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. Adjusting screw
Start the machine (Refer to STARTING INSTRUCTIONS in the OPERATING
INSTRUCTIONS section of this manual).
Adjust the service valve on the outside of the machine to maintain rated pressure at full speed.
If full speed is not maintained at rated pressure, then turn the adjusting screw clockwise to
increase the pressure. Optimum adjustment is achieved when full speed is achieved at rated
pressure.
Close the service valve. The engine will slow to idle speed.
