Malfunction
Cause and/or remedy
Knots only in the twine strand that runs over the
upper bale side.
1.
Incorrect position of knotter needle — change seating
of knotter needle on the yoke.
2.
Incorrect position of twine bar — adjust the position of
the twine bar on the knotting mechanism.
3.
Incorrect swivel range of the twine bar — adjust the
linkage to the twine bar.
4.
Broken or deformed retainer springs in the knotting
mechanism — replace springs.
5.
Not enough twine tension — tension the twine brake
springs.
No knot or a knot with very short ends that
usually slip through the knot loop.
1.
Not enough tension on the knotter hook closer —
tension closer for knotter hook.
2.
Knotter hook worn — replace knotter hook.
3.
Too much tension on the twine retainer — reduce
tension on springs by loosening the hexagonal head
screws.
Knots are left hanging on the knotter hook.
1.
Too high tension on the knotter hook closer — release
closer for knotter hook.
2.
Too much distance between the extractor comb on the
blade lever and the back of the knotter hook — align
the blade lever with a light tap of the hammer.
3.
Surface of the knotter hook is rough — replace the
knotter hook.
4.
Incorrect setting for the twine bar — correct it.
5.
If the scraper path of the blade lever is not long
enough (the blade lever can be deformed by a dull
twine blade) — remove the blade lever and align it, or
replace it if necessary. Check the cams on the knotter
disc for wear and replace the disc, if necessary.
6.
Twine tension too low — increase the baling density.
Set the twine brakes on the twine box (1 - 2
revolutions), increase the baling length.
