R. Periodic Maintenance
Some parts of the machine must be checked and/or replaced on a periodic
basis to ensure a specific level of machine performance. These parts are likely
to affect the performance once they fail even in the absence of external change
or damage. Whenever possible, plan their replacement so that it will coincide
with a scheduled service visit.
Note:
All periodic maintenance shown in the below table is for reference
purposes only and are subject to change without notice. Refer to the Service
Manual for additional information.
