GENERAL SAFETY PRECAUTIONS

•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

2Cutting 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 sharpening

!instructions considerably 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.

•Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difﬁcult to sharpen correctly.

•Always ﬁle cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side ﬁrst, then turn the chain saw and ﬁle the teeth on the other side.

•File all the teeth to the same length. When the length of the cutting teeth is reduced to 0.16 inch (4 mm) the chain is worn out and should be replaced.

General advice on adjusting depth gauge setting

•When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be ﬁled down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to ﬁnd the correct depth gauge setting for your particular chain.

WARNING! The risk of kickback is increased

!if the depth gauge setting is too large!
