– Blades fault
– Blades unbalanced
– Fastenings are loose
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!
– Pay attention 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.
THE MACHINE DOES NOT REMAIN IN NEUTRAL
Adjust the device (fig. 24) by loosening the counter-nut and using the central screw.
FORWARD LEVER
To adjust the forward and reverse travel speeds, use the screws (fig. 25, ref. A) if the forward lever
automatically returns to zero adjust the self-locking nut (fig. 25, ref. B).
END OF WORK
After mowing, disengage the blades and drive back to base with the cutting deck in the highest position.
To stop, move the travel lever to the STOP position (fig. 3, ref. 2), set the throttle lever on the minimum
rpm, switch off the engine by turning the key on the STOP position (Fig. 1, ref. 1) and lower the deck to
the lowest position.
CLEANING
Clean the outside of the mower after each use.
STORAGE AND PROLONGED PERIODS OF DISUSE
Store the mower in a dry place, away from atmospheric agents, and preferably cover it with a sheet. If
the mower is not going to be used for a long period (over 1 month), disconnect the red battery cable (fig.
23) and follow the instructions given in the engine manual. Also lubricate all of the articulated joints.
Regularly check that the battery voltage does not drop below 12 volts. If it does, recharge the battery.
the machine is to be out of use for more than 30 days, drain the fuel from the engine to prevent sticky
deposits from forming in the fuel intake system or in vital parts of carburettor. To avoid this procedure, it
is possible to save fuel in storage up to 12 months by using an appropriate fuel stabilizer. Add the such
additive to the fuel in the tank or in the fuel container. Run the engine for a while to let the stabilizer get
into the fuel system. Caution: if the engine is fed with petrol containing alcohol, drain the fuel tank and
run the engine until there is no fuel left.
TRANSPORTING THE MACHINE
If the machine has to be transported on a lorry or a trailer, fasten it to the vehicle using ropes or cables.
