6.2. Tensioning the net cutting knife
The net cutting knife is automatically tensioned (reset) each
time the tailgate is opened. If a new net wrapping is required
without opening the tailgate while the bale chamber is full, due
to a net changeover or fault, the tensioning process can be
done manually.
This is done by pulling the knife holder forwards against the
spring (fig. 39). It can be released as described in the Section
“Wrapping.”
6.3. Setting the net wraps
With help from the scale (fig. 40), a variable number of net
wraps around the roll bales can be set.
After loosening the wing nut, the net length can be set by
moving the nut within the slot.
Tip:
First, select the setting in the centre of the slot. To save binding
material, adjust stepwise in the ( - ) direction for the following
bales.
However, the bales must still be held together securely. With
very smooth material and a high pressing density, a greater
amount of net may be needed.
