10 Maintenance and repair

10.1 Cleaning and care

Damage to surface!
Aggressive solvents and detergents may damage the seals on the hydraulic motor
and cause them to age faster.
▶ Never use solvents or aggressive detergents.
▶ If in doubt, check the compatibility of the detergent with the seal type (Nitrile or
Viton) specified in the hydraulic motor.
Damage to the hydraulic system and the seals!
Using a high-pressure cleaner could damage the speed encoder and the seals of the
hydraulic motor.
▶ Do not point the high-pressure cleaner at sensitive components, e. g. shaft seal,
seals in general, electrical connections and speed encoder.
For cleaning and care of the hydraulic motor, observe the following:
1.
Plug all openings with suitable protective caps/devices.
2. Check whether all plugs and plug seals are securely seated to ensure that no
moisture can penetrate into the hydraulic motor during cleaning.
3. Use only water and, if necessary, a mild detergent to clean the hydraulic motor.
4. Remove coarse dirt from the outside of the motor and keep sensitive and
important components, such as sensors and valve blocks clean.

10.2 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 10.2.2: Oil maintenance
• 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 16: Maintenance chart.
