ring to other people or their property.
B) PREPARATION
1) Do not wear loose-fitting clothing, dangling
drawstrings, jewels or items that could
become caught; tie up long hair and keep at
safe distance while starting the lawnmower.
2) Turn engine OFF and let it cool before
removing gas cap.
3) WARNING: DANGER! Fuel is highly flam-
mable:
–store the fuel in special containers;
–refuel only outdoors by using a funnel;
never smoke while refueling and/or han-
dling fuel;

–add fuel before starting the engine. Never
remove the cap of the fuel tank or add fuel
while the engine is running or when the
engine is hot;
–if you have split some fuel, do not attempt
to start the engine but move the machine
away from the area of spillage and avoid
creating any source of ignition until the fuel
has evaporated and fuel vapours have dis-
sipated.
–always put the tank and fuel container caps
back on and tighten well.
4) Replace faulty silencers and the guard, if
damaged.
C) OPERATION
1) Do not operate the engine in a confined
space where dangerous carbon monoxide
fumes can collect.
2) Do not use starting fluids or similar prod-
ucts.
3) Do not change the engine governor set-
tings or overspeed the engine.
4) Do not tilt the machine onto its side to pre-
vent fuel leaks from the fuel tank cap.
5) Do not touch the cylinder fins and/or the
silencer guard until the engine has cooled
down.
6) Stop the engine and disconnect the spark
plug cable before checking, cleaning or serv-
icing the machine or the engine.
7) Do not crank the engine with spark plug
removed.
8) Transport the machine with empty tank.
D) MAINTENANCE AND STORAGE
1) A routine maintenance is essential for safe-
ty and for keeping a high performance level.
2) Do not store the machine with fuel in the
tank in an area where the fuel vapours could
reach an open flame, a spark or a strong heat
source.
3) Allow the engine to cool before storing in
any enclosure.
4) To reduce the fire hazard, keep the engine,
the silencer and the fuel storage area free of
grass, leaves, or excessive grease.
5) If the fuel tank has to be drained, this
should be done outdoors once the engine has
cooled down.
6)On safety ground, never use the engine
with either worn or damaged parts. Parts are
to be replaced and not repaired. Use genuine
spare parts. Parts that are not of the same
quality can damage the engine and impair
your safety.

ACCELERATOR CONTROL
The throttle trigger (generally a lever), fitted to
the machine, is connected to the engine by a
cable.
Consult the machine’s Instructions Manual to
identify the throttle trigger and its positions, usu-
ally marked by symbols, corresponding to:
CHOKE = to be used for starting from
cold.
FAST = corresponds to maximum revs;
to be used when working.
SLOW = corresponds to minimum revs.

The engine performance, reliability and life are
influenced by many factors, some external and
some strictly associated with the quality of the
products used and with the scheduled mainte-
nance.
The following information allow a better under-
standing and use of your engine.
ENVIRONMENTAL CONDITIONS
The operation of a four-stroke endothermic
engine is affected by:
a) Temperature:
–Working in low temperatures could lead to a
difficult cold starting.
–Working in very high temperatures could lead
to a difficult hot starting due to the evapora-
tion of the fuel either in the carburetor float
chamber 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.
–When there is a considerable increase in alti-
tude, the load on the machine should be
reduced and particularly heavy work avoided.
FUEL
A good quality fuel is the major issue for the
engine reliability of operation.
a) Use unleaded gasoline, with a minimum of 90
octane.
b) Use clean, fresh fuel; purchase fuel in quanti-
ty that can be used within 30 days, to prevent
gum from forming inside the container or the
tank.
c) Do not use fuel which contains Methanol.
d) Do not add neither oil nor any kind of fuel
additive.
OIL
Use always high quality oils, choosing their vis-
cosity grade according to the operating temper-
ature.
4.3
4.2
4.1
4. WHAT YOU NEED TO KNOW a) Use only detergent oil classified SF-SG.
b) Choose the SAE viscosity grade of oil from
this chart:
– from 5 to 35 °C = SAE 30
– from -15 to + 5 °C = 5W-30 or 10W-30
(Multi-viscosity)
– from -25 to + 35 °C = Synthetic oils 5W-30
or 10W-30
(Multi-viscosity)
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.
d) Do not mix oils of different brands and fea-
tures.
e) SAE 30 oil, if used below 5°C, could result in
possible engine damage due to inadequate
lubrication.
f)
–Smoking;
–Spark plug or air filter fouling, which will
cause hard starting.
AIR FILTER
The air filter must always be in perfect working
order, to prevent debris and dust from getting
sucked into the engine, reducing the efficiency
and life of the machine.
a) Always keep the filtering element free of
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.
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
