3.1 SAFETY LOCKS
If it is necessary to stop the machine with raised loader arm, always engage the mechanical safety lock
q
on the arm and lock the equipment and travel control by lifting the safety bars (see "3.3.5 pos. 1 - SA-
FETY BARS").
When travelling on roads with a machine homologated for this purpose, lower the loader arm complete-
q
ly, engage the bucket antirotation lock, apply the teeth guard and lock the equipment control by shifting
the safety device lever to the lock position.
When travelling on roads with a machine homologated for this purpose and equipped with excavator,
q
fold the bucket completely, apply the lock between boom and arm, the antirotation lock between boom
and sliding plate and the centre lock of the sliding plate.
Raise the stabilizer supports completely, couple the relevant safety chains and finally lock the equip-
ment control by shifting the safety device lever to the lock position. If the machine is also equipped with
rear stabilizers, raise the supports and lock them with the relevant safety chains.
When travelling on roads with a machine homologated for this purpose and equipped with asphalt cut-
q
ter, apply the lock on the lifting jack in order to keep the equipment at a given distance from the ground,
lower the loader arm completely, install the antirotation lock of the front equipment and finally lock the
equipment control by shifting the safety device lever to the lock position.
Non-compliance with these rules may lead to serious accidents.

3.1.1 LOADER LOCKS

The loader arm is provided with a safety lock (1) to be used
q
to keep the arm raised when the machine is serviced or rou-
tine operations are carried out.
The engagement of the safety lock must be carried out by
q
two persons, one seated in driving position to check the
movements of the machine and the other standing on the
ground to engage the lock correctly.
It is important to remember that in operating conditions the
q
safety lock (1) must be positioned against the arm and kept
in this position by means of the safety pin (2).
After engaging the lock (1), fasten it with the safety pin
q
(2) held by the split pin (3).
Do not carry out any operation under the raised loader
q
arm if the safety lock (1) has not been engaged.
IMPORTANT
Always open the engine hood (see "3.5.1 ENGINE
q
HOOD") before lifting the loader arm.
The safety lock must always adhere to the hydraulic cyl-
q
inder rod.
The safety lock must be brought to its definitive position
q
by moving the contact surfaces slowly and continuous-
ly, in such a way as not to damage the cylinder head sur-
face.
