STEER AXLE COMPONENTS

8 Install the new steer sensor assembly to

the yoke pivot pin. Loosely install the cover
retaining fasteners.

Be sure the sensor activator pin is engaged into
the sensor.

The arrow on the steer sensor cover should point
towards the front of the machine.

9 Connect the steer sensor harness to the main

harness.

10 Set a voltmeter to read DC voltage. Probe the

back of the electrical connector at the orange
wire using the positive lead of the voltmeter.
Probe the back of the electrical connector at
the black wire using the negative lead of the
voltmeter.

11 Turn the key switch to platform control.

12 Pull out the red Emergency Stop buttons to the

on position at both the ground and platform
controls.

13 Adjust the steer sensor cover so that the volt

meter reads 2.5V DC.

14 Tighten steer sensor cover fasteners.

15 Install the cable clamp to secure the steer

sensor cable to the drive chassis.

16 Install the drive chassis cover.

17 Calibrate the steer sensor. See 9-2

How to

Calibrate the Steer Angle Sensor

1 Turn the key switch to platform control.

2 Pull out the red Emergency Stop button to the

on position at both the ground and platform
controls.

3 Using the thumb rocker switch on the drive

joystick, adjust the steer wheels so they
are pointing straight ahead, in line with the
nonsteer wheels. Release the foot switch.

4 Move and hold the drive enable toggle switch in

the right direction while holding the steer rocker
switch in the right direction.

5 When the display leaves

SYSTEM READY

mode, release the drive enable toggle switch
and the steer rocker switch on the drive steer
joystick.
