Training
Preliminary operations
1) Read the instructions carefully. Become familiar with the controls and the proper use
of the lawnmower. Learn how to stop the engine quickly.
2) Only use the lawnmower for the purpose for which it was designed, namely mowing and
collecting grass. Any other usage may be hazardous and harm persons and/or damage
things. Examples of improper use may include, but are not limited to:
– transporting persons, children or animals on the machine;
– letting oneself be transported by the machine;
– using the machine to tow or push loads;
– using the machine for leaf or debris collection;
– using the machine to trim hedges, or for cutting vegetation other than grass;
– use of the machine by more than one person;
– using the blades on surfaces other than grass.
3 Never allow children or persons unfamiliar with these instructions to use the lawnmower.
Local regulations can restrict the minimum age of the operator.
4) Never use the lawnmower:
– when people, especially children or pets are nearby;
– if the operator has taken medicine or substances that may impair his ability to react and
be attentive.
5) Bear in mind that the operator or user is responsible for accidents or unexpected events
occurring to other people or their property.
1) While mowing, always wear sturdy footwear and long trousers. Do not operate the lawn-
mower when barefoot or wearing open sandals.
2) Thoroughly inspect the entire work area and remove anything that could be thrown by the
machine or damage the cutting unit or engine (stones, branches, iron wire, bones, etc.).
3) WARNING: DANGER! Petrol is highly flammable.
– store the fuel in suitable containers;
– add fuel using a funnel, only outdoors; never smoke while doing this and whenever fuel
is handled;
– add petrol before starting the engine; never add petrol or remove the petrol tank cap
while the engine is running or when it is hot;
– if you have spilt some fuel, do not attempt to start the engine but move the lawnmower
away from the area of spillage to avoid creating any source of ignition until the fuel has
evaporated and fuel vapours have dissipated.
– always put the tank and fuel container caps back on and tighten well;
4) Replace faulty silencers
5) Before use, always inspect generally and in particular to see that the blade, screws and
cutting unit are not worn or damaged. Replace damaged or worn blades and screws to
preserve balance.

Maintenance and storage
Transportation and handling
1) Keep all nuts and screws tight to be sure the equipment is in safe working condition. Rou-
tine maintenance is essential for safety and for maintaining a high performance level.
2) Do not store the lawnmower with fuel in the tank in an area where fuel vapours could
reach an open flame, a spark or a strong heat source.
3) Allow the engine to cool before storing the lawnmower in any enclosure.
4) To reduce fire hazards, keep the engine, silencer, battery compartment and petrol stor-
age area free of grass, leaves, or excessive grease.Never leave containers with cut grass
inside a storage area.
5) Check the stone-guard and grass-catcher frequently for wear or deterioration.
6) If the fuel tank has to be emptied, this should be done outdoors once the engine has
cooled down.
7) Wear work gloves for disassembling and reassembling blades.
8) Keep the blade balanced during sharpening. All work on the blade (disassembly, sharp-
ening, balancing, reassembly and/or replacing) are demanding jobs that require special
skill as well as special tools. For safety reasons, these jobs are best carried out at a spe-
cialized centre.
9) For safety reasons, never use the machine when it has worn or damaged parts. Parts
must be replaced and not repaired. Use original spare parts.Parts that are not of the same
quality can damage the equipment and impair your safety.
1) Whenever the machine is to be handled, lifted, transported or tilted you must:
– wear sturdy work gloves;
– grasp the machine at the points that offer a safe grip, taking account of the weight and
its distribution;
– use an appropriate number of people for the weight of the machine and the character-
istics of the vehicle or the place where it must be placed or collected.
2) During transport, fasten the machine securely with cables or chains.

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 blade efficiency 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.
The appearance of the lawn will improve if you alternate cutting in both directions at the same
height.

Routine maintenance
IMPORTANT – Routine and accurate maintenance is essential in maintaining original
machine safety and performance levels.
Store the lawnmower in a dry place.
1) Wear sturdy work gloves before cleaning, maintaining or adjusting the machine.
2) Accurately wash the machine with water after each mowing, remove grass debris and
mud accumulated under the chassis to prevent it from drying and causing problems the
next time the lawnmower is used.
3) Paint on internal chassis parts may come off over time due to the abrasive action of cut
grass; if this happens, promptly touch-up paint with rust-proof paint to prevent rusting that
could corrode the metal.
4) If accessing the lower part is necessary, only tilt the machine on the side indicated in the
engine manual, following the relevant instructions.
5) Do not drip petrol onto the plastic parts of the engine or the machine to prevent damaging
them and remove all traces of spilt petrol immediately.The warranty does not cover dam-
age to plastic parts caused by petrol.
[1] Blade disassembly and reassembly
Each adjustment made to the blade is best if done at a specialised Centre that has the
most appropriate tools.
Only blades with the following code must be used on this machine:
81004346/3
Blades must always be marked . Given product evolution, the above mentioned blades may
be replaced in time by others, with similar interchangeable and operating safety features.
Reassemble the blade (2) with the code and markings facing the ground, following the steps
indicated in the illustration.
Tighten the central screw (1) using a torque wrench set to 35-40 Nm.
[2] Drive adjustment (Only for Mod. MPRM46SP)
On power-driven models, the proper belt tension is obtained by adjusting the nut (1) to get
the indicated measurement (6 mm).
