WHEN MAKING PIVOT TURN TO LEFT WHILE TRAVELING
When steering the machine, if the lever is operated further from
the position where it becomes heavy, the left and right tracks
will rotate in opposite directions and the machine will carry out
a counterrotation turn.
REMARK
When carrying out a counterrotation turn to the right, move the
joystick (1) to the right in the same way.
TURNING WHILE DESCENDING A SLOPE 3
This machine does not cross-steer even when it descends a steep slope where it is driven down by its own weight
or when it is pushed down by a towed machine on a slope.
REMARK
Cross steering means the phenomenon that the machine turns in the opposite direction to the actual steering
direction.
WHEN DRIVING FORWARD AND TURNING TO LEFT
If the steering, directional, and speed lever (1) is operated to
the FORWARD position and moved partially to the left (L), the
machine will start to turn gradually. After that, the lever can be
moved further towards the position where it becomes heavy to
give the desired turning radius.
(Does not become reverse steering)
REMARK
To turn gradually to the right while traveling FORWARD, if the
steering, directional, and speed lever (1) is operated to the
FORWARD position and moved slowly to the right, the
machine will start to turn gradually. After that, the lever can be
moved further towards the position where it becomes heavy to
give the desired turning radius.
Do the same when traveling in reverse.
