Completing Commissioning And Run-In Period; Recommissioning After Standstill - Bosch rexroth HyDrotrAC GFt Operating Instructions Manual

8.1.5

Completing commissioning and run-in period

property damage caused by low viscosity!
Due to high temperature of the hydraulic fluid/lubricating oil, the viscosity may fall
to low values and cause damage to the product!
f Monitor the operating temperature during run-in period, e.g. by measuring the
leakage fluid temperature (axial-piston motor)
f Reduce the load (pressure, speed) of the axial-piston motor of the planetary
gearbox if inadmissible operating temperatures and/or viscosity occur.
f Too high operating temperatures indicate faults that have to be analyzed and
eliminated.
f Check after approx. 10 hours of full load operation that all mounting screws
are tightly secured. Proceed as described in chapter 10.2.4 "Checking and
retightening screw connections".
f For this, put the planetary gearbox out of service. Proceed as described in the
instructions of the machine or the overall vehicle.
f After reaching the operating temperature, check that the planetary gearbox
does not show any leakage. The maximum operating temperature is 90 °C.
This test can be performed during operation. Proceed as described in chapter
10.2.1 "Visual inspections".

reCoMMiSSioninG AFter StAnDStiLL

Depending on the assembly and ambient conditions, certain changes in the
hydraulic system can make recommissioning necessary.
The following criteria may make recommissioning necessary:
• Air and/or water in the hydraulic system
• Aged hydraulic fluid
• Other contaminations
f Proceed for recommissioning as described in chapter 8.1 "Initial commissioning".
