Caution!
After coupling, carefully check if the driveshaft is well-latched to the tractor
and machine axles. If the moving driveshaft disengages, it can result in a
seriousaccident.
Notes:
The parts cut from the solid and tubular parts of the driveshaft must be the same
length. It is necessary to leave a minimum of 25 mm of play at both ends of the
driveshaft.
The instructions for cutting, lubricating, maintenance, and installing the driveshaft

PICK-UP:
The picking-up of the forage chopper machine must be constant, but based on the operating
capacity of the installed motor, considering the assembly characteristics of the machine and
motor. An excess intake of material will overload the motor and, if the maximum
recommendedamperageisexceededandthiscancauseseriousdamage.

Maintenance
Sharpening the blades
Your Forage Chopper machine requires a minimum amount of maintenance in order to
achieve perfect operation and maximum durability. Therefore, the following are some
importantmaintenancemeasures:
-Cleanthemachineroutinely.
-Keepthemachineproperlylubricated.
-Replacewornordamagedparts.
-Keepthebeltsingoodconditionandproperlystretched.
Duringthefirsthoursofoperation,retightenallthefasteningscrewsandverifythetightnessof
thebelts.
It is essential for the blades to be well-sharpened and
adjusted to the counter-blades, in order to achieve
good quality and efficient cutting. The blades must be
checkdailyandsharpenedwhenevernecessary.
When the machine is turned off, open the housing
coverandcheckallthebladesandwhennecessary:
1-Removealltherotorblades.
2-Thenproceedbysharpeningalltheblades.Keepthe
samecuttingedgeangleastheoriginalandremovethe

Caution!
Before performing any maintenance, adjustment, or lubrication job,
disconnect the motor from the electricity network (in tractor actuation
models,removethekeyfromtheignition).
Wait for all the components to be motionless, before touching any part of the
machine.
Use the same specifications as the original when replacing screws and nuts.

Caution!
Protect the eyes, by wearing safety glasses, when sharpening the blades.
After installing the blades, check if all the fastening screws are tightened. If
