PROBLEM
CAUSE REMEDY
ELECTRICAL SYSTEM
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 on the left-hand side of the steering wheel (fig. 23).
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.
