Level Sensors
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 and 3° to the front
or rear.
How to Install and Calibrate the
1.5° 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.
1 Move the machine to an area that has a firm,
level surface and is free of obstructions.
2 Remove the platform controls from the platform.
3 Turn the key switch to platform control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
4 Raise the platform 7 to 8 feet / 2.1 to 2.4 m.
5 Lift the safety arm, move it to the center of the
scissor arm and rotate down to a vertical
position.
6 Lower the platform onto the safety arm.
Crushing hazard. Keep hands
clear of the safety arm when
lowering the platform.
If you are not installing a new level sensor,
proceed to step 15.
7 Turn the key switch to the off position and push
in the red Emergency Stop button to the off
position at the ground controls.
8 Tag and disconnect the level sensor wire
harness from the chassis wire harness.
Note: The wire harness connection is located next
to the level sensor, on top of the chassis at the
steer end of the machine.
9 Remove the level sensor retaining fasteners.
Remove the level sensor from the machine.
10 Tag and disconnect the level sensor wires from
the level sensor connector plug.
11 Securely install the wires of the new level
sensor into the level sensor connector plug.
12 Place the new level sensor onto the level
sensor mount bracket with the "X" on the level
sensor base closest to the long side of the level
sensor mount, and the "Y" on the level sensor
base closest to the short side of the level
sensor mount.
Tip-over hazard. The level sensor
must be installed with the "X" on
the level sensor base closest to
the long side of the tilt level sensor
box, and the "Y" on the level
sensor base closest to the short
side of the tilt level sensor box.
Failure to install the level sensor
as instructed, could result in the
machine tipping over, causing
death or serious injury.
