LIFT-STOWED AND GRABBERS OPEN PROXIMITY SWITCHES
Adjust the proximity switches to deactivate if grabber or arms are extended outside the width of the vehicle. You will need a
15/16" wrench. The grabbers open proximity switch should be adjusted so that it is activated when the grabbers are fully
open. To make adjustments to the lift-stowed (lift-in) proximity switch, you will need a 7/16" wrench. The lift-stowed proximity
switch should be adjusted so that it is activated when the lift arm is fully stowed or retracted. See the figure below.
