NOTICE
Inspection and maintenance work carried out too late!
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 high pressure cleaning apparatus!
The water jet of a power washer may damage the seals and electrical system of the
radial piston motor!
▶
Do not point the power washer at sensitive components, e.g. shaft seal,
electrical connections and the brake end cover.
For cleaning and care of the radial piston motor, observe the following:
▶
Check whether all seals and fittings on the connections are securely seated
to ensure that no moisture can penetrate into the radial piston motor during
cleaning.
▶
Use only water and, if necessary, a mild detergent to clean the radial piston
motor. Never use solvents or aggressive detergents.
▶
Remove coarse external dirt and keep sensitive and important components, such
as solenoids, valves, indicators and sensors, clean.
10.2 Inspection
In order to ensure long and reliable operation of the radial piston motor, Bosch
Rexroth recommends regular monitoring of the hydraulic system and radial piston
motor. The inspection schedule in Table 11 should be followed and the results
documented and archived:
Table 11: 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.
Yearly or every 1000
