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 screws and fittings, replace
faulty seals and keep the drive clean.
▶ Inspect tank, pumps, motors and filters (e.g. air-, oil-, magnetic filters etc.),
clean or change if necessary. Replace all filter cartridges for which a filter
clogged indication has been given.
▶ Check the pressures and temperatures in the hydraulic system and carry out
routine operations. Adjust valves etc. if necessary.
▶ Check the hydraulic fluid; see chapter
.
▶ 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
▶ Check torque arm and pivoted attatchment.
