PROCEDURE

1.Turn the engine off, open the doors on the control panel end of the machine and disconnect the nega- tive battery cable. The doors must be secured while disconnecting the battery cable.

WARNING: Secure the doors in the open position using the door restraint system. If the machine does not have a door restraint system, remove the doors or securely restrain them to prevent them from falling closed.

2.Remove the roof and doors.

3.Inspect the output control unit:

4.Carefully examine the unit. Check for arc damage, missing or broken springs, burned and/or badly worn contacts. Also look for missing or damaged insulators, poor lead connections, and damaged lead insulation. If there is serious damage to the inside diameter of the winding, the Output Control Unit should be replaced. See Figures F19 and F.20.

5. Disassemble the continuous control unit:

If service is necessary, remove the fuel tank and dis- connect the heavy cable attached to the output stud, at the center back on the output control.

6.Remove the Output control handle.

7.Remove the two screws holding the Brush holder stud assembly. Use caution, the shaft is under spring tension. The stud assembly and the rotating brush holder/contact assembly can now be removed through the back of the unit. See Figures F19 and F.20.
