tes.

DEFECT
6)
Blade balancing is more important than its
sharpness. An unbalanced blade causes early
wear of all engine and machine parts. This
type of damage is not covered by warranty.
The same holds true for loose fixing bolts which,
in addition to being dangerous for the operator,
will surely cause breakages not covered by
warranty.
7)
During machine cleaning and maintenance
operations, avoid inverting the engine with head
(spark plug side) facing downward. Avoid
operating the machine with the engine head
turned downward. On some versions of
equipment, the engine’s position at standstill
is with head facing downward; we suggest
positioning the machine with the engine level
in order to avoid this inconvenience. The
defect is not covered by warranty. When
performing any under-body work, lift the
machine so that the carburettor is the highest
part of the machine.
