Loosely mount the sensor plate to the left lift
arm with 2 carriage bolts (5/16 x 1-1/4 inch) and
2 flange nuts.
Note:
Do not tighten the jam nuts at this time.
3.
Position the sensor plate as shown in
Note:
Make sure the switch does not contact

the proximity switch and tighten the carriage
bolt nuts. Ensure that it does not contact the
proximity switch.
6.
Using the jam nuts, adjust the proximity switch
up or down until the gap between the switch
plunger and the sensor plate is 3.8 to 4.3 mm
