Grinding and balancing of blades
Remove the blades according to the decription in
the previous section.
Clamp the blade in a screw vice and file it so that
it becomes sharp.
Balance the blade as follows:
Fix, for example, a mandrel horizontally in a
screw vice according to the diagram.
Push the blade onto the mandrel via the hole in
the centre of the blade and check that the blade
balances evenly. The diagram shows a blade
which needs to be adjusted, it must be ground
further to obtain the correct balance (at the
arrow).
Installation is carried out in the reverse removing
order.
WARNING!
When working with the blades,
use protective gloves.
IMPORTANT INFORMATION
The friction washer must be replaced
when replacing the shear pin.
