McConnel ROBOCUT RC28 Operator's Manual page 33

When the machine manoeuvres over an obstacle, a space is
created between the bearing rollers and the track - this can
cause the track to come off its seat. The same situation can
occur in reverse when a space is created between bearing
roller, idler roller, and track.
If the machines changes direction, and the track cannot move
sideways due to the presence of an obstacle, there is a risk
that the track can be damaged or come of its seat; wherever
possible avoid turning the machine if it is against an obstacle, if
unavoidable, make manoeuvres slowly and gradually until the
machine is clear of the object.
If the machine moves in reverse in these conditions there is risk of
the track coming off its seat.
If the machine is steered in these conditions the track will come off its
seat
Do not change direction whilst moving on
kerbs, rocks or surfaces with considerable
differences in height (more than 20cm); in
these instances always move perpendicular
to the obstacles.
When reversing uphill, do not steer when
transferring from the level surface to the
slope; if unavoidable the manoeuvre should
be performed gradually.
