlet (see GROUNDING INSTRUCTIONS). Avoid
using an extension cord; use a longer air hose instead.
b. The pump side of the compressor must be at least
12 inches (31 cm) from any wall or obstruction, in a
clean, well-ventilated area, to ensure sufficient air
flow and cooling.
c. In cold climates, store portable compressors in a
heated building when not in use. This will reduce
problems with lubrication, motor starting and freezing
of water condensation.
d. The compressor must be level to ensure drainage of the
moisture in the tank.
4. Connect an air hose (not included) to the quick connect (D).
