difficult cold starting.
– When operating at very high temperatures, a
warm start could prove difficult due to evapo-
ration of fuel in the float chamber of the car-
burettor or in the pump.
– In any case, the right kind of oil must be used,
according to the operating temperatures.
b) Altitude:
– The higher the altitude (above sea level), the
lower the max power developed by an
endothermic engine.
– Therefore, at the highest altitudes the load on
the lawnmower should be reduced avoiding,
for example, to cut tall or wet grass.

FUEL (ETHANOL E 85 + 1% ADDITIVE
MTR-LIFE
®
)
A good quality fuel is essential for the engine to
function efficiently.
Ethanol E85 available on the market MUST
always contain the specific additive MTR-LIFE
(Available from your Reseller) in the proportion of
1 cl of additive for each litre of Ethanol E85.
IMPORTANT
The use of Ethanol E85
without the additive will damage the engine
irreparably and cause the annulment of any
form of warranty.
• Preparation and storage of the fuel with
additive
– Place about half the amount Ethanol E85 in a
homologated tank.
– Add the additive MTR-LIFE
of 1 cl of additive for each litre of Ethanol E85.
– Add the rest of the Ethanol E85.
– Close the cap and shake well.
IMPORTANT
The fuel is subject to ageing.
Do not prepare excessive amounts of the fuel
mixture to avoid deposits from forming.
IMPORTANT
Keep the containers with
Ethanol E85 and fuel with additive separate and
easily identifiable to avoid the mistake of using
one in place of the other.
IMPORTANT
Clean the containers period-
ically to remove any deposits.

OIL
Use always high quality oils, choosing their vis-
cosity grade according to the operating temper-
ature.
a) Use only detergent oil classified SF-SG.
b) Choose the SAE viscosity grade of oil from
this chart:
– from 5 to 35 °C
– from -15 to + 5 °C
– from -25 to + 35 °C = Synthetic oils 5W-30
c) The use of multi-viscosity oils in hot temper-
atures will result in higher than normal oil con-
sumption; therefore, check oil level more fre-
quently.
e) Do not mix oils of different brands and fea-
tures.
d) SAE 30 oil, if used below 5°C, could result in
possible engine damage due to inadequate
lubrication.
f) Oil should be at "MAX" mark (see 5.1.1): do
not overfill. Overfilling with oil may cause:
– Smoking;
– Spark plug or air filter fouling, which will
®
cause hard starting.
4.4
AIR FILTER
The air filter must always be in perfect working
order, to prevent grass cuttings and dust from
getting sucked into the engine, reducing the effi-
ciency and life of the machine.
a) Always keep the filtering element free of
grass cuttings and in perfect working order
(see 6.5).
b) If necessary, replace the filtering element with
an original spare part. Incompatible filtering
elements can impair the efficiency and life of
the engine.
c) Never start the engine without mounting the
filtering element properly.
4.5
SPARK PLUG
Not all the spark plugs for endothermic engines
are the same!
a) Use only spark plugs of the recommended
type, with the right heat range.
b) Check the length of the thread, because – if
too long – it will damage the engine beyond
repair.
c) Make sure that the electrodes are clean and
their gap is correct (see 6.6).
