1.12 Springs
– pretensioning of cutting blades – adjustment
NOTE!
If the pretension of the cutting blades is too high, there is a risk of accidents and
of the device breaking. The sprung cutting blades are a safety arrangement, and
they are intended to make ploughing safe. If any of the springs has become deformed or
broken off, we recommend that all the springs on the blade be replaced, art. no. 200595.
The default pretension, i.e. spring Y dimension, is 330 mm
– see Figure 20.
To increase the pretension, adjust Y dimension as follows:
1) Loosen nuts M1 and M2 in the lower part of the spring
– see Figure 20
2) Tighten nut M1 upwards two turns at a time and test operate. Repeat until the tension
is just right
– see Figure 21
3) Tighten nut M2 against nut M1 to lock the spring
– see Figure 22
NOTE!
If the pretension of the cutting blades is too low, the cutting blades constantly
give way, the ploughing results are poor, the plough jumps and causes
unnecessary noise.
To decrease the pretension, adjust Y dimension as follows:
4) Loosen nuts M1 and M2 in the lower part of the spring
– see Figure 22
5) Tighten nut M2 downwards
– see Figure 21
6) Tighten nut M1 downwards two turns at a time and test operate. Repeat until the tension
is just right
– see Figure 21
7) Tighten the lower nut M2 against nut M1 to lock the spring
– see Figure 20
