EN - 5
Raise the rear discharge guard and fasten the grass catch -
er (1 or 2) correctly in place, according to the different pro -
cedures foreseen for each type used.
3.2 Engine ignition
During ignition, follow the instructions in the engine ma -
nual.
3.2a
• Manual ignition models (“I - “II”)
Pull the cutting means brake lever (1) against the handle
and firmly tug the knob on the ignition cable (2).
• Electric key ignition models
Pull the cutting means brake lever (1) against the handle
and turn the ignition key (3).
3.2b
• Electric push-button ignition models (“III - “IV”)
– Insert the supplied battery in the relative engine com -
partment (4); (follow the instructions provided in the en -
gine manual).
– Insert the key as far as possible (if fitted) (5).
– Pull the engine cutting means brake lever towards the
handle (1).
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).
3.3 Mowing the lawn
The appearance of the lawn will improve if you alternate
cutting in both directions at the same height.
When the grass catcher is too full, grass collection is no
longer efficient and the sound of the lawnmower changes.
To remove and empty the grass catcher,
– stop the engine and wait for the cutting means to stop;
– lift the rear discharge guard, grasp the handle and re -
move the grass catcher keeping it in an erect position.
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:
– cutting too low tears and uproots the grass, giving it a
“spotted” appearance;
– in the summer, cutting must be higher to prevent the
ground from drying;
– do not cut wet grass; this could reduce cutting means ef -
ficiency due to sticky grass and tear the lawn.
– for particularly high grass, initially mow at the maximum
height allowed by the machine then mow again after two
or three days.
3.4 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
Remove the ignition key (3).
• Electric push-button ignition models
Press 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) Wear strong protective gloves before cleaning, main -
taining or adjusting the machine.
2) Accurately 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) If 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.
4) 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.
5) On models with AVS: If the handle vibrates unusually,
check the anti-vibration sleeves and contact your Dealer
to replace them if damaged or worn.
6) To 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.
4.2 Drive adjustment
On power-driven models, the drive belt tension is obtained
by adjusting the nut (1) until the indicated measurement (6
mm) is obtained.
4.3 Battery recharging (where applicable)
