ge guard (4).
– Release the side discharge chute (8).
To remove the chute flap:

3.2 Engine ignition
During ignition, follow the instructions in the engine ma-
nual.
3.2a
• Manual ignition models ("I - "II" - "III")
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 ("IV - "V")
– 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,
– s top 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.
• For mulching or rear grass discharge: always avoid
removing a large quantity of grass. Never cut more
than one third of the total grass height per single pass!
Regulate the forward speed according to the lawn condi-
tions and the amount of grass removed.
• For side discharge (if applicable): it is best to mow in
a pattern where cut grass is not discharged on the grass
still to be cut.
• For a grass catcher with contents indicator device
(if applicable): while working with the cutting means
running, the indicator remains raised for as long as the
grass catcher is able to hold cut grass; when it lowers, it
means that the grass catcher is full and must be emptied.
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.
3.4 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) 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) P aint on internal chassis parts may start to flake over
time due to the abrasive action of cut grass; if this hap-
pens, 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. On side discharge models, remove the di-
scharge chute (if installed – see 3.1.d).
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) ì U se the specific attachment for the water hose to clean
the internal parts of the chassis (if provided). To per-
form the cleaning, adjust the cutting height to the low-
est setting, then start the engine and engage the cutting
means, standing behind the lawnmower handle.
7) 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 en-
gine's Instruction Manual. The oil can be discharged
at a specialised servicing centre, or by using a syringe
to suction the oil out through the filler spout, bear-
