The blade is made of hardened steel. To get a clean job, sharpen the
blade frequently, about every 25 hours of use. Make sure the blade
is always well balanced.
Insert a small iron pin (2 or 3 mm in diameter) into the hole in the
middle of the blade: it must remain horizontal. If the blade does not
stay horizontal, balance it by sharpening it further on the side
where it is leaning.
WARNING: Use only original spare parts. Poor quality replacement
parts can cause serious damage to your mower and affect your
safety. Contact our service agent to get specifications about the
correct original spare parts.
To remove the blade, loosen the screw, check the blade bracket,
and replace all parts if they are worn or damaged.
To sharpen the blade, place it in a clamp and file the sharp edges
evenly, checking the balance of the blade.
When reassembling the blade, make sure that the cutting edges are
in the same direction as the direction of rotation of the motor. The
tightening torque of the blade screw should be 3.7 kg * m / s 2 (37
Nm) and can be checked with a torque wrench.
g. Adjust the carburettor
The carburettor has been factory set for optimum performance. If later
adjustments are necessary, have them performed by a specialist.
