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 26 for
instructions about how to receive the correct depth
gauge setting for your saw chain.

To tighten the saw chain

WARNING: A saw chain without the 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. 123)
2. Turn the knob counterclockwise to loosen the drive
sprocket cover. (Fig. 124)
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. 125)
Note: Turn the wheel down (+) for more tension and
up (-) for less tension. The saw chain is 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. 126)
5. Fold down the knob to lock the tension. (Fig. 127)
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.
128)
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. 129)
