To remove the blade, hold it firmly wearing
strong gloves and undo the central screw
(1).
Sharpen the two cutting edges using a
medium grade grinding wheel and check
the balance by holding the blade up with a
round 18 mm diameter bar inserted in the
central hole.
To ensure that it works properly without
unusual vibrations any imbalance
between the two parts of the blade must
be below one gram.
This can be easily ascertained by putting
a one gram weight on the lightest end of
the blade. If it tends to go below the bal-
anced position it means that the balance
is correct, while if it stays up then the
other end will have to be made lighter.
