Adjust the Access Ladder
Do not ride on ladder or stand on platform while machine is moving.
To avoid damage to the ladder during machine operation, keep the ladder in the LATCHED position.
Position adjustment for the hinge.
Adjust the hinge so that the ladder is parallel to the top surface of the fender with the ladder in the UP position.
Adjustment for the location of the latch
The latch should be adjusted so that the pins for the latch are equally engaged in the top and the bottom of the ladder.
Adjustment for the contact plates on the latch
The contact plates on the latch should be adjusted in order to prevent any vertical movement or any side to side movement of the ladder when the latch pins are engaged in the ladder.
Adjustment for the location of the proximity switch
With the ladder in the Up position, adjust the proximity switch so that the switch and the magnet are aligned.
There must be a gap between the magnet and the switch in order to prevent contact when the ladder moves. The gap between the magnet and the switch must be close enough to function correctly.
