Level Sensor

Each machine is equipped with two types of level
sensors:
Tilt level sensor
One level sensor monitors the incline of the
turntable after the outriggers are deployed and the
machine is level. When this level sensor activates,
an alarm will sound, making the operator aware of
a potentially hazardous situation.
The tilt alarm sounds when the incline of the
chassis exceeds 2.5° in any direction. The tilt
level sensor is located on the side of the machine
opposite the ground controls.
Outrigger auto level system
When deploying the outriggers using the autolevel
function, outrigger level sensors are used to
monitor the incline of the turntable and assist in
leveling the machine.
In early production, two level sensors are
components of the outrigger auto level circuit.
Later in production, a single autolevel module was
used. The outrigger level sensor(s) are located on
the ground controls side of the machine.
How to Install and Calibrate the
Tilt Level Sensor
Tip-over hazard. Failure to install
or calibrate the level sensor as
instructed could result in the
machine tipping over causing
death or serious injury. Do not
install or calibrate the level
sensor other than specifi ed in this
procedure.

level the machine and raise the wheels off the
ground. Use the bubble levels located on the
chassis to confi rm that the machine is level.

5 Locate the tilt level sensor behind the
inspection door on the side of the machine
opposite the ground controls.
