- Non-correct maintenance and removal of

safety devices could cause serious injuries.

- Do not use fuel mixture for cleaning

operations.

- Do not attempt to carry out operations

or repairs that are not part of the normal
maintenance. See the authorised dealer.

AIR FILTER

In the event of a significant decrease in engine

power, open the cover (A, Fig.11) and check the

air filter (B). To clean the air filter, refer to Fig.11

and proceed as follows:

· Undo the two screws (C) to remove the cover

and access the filter.

· Replace it if clogged or damaged. Before

fitting the new filter, remove coarse dirt from

inside the cover and from the area around

the filter.

· Refit the filter (B) and close the cover (A),

tightening the two screws (C).

CAUTION – Using the blower without the

air filter or with a very dirty air filter can damage
the engine and will invalidate the warranty.

FUEL FILTER (Fig. 12)
We recommend changing the fuel filter in the
fuel tank at least once a year. This operation must
be carried out by an Authorized Service Centre:

· Empty the fuel tank.
· Extract the filter and disconnect it from the

fuel hose.

· Fit a new filter in the fuel hose.
· Re-insert the filter in the fuel tank.

CAUTION – Failure to replace the fuel filter

when it is dirty will result in impaired operation

of the engine.

ENGINE

Clean cylinder fins with a brush or compressed

air periodically. Dangerous overheating of engine

may occur due to impurities on the cylinder.

SPARK PLUG

Clean spark plug and check electrode distance

periodically (Fig.23). Use NGK CMR7A or of other

brand with the same thermal grade.

EMISSIONS COMPLIANCE
This engine, including the emissions control
system, must be operated, used and maintained
in accordance with the instructions provided

requirements applicable to non-road mobile
machinery.

No deliberate tampering with or misuse of the
engine emissions control system has to take
place.

Incorrect operation, use or maintenance of the

legal requirements applicable are not respected;
in such case a prompt action must be taken in
order to rectify the system’s malfunctions and
restore the applicable requirements.

Examples, not exhaustive, of incorrect operation,
use or maintenance are:

the fuel;

- Use of fuel and/or engine oil not fulfilling the

characteristics shown in the chapter STARTER
/ FUELING;

- Use of not original spare parts, for example

spark plug, etc. ;

- Missing or improper maintenance of the

exhaust system, including incorrect timing of
maintenance for muffler, spark plug, air filter, etc.
