During Operation
17.1.1
Check chain tension frequently
A new chain has to be retensioned more often
than one that has been in use for some time.
17.1.2
Chain cold
Tension is correct when the chain fits snugly
against the underside of the bar and can still be
pulled along the bar by hand. Retension if neces‐
sary – see "Tensioning the Saw Chain".
17.1.3
Chain at operating temperature
The chain stretches and begins to sag. The drive
links must not come out of the bar groove – the
chain may otherwise jump off the bar. Retension
the chain – see "Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it is not
slackened off, it can damage the gear shaft and
bearings.
17.2
After Finishing Work
► Slacken off the chain if you have retensioned it
at operating temperature during cutting work.
NOTICE
Always slacken off the chain after finishing work.
The chain contracts as it cools down. If it is not
