Level Sensor -
Models without Outriggers
(before serial number 40077)
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, 3° to the front or 5°
to the rear.
How to Install and Calibrate the
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 specified in this
procedure.
1 Perform this procedure with the machine on a
firm, level surface that is free of obstructions.
2 Remove the platform controls from the platform.
3 Block the wheels at the non-steer end of the
machine.
4 Center a lifting jack under the drive chassis at
the steer end of the machine.
5 Raise the machine approximately
4 inches / 10 cm.
6 Place a 1.97 x 10 x 10 inch / 5 x 25 x 25 cm
thick steel block under both wheels at the steer
end of the machine.
Part No. 82259
7 Lower the machine onto the blocks.
8 Turn the key switch to platform control and pull

and the bubble in the top of the level sensor is
centered in the circles.
Result - ANSI and CSA models before serial
number 40005: The tilt alarm will sound at 180
beeps per minute. The level sensor must be
calibrated.
Result - ANSI and CSA models after serial
number 40004: The drive function and the lift
function will not operate and the tilt alarm will
sound at 180 beeps per minute. The level
sensor must be calibrated.
Result - CE and Australian models: The drive
function and the lift function will not operate and
the tilt alarm will sound at 180 beeps per
minute. The level sensor must be calibrated.
If you are not installing a new level sensor,
