6.7 APPLICATION OF THE OFFSET DEVICE
WARNING
q
When it is necessary to move the machine or travel on roads, the offset device must be positioned
centrally with respect to the boom axis.
q
To carry out digging operations on vertical walls, the fulcrum pin (1) of the revolving support (2) must be
perfectly vertical; be very careful to the position of this component when digging near walls and posts,
wells and underground lines.
q
When digging near walls, take care not to weaken foundations and cause collapses.
q
When working beyond the outline of the machine, make sure that the ground on which the stabilizers
and wheels rest is solid and the area is sufficiently far from ridges, banks, coasts: remember that in
these conditions the specific pressure on the ground always increases.
Reduce the loads and work at low speed, in order to ensure the stability of the machine.
6.7.1 DESCRIPTION AND CONTROL
The offset device is an integral part of the boom (3) and makes it
possible to carry out digging operations beyond the machine
outline.
If the offset device is in neutral position, the boom can be used as
a standard boom; if it is necessary to dig beyond the machine
outline, the backhoe must be translated and the offset device
must be operated to reproduce the parallelism between the arm
(4) and the axis of the machine.
