SAFETY MECHANISM FOR OVERLOADING AND FOREIGN BODIES
1. The round baler is provided with a
cardan drive shaft with torque limiter: in
case of overload, it shears off the
safety bolt preventing any parts from
breaking (Fig. 10).
2. A second system similar to the first, is
located on the primary transmission,
which is equipped with a safety
bolt M7 x 50 – class 8.8 - R = 80
kg/mm
2
(no. 12 Fig. 8/A).
This device works when rocks or other
foreign bodies get into the pick-up /
packer device, or when there is any
abnormal resistance to rotation of the
lower rollers. Mainly it is due to the
intrusion of foreign bodies or to too high
pressure in the compression chamber.

WARNING!
Only replace with safety bolts identical to the original one. The bolts M7 x 50 – class 8.8 - R = 80 kg/mm² are provided (12
pcs.)

MAINTENANCE, LUBRICATION AND GREASING
WARNING!
•
Before performing any maintenance or lubrication, put the safety mechanisms of the round baler (Fig. 12) into operation
and proceed only after turning off the engine.
•
Turn off the engine, remove the keys from the ignition and disconnect the machine before proceeding with operations of
maintenance, cleaning and repairs.
•
Always use the blocking or locking devices before performing any maintenance or repairs.
•
Wear gloves and use the proper tools when replacing any parts. Also, for the stability of the machine, it is advisable to
perform all operations on a solid support.
•
Replace any protection mechanisms that are not adequate and remove any oil or grease at once.
•
It is very important to clean the machine at the end of every working days by using a pistol of an air compressor
giving particular attention to the area between the back of the pick-up and the frame of the packer device and
also the side frame of the round baler (see fig. 12/A).
•
If it is necessary to do any electrical welding on the machine-tractor unit, remember to detach both the generator cable
and the battery.
•
Make sure the replacement parts are original, that is, the ones used by the manufacturer, and check before using them
that all the screws are tight so that they won’t come loose.
