Periodical Change Of The Safety Related Components - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

4.6 PERIODICAL CHANGE OF THE 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
indicated in the table in the following page, which are especially related to safety and fire-prevention rules. These
components 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, change 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 adjustments and
changes, or adopt any other measure required.
