MOTOR/PRESSURE SWITCH:
This switch is used to start or stop
the air compressor. Moving the
switch to the "Auto" (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 Start/
Stop Option, the pressure switch
stops the motor when the air tank
pressure reaches the factor set "cut-
out" pressure. For safety purposes,
this switch also has a pressure
release valve located on the side of
the switch designed to automati-
cally release compressed air from
the air compressor pump head and
its discharge line when the air com-
pressor reaches "cut-out" pressure
or is shut off. This allows the motor
to restart freely. Moving the switch
to the "Off" position will remove
power from the pressure switch
and stop the air compressor.
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,
thus preventing the motor from be-
ing damaged. Wait until the motor
is cool before pressing the thermal
overload button to reset and begin
working again.
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 fil-
ter when necessary.
AIR COMPRESSOR PUMP: To
compress air, the pistons move up
and down in the cylinders. On the
downstroke, air is drawn in through
the air intake valves while the
exhaust valves remain closed. On
the upstroke, air is compressed,
the intake valves close and com-
pressed air is forced out through
the exhaust valves, into the dis-
charge line, through the pilot valve
and into the air tank.
PILOT VALVE: When the adjust-
ing knob is turned completely
clockwise to the fully closed po-
sition, the air compressor oper-
ates in the Start/Stop Option.
When the adjusting knob is
turned completely counterclock-
wise to the fully open position,
the air compressor operates in
the constant run position.
SAFETY RELIEF 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 reseat.
AIR TANK DRAIN VALVE: The
drain valve is used to
remove moisture from the air
tank(s) after the air compressor
is shut off. NEVER attempt to
open the drain valve when more
than 10 PSI of air pressure is in
the air tank! To open the drain
valve, turn the knob counterclock-
wise.
AIR TANK PRESSURE GAUGE:
The air tank pressure gauge
indicates the reserve air pres-
sure in the air tank (s).
PRESSURE REGULATOR: The
air pressure coming from the air
tank is controlled by the regulator
knob. Turn the pressure regula-
tion knob clockwise to increase
discharge pressure, and coun-
terclockwise to decrease dis-
charge pressure.
OUTLET PRESSURE GAUGE:
The outlet pressure gauge indi-
cates 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.
OIL DIPSTICK: The dipstick will
register the amount of oil in the
pump. Oil level should be
checked on a daily basis to en-
sure it does not exceed the maxi-
mum notch or fall below the mini-
mum notch on the dipstick
