3.3.5 STEERING THE MACHINE
3.3.5.1 STEERING (CHANGING DIRECTION)
WARNING
q
Before operating the travel control levers, check the position of the sprocket. If the sprocket is at the
front, the operation of the travel levers is inverted.
q
Avoid abrupt changes of direction as much as possible. Carry out counter rotations with the machine at
rest.
q
Due to the strong friction generated by changes of direction, do not use the travel speed increase con-
trol.
NOTE
q
When the machine travels at high speed and the load increases, the low speed is automatically selected, and
the machine slows down. When the load is reduced, the travel system automatically changes over to high
speed.
Use the travel levers to change direction.
Avoid abrupt changes of direction as much as possible. In particu-
lar, when carrying out a counter-rotation, stop the machine before
steering.
Operate the two travel levers (1) as follows.
CHANGING DIRECTION WITH THE MACHINE AT REST
When steering to the left:
Push the right travel lever forward to steer to the left if the ma-
chine must travel forward; pull the lever backward to steer to the
left if the machine must travel in reverse.
(A): Left forward steering
(B): Left reverse steering
NOTE
q
To steer to the right, operate the left travel lever in the same
way.
