Note:
Refer to
Accessories on page 34
for
information about which file and gauge that Zenoah
recommends for your saw chain.
2. Apply the file gauge correctly on to the cutter. Refer
to the instruction supplied with the file gauge.
3. Move the file from the inner side of the cutting teeth
and out. Decrease the pressure on the pull stroke.
4. Remove material from one side of all the cutting
teeth.
5. Turn the product around and remove material on the
other side.
6. Make sure that all cutting teeth are the same length.
General information about how to adjust the
depth gauge setting
The depth gauge setting (C) decreases when you
sharpen the cutting tooth (A). To keep maximum
cutting performance you must remove filing material
from the depth gauge (B) to receive the recommended
depth gauge setting. See Accessories on page 34
for instructions about how to receive the correct depth
gauge setting for your saw chain.

WARNING:
The risk of kickback
increases if the depth gauge setting is too
large!
To adjust the depth gauge setting
Before you adjust the depth gauge setting or sharpen
the cutters, refer to
To sharpen the cutters on page
28
, for instructions. We recommend you to adjust the
depth gauge setting after each third operation that you
sharpen the cutting teeth.
We recommend that you use our depth gauge tool to
receive the correct depth gauge setting and bevel for the
depth gauge.
1. Use a flat file and a depth gauge tool to adjust
the depth gauge setting. Only use a Zenoah
recommended depth gauge tool to get the correct
depth gauge setting and bevel for the depth gauge.
2. Put the depth gauge tool on the saw chain.
Note:
See the package of the depth gauge tool for
more information about how to use the tool.
3. Use the flat file to remove the part of the depth
gauge that extends through the depth gauge tool.
To adjust the tension of the saw chain
WARNING:
A saw chain with an
incorrect tension can come loose from the
guide bar and cause serious injury or death.
A saw chain becomes longer when you use it. Adjust the
saw chain regularly.
1. Loosen the bar nuts that hold the clutch cover/chain
brake. Use a wrench.
Note:
Some models have only one bar nut.
2. Tighten the bar nuts by hand as tightly as you can.
3. Lift the front of the guide bar and turn the chain
tensioning screw. Use a wrench.
