Connect the battery; refer to the electrical system maintenance section of your Operator’s Manual.

Adjusting the Cooling Fan Position

  1. Seat the operator of the machine in the operator’s seat.

  2. Rotate the fan switch to medium fan speed.

  3. Determine if the operator wants the airstream of the cooling fan moved forward or rearward:

    • If the airstream position is correct, shut off the cooling fan.

    • If the operator wants the airstream of the cooling fan moved, perform the following steps:

      1. Shut off the cooling fan.

      2. Remove the 4 carriage bolts (1/4 x 5/8 inch) and 4 flange locknuts (1/4 inch) that secure the switch panel to the left and right side-frame channels (Figure 12).
