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 balanced position it means that the balance
is correct, while if it stays up then the other end will have to be made lighter.
! WARNING! A damaged or bent blade must always be replaced;
never try to repair it! ALWAYS USE MANUFACTURER'S GENUINE SPARE
BLADES !
! WARNING! When re-fitting the
blade, always follow the indicated
sequence, making sure that the
blade’s wings are facing towards the
interior of the cutting deck and that
the concave part of the cup spring
(1) is pressing against the blade.
Fully tighten the fixing screw (2). If
the shaft hub (3) came off when dismantling
the blade, make sure that
the key (4) is firmly in its right position.
