Maintenance and service

5.6.1. Checking the knives and knife holders

All knives should have the same lengths and weights. Always check mower before starting work for
damaged, missing and/or worn knives. Replace them, if necessary, only in sets. Make sure all
knives in a set are of the same length and weight.
If the knife holder pin is worn too much and/or the knife holder is worn or deformed, please replace
it immediately.

Fig. 18. Driving chain safety guard.
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.19.)
If the chain becomes loose, please do the following:
Remove the safety guard (fig 18 pos. O.). Loosen self-locking nuts, which hold conditioner's shaft
(fig.19. pos. B.). Tighten the spring by means of the nuts N. After the chain is tensioned, screw all
the bolts. When the tensioner is properly adjusted, a deflection of the chain under finger pressure
should be about 5 mm.
