Grinding and balancing of blades

WARNING!
When working with the blades,
use protective gloves.
1. Remove the blades according to the
decription in the previous section.
2. Clamp the blade in a screw vice and file it so
that it becomes sharp.
3. 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 remo-
ving order.
WARNING!
If the blades are cracked,
whether caused by poor repair
or other damage, they could
break while being used. The risk
increases if the blades are
poorly balanced.
