Warning! The risk of kick-back increases when:
• file-angle is too big
• cutting-angle is too small
• diameter of round file is too small
B. Sharpening the teeth (Fig. 19)
To sharpen the teeth of the saw you need a round file and a file
mould. Consult a specialist store in chain saws for these items.
1. Check if the chain is stretched out completely. Otherwise the
chain is not stable enough and cannot be sharpened correctly.
2. Always file from the inside of the tooth to the outside. Always
lift up the file when you start sharpening another tooth. First
file all teeth on one side, turn round the chain saw and then
file the teeth on the other side.
3. After filing, the teeth should all have the same length. When
the length of the teeth is only 4 mm, the chain is worn and
should be replaced.
C. The cutting-depth
When you sharpen the teeth, the cutting-depth will decrease. To
maintain the maximum saw capacity, the ridge (B) has to be
lowered. To attain a perfect cutting-depth you should use also a
depth-mould. Consult a specialist store in chain saws for the specific
tools and measurements. Adjusting the cutting-depth has to be
done directly after the teeth are sharpened. You use a flat file and a
depth-mould for this. The cutting-depth is correct when you don’t
feel resistance anymore, while moving the file across the mould.
