determined by the length of the bar, the chain pitch
and the number of teeth on the bar tip sprocket.
• Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
• Chain oil hole and hole for chain tensioner. The bar
must be matched to the chain saw design.

General information 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 four important
factors to remember.
1 Filing angle
2 Cutting angle
3 File position
4 Round file diameter
