The basic rule is: Do not use the vehicle until the snow is
deep enough to prevent damage to the underlying vegeta-
tion.
The objective in preparing a ski-slope is to achieve visually
excellent slope quality:
Build up supplies of snow in good time at critical points, so that
reserves will be available to make up for the snow removed
from the slope.
Holes and snow heaped up by movement and by manoeuvring
must be smoothed out with as little delay as possible.
If speed is excessive, the tracks will throw snow out sideways
and over the auxiliary equipment onto the prepared surface.
Regularly remove snow from the load platform. Otherwise, the
increase in weight will result in higher fuel consumption.
Always operate the vehicle within the economical rpm range
(marked in green on the revolution counter).
The driving speed is controlled electronically depending on the
engine speed.
Driving: uphill
Always study upgrades and look for the easiest route; do not
start at the steepest point. Frequently, it is better to detour to
the highest point of a slope via an alternative route and then
work from the top down to prepare the first part of the run.
Whenever possible, negotiate slopes by following the line of
fall and by keeping steering movements to a minimum.
Do not overrev the engine: use only as much power as is neces-
sary; note the level of traction. Over revving will cause the
tracks to slip, with the result that the vehicle will dig into the
snow. If the tracks start to dig in stop immediately and try a
different line.
Digging in ruins the ski-slope and destroys the surface
beneath the snow.
Turning
In order to avoid damaging the surface of the ski-slope, you
must turn at or beyond the edge of the prepared slope. You
should, of course, use areas that are free of vegetation (forestry
plantations and the like) for this purpose.
Always keep the front-mounted and rear-mounted auxiliary
equipment raised when turning.
