GENERAL SAFETY PRECAUTIONS
General advice on adjusting 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 Technical
data to find the correct depth gauge setting for your
particular chain. (8)

Adjustment of depth gauge setting
The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. 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. We
recommend that you use our depth gauge tool to
acheive the correct depth gauge setting and bevel for
the depth gauge.
Place the depth gauge tool over the chain. Detailed
information regarding the use of the depth gauge tool,
will be found on the package for the depth gauge tool.
Use the flat file to file off the tip of the depth gauge that
protrudes through the depth gauge tool.The depth
gauge setting is correct when you no longer feel
resistance as you draw the file along the depth gauge
tool.
Tensioning the chain
_proved-
| _ chain can cause serious cuts to yourself
| or persons you bump into with an
exposed chain.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A
new chain has a running-in period during which you
should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand. (10)
Switch the engine off. (30)
Release the knob by folding it out until it snaps open.
(11)
Turn the knob anti clockwise to loosen the bar cover.
il 2)
Adjust the tension on the chain by turning the chain
tensioner wheel down (+) for tighter tension and up (-
) to loosen the tension. Lift tip of guide bar while
adjusting tension. (13)
Tighten the clutch cover by turning the knob clockwise
while lifting tip of bar. (14)
Fold the knob back in to lock the tensioning. (15)
Lubricating cutting equipment

injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
Filling with chain oil
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a lean mixture may mean that the fuel
lasts longer than the oil) and that you also use the
recommended cutting equipment (a bar that is too
long will use more chain oil).
Checking chain lubrication
Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
Aim the tip of the bar at a light coloured surface about
20 cm (8 inches) away. After 1 minute running at 3/4
throttle you should see a distinct line of oil on the light
surface.
If the chain lubrication is not working:
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
