This machine is equipped with a Drive Orientation Indicator. The yellow light on the
platform control console indicates the boom is swung beyond the rear drive tires and
the machine may Drive/Steer in the opposite direction from the movement of the

TRAVELING (GRADE/SIDE SLOPE)

Note: Refer to the Operating Specifications table for gradeability and side slope
ratings.
All ratings for gradeability and side slope are based upon the machine's boom being in
the stowed position, fully lowered, and retracted.
Traveling is limited by two factors:
1. Gradeability, which is the percent of grade of the incline the machine can climb.
2. Side slope, which is the angle of the slope the machine can be driven across.
4.6.1 Traveling on a Grade
When traveling a grade, maximum braking and traction are obtained with the boom
stowed, in position over the rear (drive) 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.
