gauge setting. See
instructions about how to receive the correct depth
gauge setting for your saw chain.
(Fig. 118)
WARNING:
increases if the depth gauge setting is too
large!
To adjust the depth gauge setting
Before you adjust the depth gauge setting or sharpen
To sharpen the cutters on page 32 ,
the cutters, refer to
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.
(Fig. 119)
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 tighten the saw chain
WARNING:
correct tension can come loose from the
guide bar and cause serious injury or death.
The more you use a saw chain the longer it becomes. It
is important to adjust the saw chain regularly.
Do a check of the saw chain tension each time you refill
with chain oil.
Note:
A new saw chain has a running-in period during
which you must do a check of the tension more
frequently.
1. Fold the knob out until it opens. (Fig. 121)
2. Turn the knob counterclockwise to loosen the drive
sprocket cover. (Fig. 122)
3. Turn the chain tensioner wheel to adjust the tension
on the saw chain. The saw chain must be tight
against the guide bar. (Fig. 123)
Note:
Turn the wheel down (+) for more tension
and up (-) for less tension. The saw chain is
1259 - 003 - 14.09.2020
The risk of kickback
A saw chain without the
tightened correctly when you can turn is easily by
hand but is tight against the guide bar.
4. Turn the knob clockwise to tighten the bar knob.
(Fig. 124)
5. Fold down the knob to lock the tension. (Fig. 125)
To do a check of the saw chain
lubrication
Do a check of the saw chain lubrication each third
battery charge.
1. Start the product and let it run at 3/4 power. Hold the
bar approximately 20 cm (8 inches) above a light
coloured surface.
2. If the saw chain lubrication is correct, you will see a
clear line of oil on the surface after 1 minute. (Fig.
126)
3. If the saw chain lubrication is not correct, do the
following checks.
a) Do a check of the oil channel in the guide bar to
make sure that it is not blocked. Clean if
necessary. (Fig. 127)
b) Do a check of the groove in the edge of the guide
bar to make sure that it is clean. Clean if
necessary. (Fig. 128)
c) Make sure that the bar tip sprocket turns freely
and that the lubricating hole in the guide bar tip
sprocket is not blocked. Clean and lubricate if
necessary. (Fig. 129)
4. If the saw chain lubrication does not work after
following the steps above, speak to your servicing
dealer.
To do the maintenance on the chain
drive sprocket
The drive system has a drive sprocket.
(Fig. 130)
Do the following maintenance on the chain drive
sprocket:
1. Regularly do a check of the degree of wear on the
drive sprocket. Replace the chain drive sprocket if
there is too much wear.
2. Replace the drive sprocket when you replace the

saw chain.

To examine the cutting equipment
1. Make sure that there are no cracks in rivets and links
and that no rivets are loose. Replace if it is
necessary. (Fig. 131)
2. Make sure that the saw chain is easy to bend.
Replace the saw chain if it is rigid.
3. Compare the saw chain with a new saw chain to
examine if the rivets and links are worn.
