FUNCTIONING
2. When travelling uphill in reverse, avoid steering at the
beginning of the slope.
If this is absolutely necessary, carry out the manoeuvre
gradually.
3. Avoid traveling along the edge of slopes or on rough
ground with one track raised (machine inclination
exceeding 10°) and with the other track on flat ground. To
avoid damaging the rubber tracks, always proceed with
both tracks resting on the same horizontal plane.
4. If the machine is operated in the conditions described in
points from 1 to 3 above, do not change direction if the
tracks do not adhere perfectly to the ground, see figure.
