Faults and their causes
Never rework the surface of the twine button housing! This
surface has an exactly specified contour. The notch is intentional
and has not been created by wear. Only ever make the
necessary settings by adjusting the string brake and twine button
spring.
1. Threading: Make sure that threading has been performed properly.
The string taking the wrong course is the most common cause of string
breaks (see "Threading diagram" on pages 17-23).
2. String: The machine is set to a certain string thickness. Always use the
same quality and thickness of string in order
to achieve the best results.
a)
String which is too weak often breaks on the twine button
instead of being pulled out without hindrance
b)
If the string is too thick, it will not be released by the knotter
c)
String which is too thin causes a loose knot
3. Twine button: If you are using a good quality of string of the correct
thickness and it still breaks and leaves behind residual fibres in the twine
button, this is generally caused by excessive spring tension on the twine
button.
Reduce the spring tension. Make sure that the setting wheel re-
engages properly and the retainer screw is tightened.
4.
String tension: You achieve the best results with an even, smooth
string brake setting. Check the setting by pulling out a few metres of string
from the tying arm tube. You can change the string tension by turning the
knurled nut on the string brake.
Every person on the user's premises given the task of
setting up, commissioning, operating, maintaining and
repairing this machine must have read and understood
this operating manual, and in particular the chapter
"Safety".
