Test the Drive Enable System

Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Proper drive enable system operation is
essential to safe machine operation. When the
boom is past the non-steering wheels, drive
movement is stopped and the
indicator light turns on. The drive
enable switch must be held to
either side to reactivate the drive
function and should alert the
operator that the machine may
move in the opposite direction that the drive and
steer controls are moved. An improperly functioning
drive enable system may allow the machine to be
moved into an unsafe position.
Note: Perform this procedure with the boom in the
stowed position.
1 Start the engine from the platform controls.
2 Press down the foot switch.
3 Rotate the turntable until the boom moves past
one of the the non-steer wheels.
Result: The drive enable indicator light should
turn on and remain on while the
boom is anywhere in the range
shown.
4 Slowly move the drive control
handle off center.
Result: The drive function should not operate.

5 Rotate the turntable until the boom moves past
the other non-steer wheel.
Result: The drive enable
indicator light should come on
and remain on while the boom
is anywhere in the range shown.
6 Move and hold the drive enable toggle switch to
either side and slowly move the drive control
handle off center.
Result: The drive function should operate.
Note: When the drive enable system is in use, the
machine may drive in the opposite direction that the
drive and steer control handle is moved.
