Operation
WORKING WITH THE MACHINE
Other operation possibilities, in addition to the operations described below,
can be performed using other special equipment.
EXCAVATING
CAUTION
If you want to perform excavation operations with the machine
being in bent position, you may damage the articulated steering
and the cardan shaft!
Always drive into the material which you want to remove in
straight direction.
Removing piled up soil
Removing heaps of loose soil or debris of exploded rock may cause
premature wear and tear of the tyres due to cracks and small fissures.
As a result, the service life of the tyres is reduced. Proceed as follows to
avoid unnecessary wear and tear of the tyres:
• Try to work on level ground and remove any rocks and large stones
which are sticking out.
• If you are working on heaps, drive the machine in the 1st or 2nd
gear; if you are loading debris of exploded rock, drive the machine
in the 1st gear.
Proceed as follows, if you are removing loose soil or performing dozing
operations:
1. While driving forward, lower the bucket until it reaches a height of
approx. 30 cm above the ground. Then, lower it slowly.
NOTE
If the bucket touches the ground, the front wheels may be lifted
from the ground, resulting in premature wear and tear of the rear
wheels.
2. Shift to a lower gear immediately in front of the material to be
removed. Press down the accelerator pedal and drive the bucket
into the material.
3. If the material to be removed is lying on a heap, it is required that
you align horizontally the cutting edge of the bucket while driving
into the material. When you are loading rock debris, it is necessary
to dump the bucket slightly down.
• Ensure that no rock gets under the bucket. This may lead to the
front wheels being lifted from the ground, thus resulting in
premature wear and tear of the rear wheels.
• Always hold the load in the centre of the bucket. If the load is
shifted to one side, the balance of the machine will be impaired.
