Checking of oil level in gearbox
Remove the dipstick from the housing of the gearbox.
Clean the dipstick and position it again into the opening,
so as to verify the level of the lubricant.
If the level is too low, fresh lubricant must be added
through the opening for the dipstick. See page 14 for
the specifications of the lubrication oil for your gearbox.
As regards the maintenance of the gearbox, please con-
sult the owner's manual, provided by the manufacturer
in question..

Gearbox oil
Draining the oil from the gearbox
First remove either the dipstick or the filler cap, depen-
dent on the gearbox model. Position the hose of the spe-
cial sump pump into the pipe of the dipstick. Extract the
oil from the gearbox by quickly pushing down the grip of
the sump pump and then pull it slowly upwards.
If there is sufficient space below the bottom of the gear-
box, you may also remove the drain plug of the gearbox,
for letting the oil out. In both cases collect the oil in a
bowl and treat it in accordance with the environmental
directives in your country.
Adding oil
Fill the gearbox with its lubricant through the hole of the
dipstick, or via the filler cap, if available (dependent on
the model of gearbox). Please consult the owner's ma-
nual, provided by the manufacturer in question.
