Drive Enable Limit Switch
A properly functioning drive enable limit switch is
essential for safe machine operation and
workplace safety. The drive enable limit switch
stops the drive function when the boom is rotated
past a non-steer tire and alerts the operator that
the machine may drive in the opposite direction
that the drive and steer control handle is moved.
1 Start the engine from the ground controls and
rotate the boom between the steer and
non-steer tires. Turn the engine off.
2 Visually inspect the drive enable limit switch for
the following:
· Broken or missing roller or arm
· Missing fasteners
· Loose wiring
