Setting the holding force of the twine retainer
The type and moisture content of crops, its baling density as well as the tying twine that is
selected all require different settings, which have to be determined by trial and error under
actual working conditions. The twine retainer (1) should only clamp the twine securely enough
so that it is not pulled out of the twine retainer mechanism during the tying process. If the
clamping effect is too great, it will tear the twine into shreds.

The holding force is preset in the factory. The twine retainer spring (3) must never be pre-
tensioned to block length.
Ensure stronger or weaker pre-tensioning of the twine retainer springs (3) with nut (2)
(approx. half a turn).

Setting the blade lever
BP000-202
The blade lever (1) must be aligned so that the billhook (3) can turn freely without touching the
blade lever.
However, the scraper comb (2) of the blade lever must slightly and evenly touch the back of the
knotter hook (3). In the blade lever dead-centre position, the distance between the scraper
comb of the blade lever and the billhook tip should be
X=15–18 mm
. The blade lever has
reached the dead-centre position when the blade lever roll has reached the highest point on the
cam (4) in the knotter disc (5).
