17 Adjust the "X" axis (front-to-back) to 2.43V DC.
Tap the top of the level sensor lightly with
fingers after each turn of an adjusting nut.
Tip-over hazard. Do not adjust the
potentiometers on the bottom of
the level sensor or calibrate the
level sensor other than specified in
this procedure. Failure to calibrate
the tilt level sensor as instructed
will cause the machine to tip over
resulting in death or serious injury.
Note: Be sure there are threads showing through
the top of each adjusting nut.
18 Disconnect the positive and negative leads.
19 Apply Sentry Seal to the adjusting nuts.
20 Push in the red Emergency Stop button to the

23 Center a lifting jack under the drive chassis at
the ground control side of the machine.
24 Raise the machine approximately
6 inches / 15 cm.
25 Models with RT tires: Place a
2.15 x 10 x 10 inch / 5.46 x 25 x 25 cm thick
steel block under both wheels at the ground
controls side of the machine.
All other models: Place a
2.25 x 10 x 10 inch / 5.72 x 25 x 25 cm thick
steel block under both wheels at the ground
controls side of the machine.
26 Lower the machine onto the blocks.
27 Pull out the red Emergency Stop button to the

engine.
28 Raise the platform at least 12 feet / 3.6 m.
Result: The platform stops raising and the tilt

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 1.7V DC. To
confirm, connect the positive lead of a multimeter
to the yellow wire at the level sensor, and the
negative lead to the black wire.
