PRECAUTIONS TO BE TAKEN DURING WORK
44
2.4.4 CHECKS FOR TRAVELLING IN
REVERSE
q
When operating in areas that may be hazardous or where
visibility is poor, designate a person to direct the movements
of the machine and traffic on the work site.
q
Before moving the machine, sound the horn to warn the per-
sons standing or working in the area.
q
There are blind spots behind the machine, which cannot be
seen through the rear-view mirrors and where someone may
be standing.
Therefore, it is necessary to make sure that there is no one
behind the machine before travelling in reverse.
On request the machine can be equipped with an acoustic
alarm (1) for travelling in reverse; before starting to travel in
reverse, make sure that the acoustic alarm is functioning
perfectly.
See "3.3.6 pos. 1 - REVERSING GEAR LEVER".
2.4.5 MOVING THE MACHINE
q
When moving the machine, position the front bucket at about
30–40 cm from the ground; this position makes it possible to
evaluate the space required for the movements more pre-
cisely and at the same time ensures the stability of the ma-
chine.
q
If the front bucket control lever is to be used during travel,
avoid moving it abruptly; sudden manoeuvres change the at-
titude of the machine and make driving difficult.
q
When travelling on rough ground, keep the speed low and
avoid sudden movements of the bucket arm.
q
If the machine has to overrun an obstacle, keep the front
equipment as close to the ground as possible and travel at
low speed, in order not to overload the axles and tyres.
