MACHINE OPERATIONS AND CONTROLS
When traveling in reverse up a slope, do not turn when
moving from flat ground onto the slope.
If it is necessary to turn on slopes, be sure to turn gradu-
ally.
Avoid traveling along the edge of slopes or on rough
ground with the track on one side raised (with the machine
tilting at an angle of more than approx. 10°) and with the
track on the other side on flat ground. To avoid damage to
the rubber shoes, travel with the tracks on both sides on
flat ground.
Mechanism of rubber shoe coming off track
1) When traveling over an obstacle, a gap is formed
between the track roller and the rubber shoe. In this
condition, the rubber shoe may come off.
2) Furthermore, if the machine travels in reverse, a gap
is formed between the track roller, idler, and rubber
shoe.
