GENERAL SAFETY PRECAUTIONS
12 – English
5451546-92 Rev.3 2007-12-19
File all the teeth to the same length. When the length of the
cutting teeth is reduced to 0.16 inch (4 mm) the chain is
worn out and should be replaced.

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.
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 y
ou 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
inf
ormation 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
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
ne
w 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
y
ou cannot pull it round freely by hand.
(9)
• Release the knob by folding it out. (10)
• Turn the knob anti clockwise to loosen the bar cover.
(11)
• Adjust the tension on the chain by turning the wheel
down (+) for tighter tension and up (-) to loosen the
tension. Lift tip of guide bar while adjusting tension.
(12)
• Tighten the clutch cover by turning the knob clockwise
while lifting tip of bar.
(13)
• Fold the knob back in to lock the tensioning. (14)
Lubricating cutting equipment
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.
As a chain saw manufacturer we have developed an
optimal chain oil which has a v
egetable oil base. We
recommend the use of our own oil for both maximum chain
life and to minimise environmental damage. If our own
chain oil is not available, standard chain oil is
recommended.
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 r
uns out before the saw chain oil.
However, this safety feature requires that you use the
r
ight 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) a
way. 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 necessar
y.
• Check that the groove in the edge of the bar is clean.
Clean if necessar
y.
• Check that the bar tip sprocket turns freely and that the
lubricating hole in the tip sprocket is not blocked. Clean
and lubricate if necessary.
!
WARNING! The risk of kickback is
increased if the depth gauge setting is
too large!
!
WARNING! A slack chain may jump off
the bar and cause serious or even fatal
injury.
!
WARNING! Always wear approved
protective gloves. Even a non-moving
chain can cause serious cuts to yourself
or persons you bump into with an
exposed chain.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage. Otherwise there is a
risk of the saw chain oil oxidizing, which will result in the
saw chain becoming stiff and the bar tip sprocket
jamming.
