FUNCTIONING
Rear view mirrors
q Always check the cleaning and correct orientation of the rear-view mirrors before starting to work;
they must allow to control the rear area control without moving the log in relation to the normal
working position.
If working with no control at the back of the machine, incautious people who may have entered into
the working zone may be run down, or fixed obstacles or motor vehicles may be crashed during
operation.
q If rear-view mirrors shall be moved or broken during work, stop the engine immediately and fix or
replace them.
Adjust the inclination of the rear-view mirrors, so that the area behind the cab is well visible.

Mirror (A)
Loosen bolt (1) of the mirror and adjust the position so that the
best possible view of the area in front of the machine can be
obtained.
In this way there is a "blind spot" from the operator's position.
q Upon installing the mirror, adjust it so that you are able to
see any person at the rear left or right end of the machine
(at both sides of the conveyor) or any objects that are 1 m
(3.9 in) high and within a 30 cm (1.2 in) diameter.
q Adjust the angle so that the side panel of the machine is
reflected on the mirror as illustrated in the figure on the
right.
