• Round file diameter.
It is very difficult to sharpen a saw chain correctly
without the right equipment. Zenoah recommends that
you use our file gauge. This will help you obtain the
maximum kickback reduction and cutting performance
from your saw chain.
WARNING: Departure from the sharpening
instructions considerably increases the risk
of kickback.
Note: See instructions under
angles on page 35 for information about sharpening
your saw chain.
To sharpen the cutting teeth
To sharpen cutting teeth you will need a round file and a
file gauge. See instructions under
filing angles on page 35 for information on the size of
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 28

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
filing angles on page 35 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 27 . 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
