is not slackened off, it can damage the
crankshaft and bearings.
After a long period of full-throttle
operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the

retensioned it at operating
temperature during work.
NOTICE
Always slacken off the chain again after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the crankshaft and
bearings.
Short-term storage
Wait for engine to cool down. Keep the
machine with a full tank of fuel in a dry
place, well away from sources of
ignition, until you need it again.
