® SAQ4
A linear actuator will only move slowly when the control
lever is operated.
Using the fault finding tables make a list of the possible
causes.
SUMMARY
You have now completed Segment Six but a reminder of the
aims for this segment would not be out of place.
• State the key maintenance problems which can arise in a
hydraulic system.
• State the items of maintenance which should be carried out
regularly.
• Describe simple maintenance procedures.
• Use fault finding tables to identify and locate faults in a
hydraulic system.
You have also achieved Objectives No. 5 and 6 on page xiii and
have worked well. If you have checked your responses to the
SAQ's you have also completed the module and I hope you have
found it both useful and interesting. It does not cover all that is to
be known about hydraulic systems in fishing vessels but should
help you to keep the systems on your vessel in working order
and trouble free.
