Traveling Forward and Reverse

At Platform Controls, pull out Emergency Stop switch, start
engine, and activate footswitch.
2.
Position Drive controller to Forward or Reverse as desired.
This machine is equipped with a Drive Orientation Indicator. The
yellow light on the platform control console indicates that the
boom is swung beyond the rear drive tires and the machine may
Drive/Steer in the opposite direction from the movement of the
controls. If the indicator is illuminated, operate the Drive function
in the following manner:
1. Match the black and white direction arrows on both plat -
form control panel and the chassis to determine the direc -
tion the machine will travel.
2.
Push and release the Drive Orientation Override switch.
Within 3 seconds, slowly move the Drive control toward the
arrow matching the intended direction of machine travel.
The indicator light will flash during the 3 second interval
until the drive function is selected.
Traveling on a Grade
When traveling a grade, maximum braking and traction are obtained
with the boom stowed, in position over the rear axle, and in line with
the direction of travel. Drive the machine forward when climbing a
grade, and in reverse when descending a grade. Do not exceed the
machine's maximum rated gradeability.
IF THE BOOM IS OVER THE FRONT (STEER) AXLE, DIRECTION OF STEER AND DRIVE
MOVEMENT WILL BE OPPOSITE FROM THE MOVEMENT OF THE CONTROLS.
