MAINTENANCE

Starter Unit

WARNING: The coil spring is under tension and
could fly apart causing serious injuries. Never try to
disassembly or modify it.

Engine

Clean the cylinder fins with compressed air or a brush periodically
78
(Fig. 78). Dangerous overheating of engine may occur due to
impurities on the cylinder.
WARNING: Never run the pole pruner without all the
parts, including the drivecase cover and starting
housing, securely in place. Because parts can fracture
and pose a danger of thrown objects, leave repairs to
the flywheel and clutch to trained Servicing Dealers.

Spark Plug

79
This engine uses a NGK CMR7A with .02" (0.5 mm) electrode gap
(Fig. 79). 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
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

WARNING – This muffler incorporates a catalytic
converter, needed in order to ensure the engine
complies with current emissions standards. Never
attempt to modify or remove the catalytic converter: in
doing so, you will be breaking the law.
WARNING – Mufflers with catalytic converters become
very hot during operation, and retain heat for a long
time after the engine has been stopped. This is the
case even with the engine idling. Contact can burn
the skin. Always remember the potential fire risk!
CAUTION – If the catalytic converter is damaged, it
must be replaced. If the catalytic converter frequently
becomes blocked, this could be an indication that the
efficiency of the muffler is limited.
