The electrical system is protected by a fuse which cuts out the entire electrical system if blown.
After
finding and repairing the fault,
replace the fuse with another of the same rating.
Never replace the
fuse with one of a different rating.
The electrical system fuses are underneath the tank (fig. 19). If the
problems persist after all the procedures described above have been carried out, contact the Authorised
After-Sales Service Centre. Never attempt to make difficult repairs unless you have the necessary
equipment and technical expertise.
IMPORTANT!
Take care not to reverse the battery polarity.
Never operate the mower without the battery, since it is equipped with a charge regulator.
Take care not to cause short-circuits.

functions of the machine (e.g. PTO, safety micro-switches).
