Speed and Pressure Regulation Adjustment
Normally, regulation requires no adjusting, but if correct adjustment is lost, proceed as follows:
Refer to the diagram above.
A. Throttle Arm
B. Adjusting Screw
C. Engine Governor
D. Separator Tank
E. Inlet Unloader
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.
CAUTION
!
Never allow the idle pressure to exceed maximum allowable pressure on
the pressure gauge, otherwise the safety valve will operate.
