Gearbox

When servicing the gearbox, the sealing of the
casing must be restored. To do so, apply a
layer of silicone to the casing before closing it.
Allow the silicone to cure for at least 24 hours
before filling it with oil.
Oil Level – Oil Filling
(Figure 11)
To check oil level: Remove oil level plug, check
if the oil is flush with the plug. If not, remove
the oil filler plug and fill until the oil flows
through the oil level plug hole. Reinstall both
plugs.
