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 Husqvarna 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.
4. Tighten the saw chain until it is tight against the
guide bar but still can move easily.
5. Tighten the bar nuts using the wrench and lift the
front of the guide bar at the same time.
6. Make sure you can pull the saw chain around freely
by hand and that it does not hang from the guide
bar.
Note: Refer to
Product overview on page 2
for the
position of the chain tensioning screw on your product.
To do a check of the saw chain
lubrication
1. Start the product and let it operate at ¾ throttle. Hold
the bar approximately 20 cm/8 in above a surface of

line of oil on the surface after 1 minute.
3. If the saw chain lubrication does not operate
correctly, do a check of the guide bar. Refer to
