CLEANING
Clean the deck, the entry ducts, the turbine and the basket. Do not wash the engine compartment with water under
pressure, use compressed air or a vacuum cleaner.
STORAGE AND LACK OF USE FOR LONG 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 lead from the battery 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 Volts and if it does so, recharge it.
For machines with petrol engines use a conserving additive for unleaded petrol.
ACCESSORIES
150 CM SIDE DISCHARGE CUTTING DECK
This is suitable for mowing in parks or gardens which are so large that grass collection is unnecessary.
If the grass is not too high and the engine is not pushed too hard, work in such a way that the cut grass is spread
over the grass still to be cut; in this way the lawnmower will pass several times over the grass already cut, shredding
it finely and dispersing it over the lawn.
Use the 4 pins (fig. 34) to adjust the cutting height.
The grass is discharged through an outlet fitted with a bar to prevent the ejection of objects and this bar must not
be removed under any circumstances. When working near roads be careful not to spray grass onto the
carriageway, keep any persons at a distance of 15/20 metres.
The main features are its cutting quality and robust construction, it can also be fitted with a mulching kit.
Maintenance
1. Every 50 hours grease the blade pin bearings (fig. 35).
2. Check the belt tension every 50 hours and if necessary adjust it (A, fig. 36). The play on the belt must never
exceed 8/10 mm.
3. Blade maintenance:
a) Remove the split pins and side pins (fig. 37).
b) Release the universal joint from the deck by pressing on the button (fig. 38).
c) Lift the deck manually and attach it to the hook on the instrument panel (fig. 39).
d) Sharpen the blades or replace them if they show signs of wear. When lowering the deck again, carry out the
same procedure in reverse order, making sure to reconnect the universal joint.
e) Angle drive oil. Check the level every 40 hours, change it every 200 hours. Use synthetic oil 75 W 90 LSX
(international codes: API GL4 + GL5; API MT1 and PG2; MIL-L-2105D; MIL-PRF-2105E) (B, fig. 36) quantity - 0.15 lt.
Caution! Use an oil syringe for this operation.
110 CM MULCHING DECK (FIG. 40)
This is for cutting and mulching grass 10/12 cm high. 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 for a few minutes over the already cut lawn to
discharge the grass from inside the deck.
It is attached in the same way as the other decks. Check the condition of the blades regularly, sharpen or replace
them if necessary.
Check the oil level in the transmission unit, change the oil every 300 hours, 0.6 lt. (75 W 90 SYNTHETIC).
This deck too has safety screws on the blades which shear off in the event of impact. They must be replaced with
interchangeable screws in mild steel.
In some European areas mulching involves two cuts; a first passage cuts 1/3 of the grass height and a second cutting
removes the remaining 2/3. Gauge which type of cut is most suited to your expectations and the type of grass.
110 CM GRASS SHREDDER (FIG. 41)
Very useful for clearing countryside with tall, wild grass. Allows the cut product to be shredded making collection unnecessary.
It comes equipped as standard with “Y” shaped hoes, also suitable for shredding small pruned branches. It can
be fitted with grass blades to give a cutting quality equal to that of the lawnmower, or converted into a scarifier by
changing the blades holding roller or by simply replacing the hoes with expulsion vanes.
Applied in the same way as the lawnmower, be careful to fit the universal joint onto the grooved shaft.
Check regularly the tension on the belts at the side of the grass shredder and grease the belt supports.
If the grass shredder vibrates, check the hoes.
