Operating Instructions

During operation
Check chain tension frequently!
A new chain has to be tensioned more
often than one that has been in use for
some time.
Cold chain:
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 necessary –
see chapter "Tensioning the Saw Chain".
Chain at operating temperature:
The chain stretches and begins to sag.
The drive links on the underside of the
bar must not come out of the bar groove
– the chain may otherwise jump off the
bar.
Retension the chain – see chapter
"Tensioning the Saw Chain".
Always slacken off the chain again
after finishing work. The chain
contracts as it cools down. If it is not
slackened off, it may damage the
gear shaft and bearings.
