10 Maintenance and repair
10.1 Maintenance log
We recommend that a maintenance log is kept to record service/maintenance/repair,
addition and alteration of the equipment. Each note, observation or comment should
be dated.
10.2 Preventive maintenance
Common
The maintenance of hydraulic systems is designed to prevent failure of the system
and to keep the system running efficiently to specification. The specific procedures
will depend on the nature of the equipment, the environment it is working in and
the duty cycle, bearing in mind the consequences of a breakdown. To optimise
the maintenance intervals economically a Life Cycle Cost (LCC) analysis is
recommended.
