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) specied 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.
