11. Inspection and Maintenance
11.1 General Information
All service and maintenance work must only be carried out by qualified personnel.
See
Section 3
.
Conversions and Changes.
When carrying out service and maintenance tasks, the gearbox must always be shut down.
The input must be secured against any unintentional start-up (key switch, lock) and an information sign must be
affixed with the information that work is being carried out on the gearbox.
Warning
Major risk of injury due to accidental start-up of the input unit.
Before starting any maintenance work, secure the gearbox against any start-up.
Warning
Major risk of injury
from disassembly of transmission parts (couplings, cardan
shafts, belts, etc.) as long as torsional forces are still acting on the gear shafts.
Secure gear shafts against torsional forces and disassembly transmission
elements.
11.2 Maintenance Periods
If maintenance periods are not complied with, major damage may be caused to the gearbox and within the
plant. Therefore it must be ensured that these maintenance periods are observed.

Every 4 years or 20,000 operating hours
Section 11.3
Checking the gearbox condition
Every 2 years
Section 11.4
11.3 Oil Service Life
The oil service lives at a mean oil temperature of 80°C in the gearbox without any serious change in the oil
qualities are specified by the oil manufacturers as minimum values:
•
For mineral oils, biodegradable oils and physiologically harmless oils 2 years or 10,000 operating hours
•
For synthetic oils (polyalphaolefins and polyglycols) 4 years or 20,000 operating hours
Note on oil service life
The actual relevant oil service lives may be longer, but also shorter for operating temperatures in excess of
80°C. Here, the rule applies that a temperature increase by 10°C approximately halves the service life of the
oil.
