BACKHOE TELESCOPIC ARM
252
6.5.2 SAFETY DEVICES
The telescopic arm is equipped with a safety element (5) that
locks the sliding arm (2) when it is completely retracted and
prevents any accidental extension of the same.
The safety element (6), held in its seat by the retainer (7), must be
inserted and prevent the extension of the arm as shown in Fig. A
in the following situations:
1 - when it is necessary to travel on roads or in any case when
the machine must cover considerable distances;
2 - when the backhoe is not used.
In operating conditions, the safety element (5) must be positioned
as shown in Fig. B.
6.5.3 USING THE TELESCOPIC ARM
WARNING
q
Before releasing and extending the arm, make sure that the stabilizers rest on firm ground.
q
If possible, work with the backhoe centered on the guides and unload the material as near the machine
as possible.
q
If it is necessary to work with misaligned backhoe or with the backhoe completely shifted on the guides,
operate slowly when swinging the arm to unload the material on the misaligned side, since in these
conditions the machine may lose stability.
q
Do not use the arm retracting cylinder to increase the bucket tearing force when digging.
For other possible applications, see "3.13 USING THE MACHINE AS AN EXCAVATOR".
