CMR7H
MAINTENANCE

Starter Unit

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

Engine

Clean the cylinder fins with compressed air or a brush periodically.
Dangerous overheating of engine may occur due to impurities on the
52
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 clutch to
trained Servicing Dealers.

Spark Plug

This engine uses a NGK CMR7H with .02" (0.5 mm) electrode gap
(Fig. 52). 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 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
should be replaced. If the muffler is frequently blocked,
this can be a sign that the performance of the catalytic
converter is impaired.
