IMPORTANT: Prior to setting fan speed, allow tractor hydraulic oil to warm up to operating temperature. Cold oil will cause slower fan speeds.

Motor case drain hose must be connected before running fan, or motor shaft seal will fail within 30 seconds.

1. Put display console (A) in "RUN" mode, and locate Fan (rpm) display and set key.

2. Depress Fan (rpm) "SET" key.

4. Fan speed indicator lights (A and B) can be observed while setting fan speed.

Lower light (A) is on when fan first starts turning and actual speed is below target speed by more than 5 percent.

When both lights shine steady, fan is turning at target speed (+/- 5%) entered in the display console.

Top light (B) comes on and bottom light (A) goes off when target speed has been exceeded by more than 5 percent.

Most accurate setting will be realized by observing the display console's fan speed readout.
