AIR COMPRESSOR FEATURES
OUTLET PRESSURE GAUGE: The outlet pressure gauge indicates
the air pressure available at the outlet side of the regulator. This
pressure is controlled by the regulator and is always less or equal
to the air tank pressure.
MOTOR THERMAL OVERLOAD: The electric motor has a manual
thermal overload protector. If the motor overheats for any reason, the
thermal overload will cut off power to prevent the motor from being
damaged. Turn pressure switch lever to the "OFF" position and wait
until the motor is cool. Press the thermal overload button to reset it
and begin working again.
PRESSURE SWITCH: The switch is used to start or stop the air
compressor. Moving the switch to the "Auto" (ON) position will allow
the pressure switch to start the motor when the air tank pressure is
below the factory set "cut-in" pressure. When in the "Auto" position,
the pressure switch stops the motor when the air tank pressure
reaches the factory set "cut-out" pressure. This switch also has a
pressure release valve located on the side of the switch designed to
automatically release compressed air from the air compressor pump
head and its discharge line when the air compressor reaches "cut-out"
pressure or is shut off. This allows the motor to restart freely. Moving
the switch to the "OFF' position will open the pressure switch contacts
and stop the air compressor.
AIR INTAKE FILTER: This filter is designed to clean air coming into
the pump. To ensure the pump continually receives a clean, cool, dry
air supply this filter must always be clean and ventilation opening free
from obstructions. Replace filter element when necessary.
TANK PRESSURE GAUGE: The tank pressure gauge indicates the
air pressure in the air tank.
PRESSURE REGULATOR: The air pressure coming from the air
tank is controlled by the regulator knob. Turn the pressure regulation
knob clockwise to increase discharge pressure, and counterclockwise
to decrease discharge pressure.
