Belt Replacement And Tension Adjustment; Lubrication; Recommended Lubricants; After The First 8 Hours Service - breviglieri jet 50sr Manuel D'utilisation Et D'entretien

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 indicative
and refer to normal conditions of use.
They may therefore vary depending on the type of service, whether
the environment is dirty or not, seasonal factors, etc.
The servicing operations must obviously be carried out more fre-
quently 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.
5.1.1 BELT REPLACEMENT AND TENSION
ADJUSTMENT
The belts are correctly tightened when they give max 10 mm (Fig.
14).
Proceed in the following way to replace the belts and adjust their
tension:
- remove the protective casing by loosening the bolts (1 and 2
Fig. 11);
- loosen the bolts (1 Fig. 12) of the driving pulley plate;
- loosen the check nut of the adjuster screw (2 Fig. 12);
- use the adjuster screw (2 Fig. 12) until the correct belt tension
has been obtained;
- tighten the check nut of the adjuster screw (2 Fig. 12);
- tighten the bolts (1 Fig. 12) of the driving pulley plate;
- fit the protective casing back in its correct position.
The transmission components from the overdrive to the pulley
must be aligned after the belt tension has been adjusted.
Loosen the overdrive bolts (1 Fig. 13), lift or lower the overdrive
itself so that the transmission is parallel to the machine, then
retighten the bolts (1 Fig. 13).
Check the planarity of the two pulleys when the belts are regu-
lated or replaced. Place a metal straightedge on the surfaces of
the two pulleys, as illustrated in Fig. 15. The surface of the straight-
edge must adhere in all the four points (1) indicated in Fig. 15.

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 systematically and at
the required intervals.
The frequencies given refer to machine use in a normal environ-
ment. If this machine is used in heavier duty conditions, it must
naturally be lubricated more frequently.

5.2.1 RECOMMENDED LUBRICANTS

- For the overdrive unit, it is advisable to: OLIO SAE 85W/140 or
an equivalent type complying with API-GL5/MIL-L-2105C.
- For all greasing points, the Manufacturer recommends: LITHIUM
GREASE or an equivalent type.
When servicing the driveline, strictly comply with the instructions
given by the driveline Manufacturer, in the specific operation 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.
- After you have checked the hammers/knives for wear, fully
tighten the screws that fix them in place.
- Check to make sure that all the bolts on the machine are tight.

5.2.3 EVERY 20 HOURS SERVICE

- Make sure that the screws that fix the hammers/knives are well
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 overdrive housing. If necessary,
top it up through the plug on the top of the gearbox (1 Fig. 16).

5.2.5 EVERY 500 HOURS SERVICE

- Change the oil in the overdrive housing after every 500 hours
service or at least once a year.

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:
- Wash all fertilizers and chemical products from the machine
and dry it.
- Carefully check the machine and replace any damaged or worn
parts.
- Fully tighten all the screws and bolts, particularly the ones that
fix the tines.
- Thoroughly grease the machine and then cover it with a tar-
paulin and store it in a dry place.
If these operations are carried out with care, it will be all to the
user's advantage as the machine will be in optimum conditions
when needed again.
If these operations are carried out with care, it will be all to
the user's advantage as the machine will be in optimum con-
ditions when needed again.
If the machine must be dismantled, comply with the anti-pol-
lution laws in force. Old lubricants must and the various com-
ponents must be disposed of according to their different
structures.
