SPEED and PRESSURE REGULATION ADJUSTMENT
-
Normally, regulation requires no adjusting, but if correct adjustment is lost, proceed as follows: Refer to
the diagram above. Refer to the diagram above. 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 normal operating discharge pressure
(refer to
GENERAL INFORMATION
) and full speed position. If the tachometer moves away from the full
speed position before normal operating discharge pressure is attained, then turn the adjusting screw ‘
A
’
clockwise to increase the pressure. Optimum adjustment is achieved when the throttle just moves from
its full speed position and the pressure increases slightly. Close the service valve. The engine will slow
to idle speed.
CAUTION
!
Never allow the idle pressure to exceed maximum allowable pressure.
