To sharpen the saw chain

The cutter

The cutting part of the saw 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, the
depth gauge setting (C).
When you sharpen a cutting tooth there are four
important factors to remember:
• Filing angle.

• Cutting angle.

To sharpen the cutting teeth

Use a round file and a file gauge to sharpen the
cutting teeth. See
combinations on page 23 for information on the
recommended dimension of the file and gauge for
the saw chain installed on your product.
1. Make sure that the saw chain is correctly
tensioned. A slack chain will move sideways,
making it more difficult to sharpen correctly.
2. File all teeth on one side first. File the cutting
teeth from the inside face and reduce the
pressure on the return stroke.
3. Turn the product over and file the teeth on the
other side.
4. File all the teeth to the same length. When the
length of the cutting teeth is reduced to 4 mm
(5/32") the saw chain is worn out and must be
replaced.
