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.
