3.6.5.3 WORKING ON SLOPES
WARNING
q
Before starting work on slopes, always check the func-
tionality of the brakes and of the parking brake.
q
Always engage the four-wheel drive.
q
Avoid engaging the high gears.
q
Do not move downhill with the gearshift in neutral, but
keep always the low gears engaged.
NON-COMPLIANCE WITH THESE RULES MAY CAUSE
YOU TO LOSE CONTROL OF THE MACHINE AND THIS
MAY OVERTURN.
q
Avoid using the declutch push button.
When working on slopes some precautions should be taken to
avoid risks for the operator and anyone in the vicinity; the
checks and operations to be carried out are the following:
1 - Always check the work area for snow, landslips, gravel,
loose ground and anything that may suddenly modify the
work conditions and the stability of the machine.
2 - When it is necessary to travel downhill, the front bucket
must always be directed downward, in transport position.
3 - When loading or travelling uphill, the front bucket must al-
ways be directed upward.
4 - When moving the machine during work, always lower the
front bucket.
5 - Carry out any lateral movement on a flat surface at the
beginning or at the end of the slope; if this is not possible,
move obliquely, keeping the machine axis as parallel to
the slope directrix as possible.
Do not move too obliquely, or, even worse, with the ma-
chine axis rotated by 90° with respect to the slope direc-
trix.
