Maintenance
All maintenance, cleaning and repair operations must be car-
ried out with the machine firmly lowered to the ground and
detached from the tractor, or with disconnected PTO, engine
off and starting key out.
The time of maintenance is defined according to the normal
use of the machine. If the machine is used in very hard condi-
tions, the time between maintenance operations must be
shorter.
Take care that grease nipples on the machine are always clean.
After each maintenance operation check that all guards are fit-
ted on the proper place.
Oil control in gearbox
Use always the same type of oil, SAE 90. To change the oil first unscrew the
plug under the gearbox
(Fig.21/1)
and let the oil off. Use the hole on the
top of gearbox for filling in
(Fig. 21/2)
and on the top of the half axle
(
Fig.22/1 )
. For pouring in use a funnel.
Pour in the oil till the level of the
control plug on the half axle
(Fig.22/2
) and on the head of the gearbox
(Fig.21/2).
The control plug on the head of the gearbox is placed under the
PVC shield
(Fig.21/3).
