Use of unapproved fuels will cause damage to
engine components, which will not be covered
under warranty
.
NOTE
Only use the fuel named in the technical
data table. Do not use other types of fuel. It is
possible to use ecological fuels, such as alkylate
petrol. The composition of this petrol has less of
an impact on people and animals. No negative
effects have been reported in connection to their
use. Nonetheless, there are types of alkylate
petrol on the market for which it is not possible
to provide specific indications on their use.
3.7 OIL
Use always high quality oils, choosing
their viscosity grade according to
the operating temperature.
•
Only use detergent oil with a
quality of no less than SF-SG.
•
Choose the SAE viscosity based
on the technical data table.
•
The use of multigrade oil can lead to greater
consumption in hot weather, accordingly it is
necessary to check the level more frequently.
•
Do not mix oils of different brands
and characteristics.
•
SAE 30 oil, if used below +5°C, could
result in possible engine damage
due to inadequate lubrication.
3.8 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.
•
Always keep the filtering element free of
debris and in perfect working order (par. 5.6).
•
If necessary, replace the filtering
element with an original spare part
Incompatible filtering elements can impair
the efficiency and life of the engine.
•
Never start the engine without mounting
the filtering element properly.
3.9 SPARK PLUG
Not all the spark plugs for endothermic
engines are the same.
•
Use only spark plugs of the recommended
type, with the right heat range.
•
Check the length of the thread,
because - if too long - it will damage
the engine beyond repair.
•
Make sure that the electrodes are clean
and that their gap is correct (par. 5.7)
4. REGULATIONS FOR USE
4.1 BEFORE EACH USE
Before every use, perform the following checking
procedures in order to assure a regular operation.
4.1.1
Oil level check
1.
Place the machine on a flat surface.
2.
Clean around the oil fill cap.
3.
Unscrew the cap(fig. 2.A), clean the end of
the dipstick (fig. 2.B) and slide it back in until
the cap is touching the hole, as shown :
–
if the dipstick is short, place the
cap without fastening it,
–
if the dipstick is long, fasten it again
with a click and then unscrew it,
4.
Remove the cap with the dipstick and
check the oil level that must be between
the «MIN» and «MAX» marks.
5.
If oil is required, add oil of the same kind
up to the «MAX» mark, being careful
not to spill any outside the oil fill
6.
Fully tighten the filler cap (fig. 2.A)
and wipe off any spilled oil.
NOTE
Top up gradually, adding small amounts
of oil, checking the level each time.
Do not top up beyond the «MAX» level;
an excessive level can cause:
•
smoking from the exhaust;
•
soiling of the spark plug or air filter with
subsequent difficulty for ignition.
NOTE
For the required type of oil, observe the
indications provided in the technical data table.
4.1.2
Air filter control
The efficiency of the air filter is essential to correct
engine operation; never start the engine if the filter
element is missing, broken or insufficiently saturated
with oil.
1.
Clean around the filter cover (fig.4.A).
2.
Remove the cover (fig. 4.A) by releasing the
tabs (fig. 4.B);
3
. Check the state of the filtering element (fig. 4.C
or 4.C.1), which must be intact, clean and in
perfect working order; if not, either carry out
maintenance or replace it (see 5.6).
4.
Put the cover back in place (fig. 4.A).
