Action
Inspect the oil level in the hole for the oil plug, filling
and inspection.
The oil should reach all the way up to the external
edge of the thread for the oil plug, filling and inspec-
tion.
Note
If the oil plug, draining is not opened, then use a
clean, narrow object, for example an oil stick or a
cable tie, to gently poke the oil surface. This will
avoid surface tension from stopping air to enter into
the gearbox.
Adjust the oil level, if required.
Refit the oil plugs.
WARNING
Do not mix oil types! If wrong oil is refilled, the
gearbox must be rinsed as detailed in Technical
reference manual - Lubrication in gearboxes.

make sure that the oil plug, filling and inspection
is facing upwards.
