MAINTENANCE

Engine

Clean the cylinder fins with compressed air or a brush
periodically (Fig. 66). Dangerous overheating of engine may occur
due to impurities on the cylinder.
WARNING: Never run the machine without all the
parts, including the starting housing, securely in
place.
Because parts can fracture and pose a danger of
thrown objects, leave repairs to the flywheel and
65
clutch to trained Servicing Dealers.

Spark Plug

This engine uses a NGK CMR7A with .02" (0.5 mm) electrode gap
(Fig. 67). Use an exact replacement and replace every six
months or more frequently, if necessary.
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 fire. A loose connection
between spark plug terminal and ignition wire
66
connector in the boot may create arcing that could
ignite combustible fumes and cause a fire.
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.

Muffler

67
WARNING! – This muffler is fitted 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! – Mufflers fitted 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 fire!
CAUTION! – If the catalytic converter is damaged it
68
should be replaced. If the muffler is frequently
blocked, this can be a sign that the performance of
the catalytic converter is impaired.

Spark Arresting Muffler

The brush cutter is provided with a Spark Arrester System
p.n. 61280087 (Fig. 68) complying with the requirements of SAE
J335 standard; you can check the p.n. of the Spark Arrester
System on the muffler itself.
