tensioning device must lock

retaining nut.

Tensioning the Saw Chain

1. For tightening
chain, turn the retaining nut
clockwise.
2. For loosening the tension,
turn the
counter clockwise.
Hints:

Only use sharp chains. Dull chains can easily get jammed. While
working with new chains, regularly check the chain tension because
new chains can lengthen considerably upon initial operation.

The service life of a saw chain mainly depends on sufficient
lubrication and correct tensioning.

During operation, the saw chain heats up, and tensioning may be
necessary. Slacken the chain after use so it will not be too tight
after cooling down.

Do not tension an overheated chain. After cooling down, the chain
may shorten and become over tensioned. Before tensioning the
saw chain, wait until it has cooled down.
