Changing oil in planetary gear unit
$
First oil change after 250 hours of run-
ning-in period, thereafter every 1000
hours, but at least once a year.
To drain the oil, turn the drain screw (2)
into its 6 o’clock position, ensuring that
the filler screw (1) is in its 9 o’clock posi-
tion.
$
Always perform oil changes with the oil
at operating temperature, immediately
after the gearbox comes to a standstill.
This ensures that suspended particles of
solid matter do not have time to settle
and form sediment.
Wear protective clothing when draining
hot oil. Health hazard caused by contact with the skin.
- Unscrew the oil drain screw (2), collect draining oil.
- To bleed the system, unscrew the filler screw (1).
- Once the oil has drained off completely, fasten the drain screw (2) back into place.
- Top up oil through the opened filler screw until a small amount of oil emerges from
the screw plug bore.
- Properly screw in the filler screw (1) again.
