4.4 Periodic maintenance
When a hydraulic system has been in service
for some time, it must undergo periodic mainte-
nance 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, replace faulty seals and
keep the drive clean.
- Inspect and clean all air, oil and magnetic
filters; replace all filter cartridges for which
a filter clogged indication has been given;
inspect tank, pump, filters etc. and clean if
necessary.
- Check the pressure and temperature of the
hydraulic fluid and carry out routine opera-
tions. Adjust valves etc. if necessary.
- Check the hydraulic fluid; see the Section
headed "Oil".
- Check 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 are as
follows:
Rpl = Replacement Insp = Inspection
Ctrl = Control of braking torque

4.4.1 Cleaning and care
Damage to the surface caused by sol-
vents and aggressive detergents!
Aggressive detergents may damage the seals
on the hydraulic motor and cause them to age
faster.
- Never use solvents or aggressive deter-
gents.
- If in doubt, check the compatibility of the
detergent with the seal type (Nitrile or Vi-
ton) specified in the hydraulic motor.
Damage to the hydraulic system and
the seals!
Using a high-pressure cleaner could dam-
age 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:
- Plug all openings with suitable protective
caps/devices.
- Check whether all plugs and plug seals are
securely seated to ensure that no moisture
can penetrate into the hydraulic motor dur-
ing cleaning.
- Use only water and, if necessary, a mild
detergent to clean the hydraulic motor.
- Remove coarse dirt from the outside of the
machine and keep sensitive and important
components, such as sensors and valve
blocks clean.
