If the machine is to remain idle for a long period of time, lubri-
cate the parts subject to wear and store the machine in a dry,
sheltered place, covered with a plastic sheet.
This will ensure that the machine is in the ideal condition
when required again.
SECTION 5
Maintenance
5.1 ROUTINE MAINTENANCE
The various routine maintenance operations are described be-
low. Remember that lower running costs and longer machine life
depend on continual compliance with these instructions.
WARNING
Before proceeding with any operation, make sure that the
machine is parked on a flat surface. Prevent it from moving
by placing chocks under the wheels.
Servicing, adjusting and the operations required to prepare
the machine for work must be carried out with the tractor
and the driveline detached from the machine.
The servicing frequencies indicated in this manual are in-
dicative and refer to normal conditions of use. They may there-
fore vary depending on the type of service, whether the envi-
ronment is dirty or not, seasonal factors, etc. The servicing
operations must obviously be carried out more frequently in
heavier duty service conditions.
- Before injecting lubricating grease into the grease nipples,
carefully clean these latter to prevent mud, dust or foreign
bodies from mixing with the grease as this would reduce
or even annul its lubricating effects.
Injection into the greasing points of a large quantity of
grease at high pressure can damage the bearing protec-
tion. This operation must therefore be carried out with the
greatest care.
- Lubricate and grease all the required points, including the
chains.
- Use oil of the recommended type for topping up and
changes.
Keep all lubricants well away from children's reach.
Carefully read the warnings and precautions on the lubricant
containers.
The operator should thoroughly wash himself after using lu-
bricants.
Dispose of used oil in compliance with the anti-pollution laws.

5.2 LUBRICATION
Lubrication of any machine with parts that turn and/or rub together
is a vitally important task for the life and functionality of the actual
machine itself. Lubrication must therefore be carried out system-
atically and at the required intervals. The frequencies given refer
to machine use in a normal environment. If this machine is used
in heavier duty conditions, it must naturally be lubricated more
frequently.

The indicated quantities correspond to a level about 1 cm below
the upper edge of the gears in the casing when the machine is on
a flat surface.
5.2.1 RECOMMENDED LUBRICANTS
- COLUMBIA V.V. Gear EP 460 or AGIP ROTRA MP SAE 85W/
140 oils are recommended for the gearboxes (6 l.).
- AGIP GR MU EP 2 GREASE or an equivalent type is recom-
mended for all greasing points.
When servicing the driveline, strictly comply with the instruc-
tions given by the driveline Manufacturer, in the specific opera-
tion and maintenance manual with which each driveline is
equipped.
5.2.2 AFTER THE FIRST 8 HOURS SERVICE
Each new machine must be checked after the first 8 hours serv-
ice. proceed in the following way:
- Check the general condition of the machine.
- Fully tighten the blade screws after having checked the blades
themselves for wear.
- Check to make sure that all the bolts on the machine are tight.
5.2.3 EVERY 20 HOURS SERVICE
- Make sure that the blade screws are fully tightened.
- Grease the driveline, the roller adjuster screw and the roller
supports.
5.2.4 EVERY 100 HOURS SERVICE
- Check the level of the oil in the central distributor/reduction unit
housing. Top up if necessary.
- The level of the oil is correct when oil starts to come out of the
hole in the oil drain cap (Fig. 11).
5.2.5 EVERY 500 HOURS SERVICE
- Change the oil in the central distribution/reduction unit hous-
ings after every 500 hours service or at least once a year.
- Check to make sure that the driveline clutch is fully efficient.
Have the clutch overhauled and the plates replaced by a spe-
cialized workshop if necessary.
5.3 PREPARING FOR STORAGE
Proceed with the following operations at the end of the season or
if the machine is to remain idle for a long period of time:
