ADJUSTMENT
1. Loosen the two mounting bolts that secure the slotted interlock switch
plate.
2. Slide the slotted interlock switch plate toward the gearbox disconnect
lever until the arm of the gearbox disconnect lever contacts the slotted
interlock switch plate.
NOTE: When the manual disconnect handle is in run mode/normal
operation, the gearbox disconnect lever should fully depress the interlock
switch.
3. Ensure that there is a small gap of clearance between the gearbox
disconnect disk and the arm of the gearbox disconnect lever. If there
is no gap when the interlock switch is depressed, adjust the position
of the slotted interlock switch plate away from the gearbox disconnect
lever.
4. While holding the slotted interlock switch plate in contact with the arm
of the gearbox disconnect lever, tighten the two mounting bolts.
