When saw is cold

:See “Checking Chain Tension”.

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”.

After finishing work

:Disconnect plug from power supply.

: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 drive shaft and bearings.

:Turn the bar over –

every time you sharpen the chain and every time you replace the chain – this helps avoid one-sided wear, especially at the nose and underside of the bar.

: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.

If groove depth is less than specified:

:Replace the guide bar.

The drive link tangs will otherwise scrape along the bottom of the groove – the cutters and tie straps will not ride on the bar rails.
