CAUTION! – If the catalytic
converter is damaged it should
be replaced. If the muffl er is
frequently blocked, this can be a
sign that the performance of the
catalytic converter is impaired.
Spark Arresting Muffl er (Fig. 25)
WARNING: A faulty or altered
spark arrester system screen can
create a fi re hazard.
Through normal use the screen can become
dirty and should be inspected weekly and
cleaned as required.
To clean:
• Allow the muffl er to cool.
• Remove the muffl er cover (A).
• Remove the six (6) defl ector screws (B).
• Remove the defl ector (C), the gasket (D)
and spark arrester (E).
• Clean and inspect the spark arrester
screen. If the spark arrester screen is
damaged, faulty or deteriorated, replace
the screen.
• Reassemble components in reversed order
of removal and torque the screw to 40 in/
lbs (4.5 Nm).
WARNING: If the spark arrester
screen is damaged, faulty or
deteriorated, replace the screen
or entire muffl er assembly.
The Spark Arrester System needs a periodic
and accurate maintenance and cleaning, in
particular:
- check periodically the spark arrester
WARNING: Never test the
ignition system with ignition wire
connector removed from spark
plug or with unseated spark plug,
since uncontained sparking may
cause a fi re. A loose connection
between spark plug terminal and
ignition wire connector in the
boot may create arcing that could
ignite combustible fumes and
cause a fi re.
Use only resistor type spark plugs of the
approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air fi lter;
- unfavourable running conditions, e.g.
operating at part load;
may result in rapid deterioration of the spark
plug.
Muffl er
WARNING! – This muffl er is fi tted
with a catalytic converter needed
for the engine to be in compliance
with the emissions requirements.
Never modify or remove the
catalytic converter: failure to do
so is a violation of law.
WARNING! – Muffl ers fi tted with
catalytic converters get very hot
during use and remain so for
some time after stopping. This
also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fi re!
