All four tread width indicators should
have identical readings after tread adjustment
is complete.
NOTE: When significant adjustment is being
made, it is recommended that you
adjust one leg at a time and perform
the adjustments in smaller
increments. Binding may occur if a
larger adjustment is made all at once,
especially if adjusting one leg at a
time.
LADDER
To Lower the Ladder
NOTE: Your machine is equipped with either
Version 1 or Version 2 of the
Hydrostatic Drive Control Handle. In
addition to difference in the
placement of controls, Version 1
allows the Parking Brake to engage/
disengage and the Ladder to extend/
retract through the Hydrostatic Drive
Control Handle (moving the handle
fully to the right). For machines
equipped with Version 2, a separate
parking brake switch is located
adjacent to the Hydrostatic Drive
Control Handle (which engages the
Parking Brake and lowers the
Ladder when activated). Refer to
specific operating instructions for
your machine.
