10 Maintenance and repair
NOTICE
Inspection and maintenance overdue!
Risk of property damage.
▶
Perform 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 due to mechanical forces.
The jet of a high-pressure cleaner may damage the seals and electrical system of
the axial piston unit.
▶
Do not point the high-pressure cleaner 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 fittings on the 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 cleaning agent to clean the axial piston
unit. Never use solvents or corrosive cleaning agents.
▶
Remove major external contamination and keep sensitive and important
components, such as solenoids, valves and sensors, clean.
10.2 Inspection
In order for the axial piston unit to be reliable and long-lasting, Bosch Rexroth
recommends testing the hydraulic system and axial piston unit on a regular basis,
and documenting and archiving the following operating conditions:
Table 12: Inspection schedule
Task to be performed
Interval
Hydraulic system
Check level of hydraulic fluid in the reservoir.
Daily
Check the operating temperature under comparable load
condition at the drain port and in the reservoir.
Weekly
Conduct analysis of hydraulic fluid: Viscosity, aging and
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.
Yearly or every
1000 operating
hours (whichever
occurs first)
