Confirm the front-to-back level sensor setting:
37 Center a lifting jack under the drive chassis at
the steer end of the machine.
38 Raise the machine approximately
6 inches / 15 cm.
39 Place a 4.08 x 10 x 10 inch / 10.36 x 25 x 25
cm thick steel block under both wheels at the
steer end of the machine.
40 Lower the machine onto the blocks.
41 Raise the platform at least 12 feet / 3.6 m.
Result: The platform stops raising and the tilt
alarm will sound at 180 beeps per minute.
Result: The platform does not stop raising and
the tilt alarm does not sound. The level sensor
must be replaced. Repeat this procedure
beginning with step 2.
Note: For reference only, the output of the level
sensor should be approximately 1.5V DC. To
confirm, connect the positive lead of a multimeter
to the blue wire at the level sensor, and the
negative lead to the black wire.
42 Lower the platform to the stowed position.
43 Raise the machine approximately
6 inches / 15 cm.
