PERIODICAL CHANGE OF THE COMPONENTS THAT ARE CONNECTED WITH SAFETY
4.6 PERIODICAL CHANGE OF THE COMPONENTS THAT ARE
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 indicat-
ed in the table in the following page, which are especially related to safety and accident-prevention rules. These
components are subject to wear and since it is particularly difficult to evaluate their conditions through simple pe-
riodic 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, the inspections described
here below are to be carried out on the hydraulic pipes. In case of anomalies, carry out the necessary adjust-
ments and changes, or adopt any other measure required.
