Carburettor adjustment
Conditions during adjustment
•
The airfilter should be clean and the cylinder coverfitted
when adjustments are made. Adjusting the carburettor
with a dirty airfilter will give a too lean fuel mixture
the next time the airfilter is cleaned. This can result in
serious damage to the engine.
•
Mount, for this model, approved bar and chain
combination (see Technical data in the Operator's
Manual).
