Notes on tensioning the chain:

The chain must be properly tensioned to ensure safe operation. When the saw chain can be raised by

around 2 mm in the middle of the cutter bar, you know that the chain tension is ideal. During cutting, the

temperature of the chain rises and its length changes. It is important therefore to check the chain tension at

least every 10 minutes and to adjust it again as required. This applies in particular to new saw chains. When

you have fi nished working, slacken the chain again as it will shorten when it cools down. This will help to

prevent damage tothe chain.
