Check springs for
correct length
The length of the springs from locking bolt to locking bolt must be 70
cm. This results in maximum spring tension. Over time, the spring ad-
justment can change gradually and needs to be corrected.
Check the spring length every year.
Adjust the length if it is shorter or longer than 70 cm.

Align bodies
New ploughs are delivered with correctly adjusted bodies. Use of the
plough can gradually alter the alignment. Therefore the alignment of
the bodies must be checked after every ploughing season
The bodies are correctly aligned when
•
A2 = A1
•
B2 = B1
•
A2 = B2
The maximum permitted deviation between A1 and A2 is 5 mm. When
there is greater deviation, adjust the bodies with the nuts on the sup-
ports.
Start with the middle bodies.
Loosen the counter nut
Adjust the nut until the body is in the desired position
Tighten all nuts, including the counter nut
Continue with the other subsequent bodies.
