Setting Fan Speed-Tractor With Mechanical SCV'S Outside of CabIMPORTANT: 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, locate Fan (rpm) display and set key. 2. Depress Fan (rpm) SET key. NOTE: Refer to Operating the Machine-Air System section. 3. Enter target fan speed (rpm). DO NOT exceed 5000 rpm maximum fan speed.

If adjustment is made by an assistant, be sure they are well clear of machine before operating or they may be severely injured or killed. IMPORTANT: Do not exceed 5000 RPM maximum fan speed. NOTE: Using excessive fan speed (RPM) will damage seed, increase wear on system and blast seed out of the seed bed. Inadequate air velocity will result in plugged lines. 5. Observe fan speed indicator lights (A and B) while adjusting metering valve (C). 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. 6. With both lights shining steady, leave metering valve in adjusted position and use SCV tractor control lever for fan on/off control. |

CAUTION:
To prevent serious injury or death from unexpected machine movement, always shift the transmission to "PARK" and set the brakes when leaving the tractor.
