– l ift 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.

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

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 35-40 Nm.
On power-driven models, the drive belt tension is obtained
by adjusting the nut (1) until the indicated measurement (6
mm) is obtained.
• Electric key ignition models
To recharge a flat battery, connect it to the battery charg-
er (1) following the instructions in the battery maintenance
manual.
Do not connect the battery charger directly to the engine
terminal. It is not possible to ignite the engine using the
battery charger as a power source, as it may get damaged.
If you do not use the lawnmower for a long period of time,
disconnect the battery from the engine wiring, making sure
the charge level is good.
• Electric push-button ignition models
Follow all the instructions provided in the engine Instruc-
tion Manual.

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.
erly over time, it is highly recommended to
change the engine oil regularly, following the tim-
ing indicated in the engine's Instruction Manual.
The oil can be discharged at a specialised ser-
vicing centre, or by using a syringe to suc-
tion the oil out through the filler spout, bearing in
mind you may need to repeat the operation sever-
al times in order to completely empty the tank.
Remember to top-up with oil before using the ma-
chine again.
