BASIC AIR COMPRESSOR COMPONENTS
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 B) compresses the air and discharges it into the
tank.
The tank (see C) stores the compressed air.
The pressure switch (see D) 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
ASSEMBLING THE COMPRESSOR
This compressor was shipped with oil in the pump crankcase.
Check oil before operating the air compressor, see Check Oil
under Maintenance.
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 hose instead.
Pressure Switch (see A)
This switch turns on the compressor. It is operated manually, but
when in the AUTO position, it allows the compressor to start up or shut
down automatically, without warning, upon air demand. ALWAYS set
this switch to OFF when the compressor is not being used, and before
unplugging the compressor.
Tank Safety Valve (see B)
Used to allow tank pressure to escape into the atmosphere. If the
pressure switch does not shut off the compressor at it's "cut-out" pressure
setting, the safety valve will protect against high pressure by releasing
tank pressure at it's factory set pressure (slightly higher than the pressure
switch "cut-out" setting). To operate manually, pull the ring on the valve to
relieve air pressure in the tank.
Pressure Release Valve (see C)
The pressure release valve (located on the bottom of the pressure
switch), is designed to release compressed air from the compressor head
and outlet tube when the compressor reaches "cut-out" or is shut off. The
pressure 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 after brief
release after reaching "cut-out" pressure.

COMPRESSOR CONTROLS

Tank Pressure Gauge (see D)
This gauge measures the pressure level of the air stored in the tank.
It is not adjustable by the operator, and does not indicate line pressure.
Air Pressure Regulator (see E)
This air pressure regulator enables you to adjust line pressure to the
tool you are using.
WARNING:
pressure of the tool.
To adjust pressure setting, turn the knob clockwise to increase
pressure, and counterclockwise to decrease pressure.
Regulated Pressure Gauge (see F)
This gauge measures the
regulated line pressure.
Air line outlet (see G)
Connect 1/4" NPT air hose
to this outlet.

The flywheel 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.
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.
The compressor must be level to ensure proper lubrication of
the pump and good drainage of the moisture in the tank.
Never exceed the maximum working
