Level Sensor

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 1.5° to the side, or 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

install or calibrate the level sensor
other than specified in this
procedure.
Perform this procedure with the
machine on a firm, level surface
that is free of obstructions.
