32 MAINTENANCE
5.15 CONTROL ADJUSTMENTS
The engine speed governor and pressure regulator are preset at the Factory and normally require no
servicing. However, if it becomes necessary to make adjustments, use the following procedures:
5.15.1 DISCHARGE PRESSURE ADJUSTMENT
Unit must be in
RUN
mode before adjusting, and with the service valve(s)
closed.
To increase pressure, loosen locknut on pressure regulator adjustment screw
and turn screw clockwise. Lower the operating pressure by turning screw
counter-clockwise.
Reset locknut after adjustment is completed. See Figure 5-3.
Check engine speed whenever pressure settings have been changed. Only the
unloaded pressure can be selected with the pressure regulating valve. Full and
part load pressures are a function of air usage.
5.15.2 ENGINE SPEED
Engine speed is controlled by the Sullivan-Palatek Electronic Controller (SPEC).
The full load and idle speeds are programmed at the Factory and there should
be no need for adjustment. If the machine is experiencing speed problems
please contact our Service Department.
