4.7 PERIODICAL CHANGE OF SAFETY-RELATED COMPONENTS
To ensure safety at any moment while driving and using the machine, the operator must carry out all the routine
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 fire-prevention rules. These compo-
nents are subject to wear and since it is particularly difficult to evaluate their conditions through simple routine
maintenance, after a certain time interval 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 be-
low are to be carried out on the hydraulic pipes. If any anomaly is observed,
For the quantities and codes of the safety-related components to be changed, see the spare parts catalogue.
When changing pipes, always change O rings, gaskets and analogous components.
Type of check Items to be checked
Before starting the engine Leakages from joints, hydraulic pipes or fuel pipes.
Periodically (monthly)
Leakages from joints, hydraulic pipes or fuel pipes. Damaged hydraulic or fuel
pipes (cracks, wear and tear).
Periodically (yearly)
Leakages from joints, hydraulic pipes or fuel pipes. Deteriorated, twisted,
damaged hydraulic or fuel pipes (cracks, wear and tear) or pipes in contact
with other parts of the machine.
