Sharpening your chain and adjusting depth gauge setting

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 chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.

•A sharp chain eats its way through the wood and produces long, thick chips or shavings.

•The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge

(B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting).

When you sharpen a cutting tooth there are four important factors to remember.

1 Filing angle

2 Cutting angle

3File position

4Round ﬁle diameter

It is very difﬁcult to sharpen a chain correctly without the right equipment. We recommend that you use our ﬁle gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

See instructions under the heading Technical data for information about sharpening your chain.

WARNING! Departure from the

increases the risk of kickback.

Sharpening cutting teeth

To sharpen cutting teeth you will need a round ﬁle and a ﬁle gauge. See instructions under the heading Technical data for information on the size of ﬁle and gauge that are recommended for the chain ﬁtted to your chain saw.
