Balance the blades by:
• Attaching a mandrel, for example, horizontally in
the vice as shown.
• Thread the hole in the centre of the blade over
the mandrel and make sure that the blade is
equally weighted. The illustration shows a blade
that needs to be adjusted, it must be filed more
so as to attain the right balance (at the arrow).
• Assemble in the reverse order as described for
dismantling.
IMPORTANT INFORMATION
When the blades on the mulching unit
have been removed, the friction washer
located between the blade and nut must
be replaced.
