Drive Control Lever Operation
Depending on the orientation of the boom and chassis,
the Drive and Steer functions may move the machine
in directions opposite of the motion of the control lever.
The color- and shape-coded arrows on the control lever
decal correspond to similar arrow decals on the machine
chassis (see illustrations). Be sure to check the arrows on
the chassis before activating and using the Drive or Steer
functions.
Drive Function speed is proportional and is controlled by
the positional of the control lever. The further it is moved
from the neutral (center) position, the faster the speed will
be.
When the boom is elevated out of the stowed position,
the maximum drive speed is reduced to 0.5 mph (0.8
km/h). Drive function speed is still fully proportional to the
position of the drive control handle.
The control lever returns to the neutral (center) position
when released. Steering Function is not proportional.

Note: The Steering Function does not automatically return the steering wheels to the centered
position. Always check the position of the steering wheels before and during machine
operation.
Test Operation
1. Drive: Squeeze the enable trigger, then move the control lever in the desired direction of
movement. The further it is moved from the neutral (center) position, the faster the speed will be.
2. Stop: Return the control lever to the neutral (center) position. Releasing the control lever will
also stop the machine. Releasing the trigger will result in a rapid stop.
• Extend the boom approximately 3 feet (1 m), then drive the machine. Speed should be
reduced signicantly from the fully-retracted, fully-lowered speed. Retract the boom.
• Elevate the boom approximately 10°, then drive the machine. Speed should be reduced
signicantly from the fully-retracted, fully-lowered speed. Lower the boom.
3. Steering: Squeeze the enable trigger, then press the thumb switch on top of the control lever to
steer in the desired direction.
Note: The Steering Function does not automatically return the steering wheels to the centered
position. Stay alert to the position of the steering wheels before and during machine operation.
