10 Maintenance and repair

10.1 Cleaning and care

NOTICE

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 sensor and the seals of the
hydraulic motor.

▶ Do not point the high-pressure cleaner at sensitive components, e. g. shaft

seals, seals in general, electrical connections, speed sensors and valves.

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 during cleaning.

Use only water and, if necessary, a mild detergent to clean the hydraulic motor.

Remove coarse dirt from the outside of the motor and keep sensitive and
important components, such as sensors and valve blocks clean.

10.2 Inspections

10.2.1 Magnetic plug inspection

A magnetic plug is installed in the drain connection. By regulary inspecting
the magnetic plug a malfunction of the hydraulic system can be detected and

corrected.

Insert

NOTICE

Contact of hydrauic fluids!

Risk for injury.

▶ Only remove the magnet.

▶ Oil leakage if insert is removed when the motor case is pressurised.
