If the electrical problems still persist even after having changed the fuses, contact the Authorised Service
Centre. Never attempt to carry out complex repairs without having the necessary means and technical
knowledge available.
HOW THE MAIN ELECTRICAL SYSTEM DEVICES WORK
- A safety micro switch detects if the foot rest platform is in the working position (fig. 20, ref. B).
Otherwise the cutting deck does not work.
- On the feed levers there are two micro switches that detect the position and the engagement of the
parking brake.
- Under the driving seat there is a micro switch that senses the driver's presence on the machine.
- The electrovalve that controls the machine's stabilizing mechanism on slopes (fig. 6, ref. C) is situated
behind the right hydrostatic transmission. Under normal working conditions the electrovalve is
illuminated by a red LED. When the machine's stabilizing device intervenes, the red LED goes out.
- On the electromagnetic clutch cable there is a diode that prevents returns of current.
- The control unit (fig. 3) signals when the main devices of the machine are engaged or disengaged.
Furthermore, it stores and indicates the machine's working hours.
AIR FILTER
Check and clean the air filter (fig. 4, ref. D) every 8 hours or more frequently if you work in dry and dusty
conditions. For the substitution and the exact maintenance intervals, please follow the instructions and
warnings given in the engine manual.
PETROL FILTER
The petrol filter (fig. 7, ref. B) prevents possible impurities in the petrol from getting in contact with engine
parts. Clean the petrol filter every 200 hours, and also wash the inside with clean petrol. For the cleaning
and the exact maintenance intervals, please follow the instructions and warnings in the engine manual.
CLEANING
Wash the cutting deck with a high-pressure water jet machine but do not direct the water jet to the
electrical components. Never clean the electric compartment with the high-pressure water jet machine,
use compressed air or a vacuum cleaner instead. Keep the hydrostatic transmissions area especially
clean in order to guarantee an efficient cooling. Always keep the aspiration grid on the engine and the air
filter clean.
TOWING HOOK
The towing hook is located in the rear part of the machine. You can tow compaction rollers and trailers
up to max. 120 kg weight on a 10% slope.
TOWING THE MACHINE WITH A CUT OFF ENGINE
Attention! To be able to move the machine when the engine is cut off you have to act on the hydrostatic
transmissions by-pass levers (fig. 5, ref.C); pay attention because doing so the efficiency of the self-
sustaining braking system is cancelled.
Tow the machine at a very low speed (less than 3.2 km/h) and only over short distances, no
longer than 100 metres, to avoid seizing of the hydraulic pump or of the engines inside the
hydrostatic unit.
STORAGE AND LACK OF USE FOR LONG PERIODS
Store the machine in a dry environment, sheltered from bad weather and, if possible, covered up.
If the mower will not be used for a long period (more than one month), disconnect the battery red cable
and follow the directions given in the engine manual; in addition grease all the joints.
Check regularly that the battery voltage has not dropped below 12.5 Volts and if necessary, recharge it.
WARNINGS FOR TRANSPORT
In case it should be necessary to lift the machine, check the machine's weight on the identification plate
and use only suitable equipment (ramps, cranes, etc.).
If the machine is carried with a lorry or with a towed trailer, set the cutting deck at a low position, apply
the parking brake and tie the machine up to the means of transport using ropes, cables, or chains.
