Replace the chain
It is time to replace the chain when the
longest portion of the cutting tooth is less
that 4mm or if you find cracks.
Depth gauge.
The height difference between the position of the depth gauge and tip of the tooth
(depth gauge clearance) determines how much the cutting tooth will cut. It works much
like a plane. When the plane is set up with minimal cutting blades, the plane takes a very
little amount of wood. The same thing happens with the saw chain if the distance be-
tween the depth gauge clearance lip and the tip of the tooth is too small. It is also not
good of the depth gauge clearance lip has been filed down too much. The cutting tooth
will then cut too deeply into the wood. The cut is more aggressive with high vibrations as
a result. The risk of kickback increases and the chainsaw is exposed to unnecessary
stress.
