8.1.5 Completing commissioning and run-in period

Property damage caused by low viscosity!
Due to high temperature of the lubricating oil, the viscosity may fall to low values
and cause damage to the product!
Monitor the operating temperature during run-in period, e.g. by measuring the

bearing temperature.
Reduce the load (pressure, speed) of the planetary gearbox if inadmissible

operating temperatures and/or viscosity occur.
Too high operating temperatures indicate faults that have to be analyzed and

eliminated.
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".
For this, put the planetary gearbox out of service. Proceed as described in the

instructions of the machine or the overall vehicle.
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".

8.2 Recommissioning after standstill

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