EMISSIONS COMPLIANCE
This engine, including the emissions control
system, must be operated, used and maintained
in accordance with the instructions provided
in the user's manual in order to maintain
the emissions performance within the legal
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
engine or of the non-road mobile machinery
could result in possible malfunctions of the
emissions control system to a point where 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:
- Forcing or breaking the devices for metering
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.
WARNING! – Tampering with this engine
makes the EU emissions certification no more
valid .
The level of CO2 of this engine can be found in
the Emak's website (www.myemak.com) under
section "The Outdoor Power Equipment World".
WARNING! – Always wear protective
gloves during maintenance operations. Do not
carry out maintenance with the engine hot.
Never carry out maintenance operations with
the engine running.
- Non-correct maintenance and removal of
safety devices could cause serious injuries.
- Do not use fuel mix ture 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.
