Maintenance Instructions ADJUSTMENTS
ADJUSTMENTS
Safety Switches
There are three (3) safety interlock switches on the
tractor. Use the panel nuts on the switch body to po-
sition the switch for proper activation of the switch.
The adjustment procedure for each switch is:
Seat Switch
Adjust switch position in body panel to achieve a
1/32 to 1/16 in. (.79 mm to 1.59 mm) air gap between
the switch plunger and seat frame with no weight on
the seat. Test for proper operation.
FSC Neutral-Park Switch
1. Place the FSC in NEUTRAL-PARK position.
2. Adjust switch to the point where the starter en-
gages when the ignition switch is turned to the
start position.
3. Adjust switch position forward an additional 1/2
to 1 turn of the panel nuts.
NOTE: If the switch cannot be adjusted forward
enough to achieve proper function, it may be
necessary to bend the switch mounting bracket
slightly.
PTO Switch
With the PTO engaged, adjust switch to achieve a
1/64 to 1/32 in. (.40 mm to .79 mm) gap (plunger ex-
tension) between the switch body and the actuator
plate.
Tail Wheel Bearing Preload
Preload the tail wheel bearings by tightening the ax-
le nut until the wheel begins to tighten as it turns (not
spin freely), then loosen the nut 1/2 to 1 turn. The
wheel should spin freely without excessive end play.
Lock the axle nut with the set screw in the nut.
DANGER
If the engine must be running to perform
a maintenance adjustment, keep hands,
feet, and clothing from moving parts. DO
NOT wear jewelry or loose clothing.
