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).
