5-6 Section 5: Maintenance & Service
Drive Motor Rotation
Warning!: Make sure the wagon is o the stop dogs when testing the motor
direction. Until the motor direction is correct do not have the wagon come in
contact with the stop dogs or mechanical failure could occur.
1. Make sure wagon is o the stop dogs. Rotate the drive pulley manually until the string wagon
is at the front of the pinsetter. Cycle power to make sure motor/wagon is turning in the correct
direction.
2. If the motor is running backward, swap any two of the three supply wires at the motor’s
terminal block. This will reverse the direction of the motor shaft. Refer to Figure5-5.
WARNING: Never swap the ground (earth) wire with one of the supply wires.
