Evaluate the various conditions and be careful in the presence of damp ground and wet grass because
this could cause the mower to slide. When going downhill, start off at a slow speed and avoid driving
over dry or cut grass because the wheels could lose their grip.
Do not run any risks, check the ground carefully and if you do not feel safe, avoid strong slopes and do
not exceed the speed-limits, which are imposed by your country laws and written also in this manual
(max. 17° or 30%).
CUTTING DECK
Mulching system (lever straight up fig. 9). This system is designed to cut and chop grass 10/15 cm tall.
This operation is best done with dry grass as the turbulence inside the deck mulches it better. It is
advisable not to stop the machine after cutting but to continue over the mown lawn for a few minutes to
discharge the grass from the inside of the deck.
Inspect the blades regularly and sharpen or replace them if necessary.
In some parts of Europe, 2 passes are made when using the mulching method; 1/3 of the height of the
grass is cut in the first pass and the other 2/3 in the second. Please evaluate which method best suits
your needs and your type of grass.
Should the grass be taller than 15 cm please mow using the cutting deck in the rear discharge method (fig. 8).
SAFETY DEVICE TRIGGERING
Always remember that the engine stops each time when:
- the operator gets up from the seat, if the parking brake has not been engaged before.
In addition, the engine will not start if:
- the par brake is not engaged;
- if there is no one seated on the driving seat, unless the parking brake has been applied and the blades
have been disengaged;
- the feed levers are not in the stop position;
Attention! When the parking brake is applied, it is possible to leave the driving seat with the engine on.
This operation automatically excludes also the PTO running.
Moreover, the PTO does not work when the platform is raised for the control of the cutting deck.
MAINTENANCE AND LUBRICATION
CAUTION!
Stop the engine and remove the ignition key before carrying out any cleaning, maintenance or repairs.
Always wear suitable working clothes and safety gloves.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment!
Proper maintenance and correct lubrication help to keep the mower perfectly working.
ENGINE
For the lubrication intervals and procedure follow the directions given in the engine manual; it is in any
case indispensable to change the oil and the filter after the first 8 working hours and then every
100 hours. For the petrol engine use SAE 30 oil, 1.7 litres. When you change the engine oil, it is
necessary to change also the oil filter (fig. 4, ref. B). To drain the oil out of the engine, open the lid on the
right side of the engine base (fig. 4, ref. C). Pour in the oil through the lid (fig. 4, ref. A).
The first precaution to be taken is that the engine is maintained correctly with a clean air filter and the
engine oil up to the level.
Keep the engine compartment, the muffler area and the collectors clean. Use a vacuum cleaner if possible.
Check the air filter (fig. 7, ref. B) every 8 hours or even more frequently in dusty conditions. In order not
to reduce the air needed to cool the engine, the grid on the upper part of the engine (fig. 7, ref. A) must
always be kept clean.
HYDRAULIC TRANSMISSIONS
Check the level in the reservoir with cold engines (fig. 5, ref. A). If more oil is needed, add engine oil
OSO 20W50 (total quantity: 4.5 litres). Carry out this control periodically.
Caution! Change the oil in the transmissions the first time after 40 hours and then every 200 hours or at
least once a year.
The oil must be changed before the 200 hours if:
- the oil is black;
- the oil has a whitish colour (it is contaminated with water);
- there are black coloured residues (partial oil deterioration).
