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.
IMPORTANT INFORMATION
When the blades on a BioClip deck are
removed the friction washer positioned
between the blade and nut must be
replaced.
