DESCRIPTION
A
Electric motor &
air compressor
pump
The motor is used to power the pump. The electric motor has a
thermal overload protector. If the motor overheats for any reason,
the thermal overload will cut off power, thus preventing the motor
from being damaged. Wait until the motor is cool. Motor resets
automatically.
Air compressor pump: to compress air, the piston moves up and down
in the cylinder. On the down stroke, air is drawn in through the air
intake valve while the exhaust valve remains closed. On the upstroke,
air is compressed, the intake valve closes and compressed air is
forced out through the exhaust valve, into the discharge line, through
the check valve and into the air tank.
B
Air tank
The tank is used to store the compressed air.
C
Manual ON/OFF
switch
This switch is used to start or stop the air compressor. Moving the
switch to the (ON) position will provide automatic power to the
pressure switch which will allow the motor to start when the air tank
pressure is below the factory set cut-in pressure. When in the (ON)
position, the pressure switch stops the motor when the air tank
pressure reaches the factory set cut-out pressure. Moving the switch
to the (OFF) position will remove power from the motor and stop the
air compressor.
D
Pressure regulator
knob
Use the pressure regulator knob to adjust the amount of air being
delivered through the hose.
The air pressure coming from the air tank is controlled by the regulator
knob. Turn the pressure regulator knob clockwise to increase
discharge pressure and counterclockwise to decrease discharge
pressure. Follow tool operating instructions for recommended pressure
range.
E
Tank pressure
gauge
The tank pressure gauge indicates the pressure of the air in the tank.
F
Regulator
pressure gauge
The current line pressure is displayed on the regulator pressure gauge.
This pressure can be adjusted by rotating the pressure regulator knob.
G
Quick coupler
The outlet is used to connect the 1/4 in. NPT air hose.
H
Drain valve
The drain valve is used to remove moisture from the air tank after the
air compressor is shut off.
I
Safety valve
This valve is designed to prevent system failures by relieving pressure
from the system when the compressed air reaches a predetermined
level. The valve is preset by the manufacturer and must not be
modified in any way. To verify the valve is working properly, pull on
the ring. Air pressure should escape. When the ring is released, it will
reset.
