10.3 Maintenance schedule planetary gearbox
The material number-specific operating instructions may include a maintenance
schedule which is different from the maintenance schedule in the general
operating instructions. The maintenance schedule in the material number-
specific operating instructions always applies.
 Check whether there is a different maintenance schedule for your planetary
gearbox in the material number-specific operating instructions.
 The maintenance schedule, shown in table 6 “Maintenance schedule planetary
gearbox” only applies for the planetary gearbox. Therefore observe not only
with the maintenance schedule of the planetary gearbox but also with the
maintenance schedule included in the machine/vehicle manufacturer's
operating instructions.

10.4 Maintenance
If used in accordance with the intended purpose, the planetary gearbox is low-
maintenance.
The service life of the planetary gearbox essentially depends on the quality of its
lubricating oil. We therefore recommend changing the lubricating oil at least once
a year or every 1,500 operating hours (whichever is earlier).
10.4.1 Approved lubricating oils
Fill the planetary gearbox HYDROTRAC GFT 8000 only with lubricating oil which
has been approved for this planetary gearbox according to the selection list –
industrial gear oils in appendix B "Required and supplementary
documentations" in the material number-specific operating instructions for
these planetary gearbox.
