SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION
Drive speed is determined by the distance the control
handle is moved from the center off position. Do not
activate the high engine speed switch when traveling
in reverse.

Traveling on Grade

If driving at high drive up a grade and the incline exceeds 8°
incline, the drive function will cut back to mid drive speed.
The drive pump will shift back into high drive once the incline
decreases to 5°. There will be a 2 second delay before the
machine goes back to high drive.

Steering

NOTE: When static steering is performed it will bring the engine
up to high speed.
To steer the machine, the thumb operated steer control
switch on the controller handle is positioned to the right
for traveling right, or to the left for traveling left. When
released, the switch will return to the center-off position
and the wheels will remain in the previously selected posi-
tion. To return the wheels to the straightened position, the
switch must be activated in the opposite direction until
the wheels are centered.
