NOTE: Although the pump is shown removed for clarity, most repairs and adjustments can be made without removing
the hydrostat.
The machine must be operating to check system pressures. Make certain that everyone is clear of the ma-
chine and all gauges are secured. Z023
Raise the combine drive wheels off the ground to prevent the combine from travelling uncontrolled when
making adjustments. Be sure to use suitable blocking or jack stands to support the weight of the combine.

If equipped with powered rear axle make certain the switch is off. Z015
1. MULTI-FUNCTION VALVE ADJUSTMENT
In order to set the pressure on the limiter or relief
valves, the motor output shaft must be locked so it
does not rotate. This may be accomplished by lock-
ing the brakes.
NOTE: Take necessary precautions that the motor shaft
remains locked during the adjusting procedure.
2. Install two 690 bar (10,000 psi) pressure gauges in
the high pressure gauge ports (1) and (2).
Start the combine and operate at normal speeds.
3. Loosen locking nut (smallest hex on multi-function
valve) (1).
