Segment Six — Maintenance<br />
and Fault-Finding<br />
Welcome to the final segment in this Module in which we will<br />
look at the maintenance which a hydraulic system requires and<br />
how you can carry out some simple fault-finding.<br />
AIMS OF THE SEGMENT<br />
The main aim of this Segment is to achieve Objectives No. 5 and<br />
6 on pagexiii.<br />
For this you should be able to:<br />
• State the key maintenance problems which can arise in a<br />
hydraulic system.<br />
• State the items of maintenance which should be carried out<br />
regularly.<br />
• Describe simple maintenance procedures.<br />
• Use fault finding tables to identify and locate faults in a<br />
hydraulic system.<br />
MAINTENANCE OF HYDRAULIC SYSTEMS<br />
A hydraulic system is normally easy to maintain. The oil provides<br />
an effective lubricating medium and the relief valves in the<br />
system protect the equipment from mechanical overloading.<br />
The system can be damaged by excessive working pressures,<br />
high operating temperatures and by contamination of the oil.<br />
