CAUTION:
If the knife is missing or disc cover plate is damaged the vibrations may
occur, which leads to cutterbar's damage. In that case warranty claim will be
revoked.
If the disc or disc cover plate is damaged, the whole set must be immediately
replaced (2 knives i 2 cover plates) with new genuine ones.

6.9.2. Checking the V-belts tension

Check the V-belt tension. V-belts are tensioned with spring tensioner (Fig. 29) equipped with
checking plate. Distance S between plate tip and holder should be 10 mm. If the gap is wider the
V-belts will be looser. Tensioning is done by nuts N. When any of the belts are damaged,
the complete set must be replaced.

6.9.3. Checking the tension of tine and roller conditioners' driving chain

Drive from PTO shaft is transmitted by means of driving chain on the conditioner.
The tensioner provides the constant tension of the chain and is regulated by the nut N (Fig. 30b)
Tighten the chain by means of a nut N. The tension of the chain can be checked through
the window O (Fig. 30a). To check the tension thoroughly, please remove the safety guard
(Fig. 30a) after unscrewing four bolts S. A deflection of the properly tensioned chain under finger
