Damage to equipment.
▶ Carry out the specified inspection and maintenance work at the intervals
described in this manual.
10.1 Cleaning and care
NOTICE
Damage to seals and electrical system by mechanical effects!
The water jet of a power washer may damage the seals and electrical system of the
axial piston unit!
▶ Do not point the power washer at sensitive components, e.g. shaft seal,
electrical connections and components.
For cleaning and care of the axial piston unit, observe the following:
▶ Check whether all seals and plugs of the plug connections are securely seated to
ensure that no moisture can penetrate into the axial piston unit during cleaning.
▶ Use only water and, if necessary, a mild detergent to clean the axial piston unit.
Never use solvents or aggressive cleaning agents.
▶ Remove external coarse dirt and keep sensitive and important components,
such as solenoids, valves and sensors, clean.
10.2 Inspection
In order to enable long and reliable operation of the axial piston unit, Bosch Rexroth
recommends testing the hydraulic system and axial piston unit on a regular basis,
and documenting and archiving the following operating conditions:
Table 17: Inspection schedule
Task to be carried out Interval
Hydraulic
system
Check level of hydraulic fluid in the reservoir. Daily
Check the operating temperature at a comparable load
condition at the reservoir port and in the reservoir.
Weekly
Conduct analysis of hydraulic fluid: viscosity, aging and
dirt contamination
Yearly or every
2000 operating
hours (whichever
occurs first)
Check filter.
The change interval may vary depending on the degree
of contamination of the hydraulic fluid. We recommend
using a contamination indicator.
