4.6 PERIODICAL CHANGE OF THE COMPONENTS CONNECTED
WITH SAFETY
To ensure safety at any moment while driving and using the machine, the operator must carry out all the periodic
maintenance operations prescribed. Furthermore, the operator must periodically change the components indica-
ted in the table in the following page, which are especially related to safety and fire-prevention rules. These com-
ponents are subject to wear and since it is particularly difficult to evaluate their conditions through simple periodic
maintenance, after a certain period it is advisable to change them independently of their state, in order to keep
them efficient over time. Repair or replace these components immediately in case of failures or anomalies, even if
the time interval prescribed for their change has not elapsed yet.
If the pipe clamps show signs of deterioration, like deformations or cracks, provide for changing them together with
the pipes.
In addition to the periodical change of the components listed in the following page, carry out the inspections descri-
bed here below on the hydraulic pipes. In case of anomalies, carry out the necessary adjustments and changes, or
adopt any other measure required.
