FEATURES
UNLOADER VALVE
When the maximum air tank pressure is obtained, the unloader
valve (H) will blow-off. This will cause the compressor to exhaust
the air to the atmosphere and not the tank. The valve is preset by
the manu facturer and must not be removed or modified in any way.
Manual Lock: The manual lock allows you to manually unload the
compressor with air pressure in the air tank. To operate the manual
lock:
Rotate the manual lock unloader lever to the
open position to prevent air tank pressure
buildup. Rotate manual lock unloader lever to
the closed position after starting the engine
to allow air tank pressure to build. NOTE: Air
will not build in tank when manual lock
unloader lever in the open position.
SAFETY VALVE
This valve (I) is designed to prevent system failures
by relieving pressure from the system when the
compressed air reaches a predeter mined level. The
valve is preset by the manu facturer and must not be
removed or modified in any way.
AIR INTAKE FILTER
The filter (A) is designed to clean air entering the pump.
To ensure the pump continually receives a clean, cool,
and dry air supply the filter must always be clean and
the filter intake must be free from obstructions.
AIR TANK DRAIN VALVES
The drain valve (J) is used to remove
moisture from the air tank after the air
compressor is shut off.
AIR TANK PRESSURE GAUGE
The air tank pressure gauge (D) indicates air pressure in the air tank.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (E) indicates the air
pressure available at the outlet side of the
regulator. This pressure is controlled by the
H
H
regulator and is always less or equal to the air
tank pressure.
REGULATOR
CLOSED
OPEN
The regulator knob (F) controls the air pressure coming from the air
tank.
To Adjust Regulator:
I
1. Turn knob clockwise to increase regulated pressure and
counterclockwise to decrease regulated pressure.
WARNING: Risk of Bursting. Too much air pressure causes
a hazardous risk of bursting. Check the manufacturer's
maximum pressure rating for air tools and accessories. The
regulator outlet pressure must never exceed the maximum
A pressure rating.
THROTTLE CONTROL
When maxi mum air tank pres sure is reached and the unloader
valve vents air, it activates the throttle control on the engine. This
gas saving feature holds the engine at a factory-set idling speed
until air pressure in the air tank drops to reset pressure. The
unloader valve then reactivates the throttle control and accelerates
the engine to full throttle.
