During operation
Check chain tension frequently
A new chain has to be retensioned more often than one that has been in use for some time.
Chain cold:
Tension is correct when chain fits snugly against the underside of the bar and can still be pulled along the bar by hand.
Retension if necessary – see “Tensioning the Saw Chain”.
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”!
Always slacken off the chain after finishing work. The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings.
After long period of
Allow engine to run for a short while at idle speed so that engine heat can be dissipated by flow of cooling air. This protects
After finishing work
:Slacken off the chain if you have retensioned it at operating temperature during cutting work.
The chain contracts as it cools down. If it is not slackened off, it could damage the crankshaft and bearings.
Storing your saw for a short period: Wait for engine to cool down. To avoid condensation, fill the fuel tank and keep the machine in a dry place, well away from sources of ignition, until you need it again.

:Regularly clean the oil inlet hole (1), the oilway (2) and the bar groove (3).
:Measure groove depth –
with scale on filing gauge* – in area used most for cutting.
