NOTE Keep pulling the engine / cutting means brake or
the engine will stop.
– Press and hold the starter button until the engine
switches on (6).
3.2 Mowing the lawn
The appearance of the lawn will improve if you alternate
cutting in both directions at the same height.
A machine that is equipped with a MULCHING system cuts
the grass, chops it then distributes it over the lawn. It is not
necessary to collect the cut grass.
For best MULCHING results, proceed as follows:
1. N ever cut the grass too short. Only cut the grass by 1/3
of its height.
2. K eep the body shell perfectly clean (underneath).
3. A lways use well sharpened cutting means.
4. A void mowing wet grass. It accumulates more easily
under the body shell and the mowing performance de-
creases considerably.
Lawn care recommendations
Each type of grass has different characteristics and may
thus require different ways of caring for the lawn; always
read the instructions on seed boxes for mowing height for
the growing conditions in the work area.
Keep in mind that most grass is made up of a stem and one
or more leaves. If leaves are fully cut, the lawn is damaged
and growth is more difficult.
The following indications generally apply:
– c utting too low tears and uproots the grass, giving it a
"spotted" appearance;
– i n the summer, cutting must be higher to prevent the
ground from drying;
– d o not cut wet grass; this could reduce cutting means ef-
ficiency due to sticky grass and tear the lawn.
– f or particularly high grass, initially mow at the maximum
height allowed by the machine then mow again after two
or three days.
3.3 When work is finished
When work has been completed, release the brake lever (1)
and disconnect the spark plug cap (2).
• Electric key ignition models
R emove the ignition key (3).
• Electric push-button ignition models
P ress the tab (5) and remove the consent key (4).
WAIT UNTIL THE CUTTING MEANS STOPS before pro-
ceeding any further.
4. ROUTINE MAINTENANCE
Store the lawnmower in a dry place.
IMPORTANT Routine and accurate maintenance is es-
sential in maintaining original machine safety and perfor-
mance levels.
Adjustments or maintenance operations must only be per-
formed with the engine switched off and the spark plug ca-
ble disconnected.
1) W ear strong protective gloves before cleaning, main-
taining or adjusting the machine.
2) A ccurately wash the machine with water after cutting;
remove grass debris and mud accumulated in the chas-
sis to prevent it from drying and causing problems the
next time the lawnmower is used.
3) On models with painted chassis: paint on internal
chassis parts may start to flake over time due to the
abrasive action of cut grass; if this happens, promptly
touch-up with rust-proof paint to prevent rusting that
could corrode the metal.
4) I f accessing the lower part is necessary, only tilt the ma-
chine on the side indicated in the engine manual, fol-
lowing the relevant instructions, making sure that the
machine is perfectly stable before performing any in-
terventions.
5) Do not drip petrol onto the plastic parts of the engine or
the machine to prevent damaging them and remove all
traces of spilled petrol immediately. The warranty does
not cover damage to plastic parts caused by petrol.
6) T o ensure that the machine will function properly over
time, it is highly recommended to change the engine oil
regularly, following the timing indicated in the engine's
Instruction Manual.
The oil can be discharged at a specialised servic-
ing centre, or by using a syringe to suction the oil out
through the filler spout, bearing in mind you may need
to repeat the operation several times in order to com-
pletely empty the tank.
Remember to top-up with oil before using the ma-
chine again.
4.1 Cutting means maintenance
It is best if all interventions on the cutting means are done
at a specialised Centre that has the most appropriate tools
and equipment.
Only cutting means bearing the code indicated in the table
on page ii must be used on this machine.
Given product evolution, the above mentioned cutting
means may be replaced in time with others having similar
interchangeable and operating safety features.
Reassemble the cutting means (2) with the code facing
the ground, following the steps indicated in the illustration.
Tighten the central screws (1) using a torque wrench set to
the values specified for each type of cutting means.
4.2 Drive adjustment
On power-driven models, remove the guard (1) once or
twice a year by unscrewing the screws (2) and releasing
the fittings (3) (if provided). Then clean carefully using a
brush or compressed air, removing the grass and dirt from
the area around the transmission and belt. Always reas-
semble the guard (1).
1. P ush the lawnmower back and forth with the transmis-
sion disengaged.
2. S et the clutch control to position «
lawnmower until the front wheels engage.
3. In this position, the spring (11) should have an extension
of 6 mm as opposed to the position when unloaded, to
guarantee sufficient transmission locking force.
4. I f the spring is not sufficiently extended, adjust the wire
nipple (13) near the bar.
5. S tart by loosening the locknut (12) and then adjust the
nipple (13).
6. S et the clutch control to the « » position and check that
the transmission is disengaged by pushing the lawn-
mower back and forth.
