10.3 Maintenance plan
When a hydraulic system has been in service for some time, it must undergo periodic
maintenance and servicing at intervals which depend on the equipment and the type
of duty. This periodic maintenance must include the following operations:
•
Check the hydraulic system for leakage. Tighten the screws, fittings, replace faulty
seals and keep the drive clean.
•
Inspect tank, pump, filters (e.g. air-, oil-, magnetic filters etc.) and clean or change
if necessary. Replace all filter cartridges for which a filter clogged indication has
been given.
•
Check the pressure and temperature of the hydraulic fluid and carry out routine
operations. Adjust valves etc. if necessary.
•
Check the hydraulic fluid; see chapter
10.4.2
.
•
Make sure that no dirt or other contaminations enter the system during inspection.
Check that the outside of the hydraulic motor in an installation is kept free of dirt,
thus leakage and faults will be detected earlier.
• We recommend that a running log be kept and that planned inspections are carried
out at set intervals.
• Maintenance checks and operations, see
Table 19
.
• Check torque arm and pivoted attatchment.
