B - Vehicle Calibration Tab

C - Calibration Icon

Hydro calibrate procedure is used to determine the characteristics of the multifunction control handle assembly for use in hydrostatic drive train control. This calibration should be performed when any of the following components are serviced or replaced:

  • Propulsion handle
  • Forward, reverse, or park switch
  • Propulsion module
  • Armrest
  • Chassis controller
  • Hydro cable

There may also be need to perform the calibration due to normal wear of propulsion control components.

  1. Select the Calibration softkey (A).

  2. Select the “Vehicle Calibration” tab (B).

  3. Select calibration icon (C) next to “Hydro Handle Calibration”. Hydro Handle Calibration screen will appear.
