NOTICE
Inspection and maintenance work 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 influences!
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, for example,
shaft seal, electrical connections and components.
For cleaning and care of the axial piston unit, observe the following:
▶
Check whether all seals and plug-in 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, displays 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 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)
