file and gauge that are recommended for the saw chain
fitted to 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. See instructions under
To tension the saw chain on page 33
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 chainsaw 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 should be replaced.

General advice on adjusting the 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
320 - 005 - 27.09.2017
Filing equipment and
filing angles on page 41 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!
To adjust the depth gauge setting
Sharpen the cutting teeth before adjusting the depth
gauge setting. See heading
on page 32 . We recommend that you adjust the depth
gauge setting every third time you sharpen the cutting
teeth.
Note: This recommendation assumes that the length of
the cutting teeth is not reduced excessively.
You will need a flat file and a depth gauge tool to adjust
the depth gauge setting. We recommend that you use
our depth gauge tool to acheive the correct depth gauge
setting and bevel for the depth gauge.
1. Place the depth gauge tool over the saw chain.
Detailed information regarding how to use the depth
gauge tool, will be found on the package of the depth
gauge tool.
2. File off the tip of the depth gauge that protrudes
through the depth gauge tool. Use the flat file.
The depth gauge setting is correct when you no longer
feel resistance as you draw the file along the depth
gauge tool.
