Tighten the 3 screws. Use of electric powered screwdrivers is not recommended.
HOW TO SHORTEN THE DRIVE SHAFT
Bondioli & Pavesi advises against altering its products. If modifications are required,
we recommend that you consult your implement dealer or a qualified service center
before proceeding. If the driveline is too long adopt the following procedure.
Remove the shielding.
Shorten the drive tubes by the required length.
Telescoping tubes must always overlap by at least 1/2 of their length in
normal operation and at least 1/3 of their length in all working conditions.
During maneuvers, when the driveline is not rotating, the telescoping tubes must
have a suitable overlap to maintain the tubes aligned and allow them to slide freely.
Carefully deburr the ends of the tubes with a file and remove all filings from
the tubes.
Shorten shield tubes one at time by cutting the same length that was cut
from the drive tubes.
Grease the internal drive tube and reassemble the shielding on the driveshaft.
Check the length of the driveshaft at its minimum and maximum extensions
on the implement.
