General inf
ormation on sharpening
cutting teeth
•
Never use a blunt chain. When the chain is blunt you
have to exert more pressure to force the bar through
the wood and the cuttings will be very small. If the
chain is very blunt it will not produce any cuttings at
all. Wood powder would be the only result.
•
A sharp chain eats its way through the wood and
produces long, thick cuttings. The cutting part of the
chain is called the cutting link and this consists of a
cutting tooth (A) and the raker lip (B). The cutting
depth is determined by the difference in height
between the two.
•
When you sharpen a cutting tooth there are five
important factors to remember.

ARNING! The risk of kickback is
increased with a badly sharpened chain!
