DANGER
•
If it is necessary to carry out maintenance operations or
to stop the machine with raised loader arm, always en-
gage the mechanical safety lock and the control lever
lock.
•
When travelling on roads, always engage the mechanical
lock, lock the control lever in order to keep the front buck-
et in a stable position and use the front bucket antirota-
tion lock and the teeth protection.
•
When travelling on roads or when the backhoe is not be-
ing used, always connect the boom to the safety lock, fold
the arm and the bucket completely and lock both the
swing and the control lever. If the machine is equipped
with backhoe servo controls, always engage the control
locking safety device by pressing the relevant switch, see
“3.3.6.2 MACHINE CONTROLS (Version with servo con-
trols)”, pos. 27.
Non-compliance with these rules may cause serious dam-
age in case of accidental lowering or rotation of the equip-
ment.

The loader arm is provided with two safety locks that have two
distinct essential functions:
a) SAFETY LOCK (1): for the position of the arm when the
machine is subjected to maintenance on the engine unit
and inspection of the hydraulic system equipment and of
the auxiliary equipment housed in the engine compart-
ment and in any case to the inspections and maintenance
operations that must be carried out with raised arm (A).
b) SAFETY LOCK (2): for the position of the arm when the
machine is travelling on roads (B).
It is important to remember that in work conditions the safety
lock (1) must be positioned against the arm (C) and secured in
that position by means of the safety pin (3), while the safety lock
(2) must be put in the tool compartment positioned in the opera-
tor’s cab, under the seat support.
IMPORTANT
☞
•
The safety locks (1-2) must always adhere to the stems of
the hydraulic cylinders on whose eyes they are applied.
•
The safety locks must be positioned definitively by bring-
ing the contact surfaces against each other with a slow
and continuous movement, in such a way as not to dam-
age the cylinder head surfaces.
•
When the safety locks are in their definitive position, fas-
ten them with the safety pins (3).
