SPEED AND PRESSURE REGULATION ADJUSTMENT
Normally, regulation requires no adjusting, but if correct adjustment is
lost, proceed as follows:
Refer to the diagram above.
Start the machine (Refer to STARTING INSTRUCTIONS in the
OPERATING INSTRUCTIONS section of this manual).
Inspect the throttle arm on the engine governor to see that it is
extended in the full speed position when the engine is running at full
load speed and the service valve is fully open. (Refer to the GENERAL
INFORMATION section of this manual).
Adjust the service valve on the outside of the machine to maintain
normal operating discharge pressure without the throttle arm moving
from the full speed position before normal operating discharge
pressure is attained. Turn the adjusting screw clockwise to increase
the pressure. Optimum adjustment is achieved when the throttle arm
just moves from its full speed position and the pressure gauge reads
normal operating discharge pressure.
Close the service valve. The engine will slow to idle speed.
A. Throttle Arm
B. Adjusting Screw
C. Engine Governor
D. Separator Tank
E. Inlet Unloader
CAUTION: Never allow the idle pressure to exceed maximum
allowable pressure on the pressure gauge, otherwise the safety valve
will operate.
