View no. 1 (fig. 53): the display shows the engine r.p.m., the clock, the machine's working hours and the scheduled
maintenance intervals. As default setting, the display shows the machine's working hours. The time left to the next
maintenance will be displayed for about 10 minutes, then it will go back to the hourmeter. The display will then show
"0" if the time for the scheduled maintenance has been reached and/or overcome (fig. 56). This means it is now
time to carry out the prescribed maintenance. If the display shows an error message (fig. 57), it is highly
recommended to check the corresponding micro-switch.
ELECTROVALVE UNIT
The activation of the turbine, the clutch and the radiator fan is controlled by a unit of electro-valves located on the
machine's left side under the protection housing (fig. 49). There are three little plugs to check the pressure. The
pressure of both the hydraulic steering and the radiator fan is measured in the plug no. 1 (fig. 49, n. 1) This
procedure must be carried out by an authorized dealer only. To check the turbine pressure connect a pressure
gauge on the plug (fig. 50, n. 2) – this procedure must be carried out once the turbine has been blocked, the max.
pressure is 260 BAR. To check the PTO hydraulic clutch pressure, connect a pressure gauge on the plug (fig. 50, n.
3) with the engine running - max. pressure 9 BAR. To adjust the pressure of the turbine use the screw and its nut
(fig. 52, A). To adjust the pressure of the hydraulic steering use the screw and its nut (fig. 52, C).
procedures must be carried out by an authorized dealer only. Always hold the cap well-tightened on the plugs
to prevent impurities from getting inside them. Do not wash the unit of the electro-valves with the high-pressure
water, clean it with compressed air or use a vacuum cleaner.
CLEANING
Clean the deck, the entry ducts, the loading turbine and the grass catcher. Do not wash the engine compartment
with high pressure water, use compressed air or a vacuum cleaner.
TOWING HOOK
The tow hook is located in the rear part of the machine (fig. 33). You can tow compaction rollers and trailers up to
max. 400 kg weight on level ground. It is forbidden to tow trailers on public road.
TOWING THE MACHINE WITH THE CUT OFF ENGINE
On the forward pump there are three hydraulic plugs to check the pressure (fig. 26). In A and B pressure can reach
max. 300 BAR.n In C pressure can reach max. 25 BAR (overfeeding pump). In the points no. 1 and 2 on the pump
there are two screws. To move the machine loosen the counter-nuts and fully unscrew the two screws. Pay
attention because doing so the efficiency of the self-braking device is cancelled. Tow the machine at very low speed
and only on small distances
LIFTING HOOKS AND TRANSPORT
The lifting hooks (fig. 34) enable the machine and its cutting deck to be perfectly balanced if it must be lifted up with
a crane. Check the machine's weight on the serial number 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 it up to the means of transport using ropes, cables, or chains.
STORAGE AND LONG IDLE PERIODS
Store the machine in a dry environment, sheltered from the elements and, if possible, covered up. If the mower will
not be used for a long period (more than one month), disconnect the red battery lead 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.
