General information about how to sharpen the
cutters
Do not use a blunt saw chain. If the saw chain is blunt,
you must apply more pressure to push the guide bar
through the wood. If the saw chain is very blunt, there
will be no wood chips but sawdust.
A sharp saw chain eats through the wood and the wood
chips becomes long and thick.
The cutting tooth (A) and the depth gauge (B) together
makes the cutting part of the saw chain, the cutter. The
difference in height between the two gives the cutting
depth (depth gauge setting).
When you sharpen the cutter, think about the following:
• Filing angle.
• Cutting angle.
• File position.
• Round file diameter.
It is not easy to sharpen a saw chain correctly without
the correct equipment. Use Husqvarna file gauge. This
