6.2 ROUTINE MAINTENANCE
Respect the manufacturer’s routine maintenance schedule to keep the gearbox at peak efciency.
Good maintenance ensures maximum gearbox performance, extended service life and continued
compliance with safety regulations.
List of routine checks
We recommend keeping a checklist of inspections so that any changes in individual control parameters can
be identied rapidly and easily.
The times indicated in the following tables vary signicantly in relation to the conditions of use of
the gearbox and must be construed as valid in the absence of other types of problems.
Depending on the temperature reached by the lubricant, it should be replaced at the intervals indicated in
the table below.
