DANGER
•
Always engage the boom safety lock when the backhoe is
not used and when travelling on roads.
This is a two-position switch and is used to connect the boom to
the safety lock (A).
In the rest position (led off) the backhoe is free and can move
without any interference with the lock.
The switch is in this position even when the boom is connected
to the safety lock.
To engage the safety lock, proceed as follows:
Select the uncoupling position by pressing the switch (8) (led
on), fold the arm and the bucket, raise the boom completely and
engage the lock by pressing the switch again (led off).
Before moving the machine, make sure that the lock is properly
positioned in its seat.
IMPORTANT
☞
•
If the machine is equipped with backhoe servo controls,
the switch (8) is positioned on the upper part of the side
dashboard, as shown in Fig. B.
The switch (8) can be disabled by means of the switch
(27).
