Level Sensor - Models without
Outriggers
The Electronic Control Module (ECM) is
programmed to deactivate the lift and drive
functions and activate an alarm when a signal is
received from the level sensor.
The tilt alarm sounds when the incline of the
chassis exceeds 2° to the side and 3° to the front or
rear.
How to Install and Calibrate the
Level Sensor
Tip-over hazard. Failure to install
or calibrate the level sensor as
instructed will compromise
machine stability and cause the
machine to tip over, resulting in
death or serious injury. Do not
install or calibrate the level
sensor other than specified in
this procedure.
Note: Perform this procedure with the machine on
a firm, level surface and the platform in the stowed
position. Use a digital level to confirm.

Remove the platform controls from the
platform.
Note: If you are not installing a new level sensor,
or you have installed an outrigger level sensor,
proceed to step 7.
