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.

Long-term storage

NTurn 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.

NRegularly clean the oil inlet hole (1), the oilway (2) and the bar groove (3).

NMeasure the groove depth – with the scale on the filing gauge (special accessory) – in the area used most for cutting.

If groove depth is less than specified:

NReplace 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.
