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 obstruct-
ed.
Clean if necessary.
• Check that the groove in the edge of the bar is
clean.
Clean if necessary.
• 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.
If the chain lubrication system is still not working after
carrying out the above checks and associated meas-
ures you should contact your service agent.
Chain drive sprocket
The clutch drum is fi tted with a Spur sprocket (the chain
sprocket is welded on the drum).
Regularly check the degree of wear on the drive
sprocket.
Replace if wear is excessive. Replace the drive sprock-
et whenever you replace the chain.
Checking wear on cutting equipment
Check the chain daily for:
• Visible cracks in rivets and links.
• Whether the chain is stiff.
• Whether rivets and links are badly worn.
Replace the saw chain if it exhibits any of the points
above.
We recommend you compare the existing chain with
a new chain to decide how badly the existing chain is
worn.
When the length of the cutting teeth has worn down to
only 4 mm the chain must be replaced.
Bar
Check regularly:
• Whether there are burrs on the edges of the bar.
Remove these with a fi le if necessary.
• Whether the groove in the bar has become badly
worn.
Replace the bar if necessary.
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 fl at fi le 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
fl at fi le to fi le 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
fi le along the
depth gauge tool.
TENSIONING THE CHAIN
WARNING! A slack chain may jump off 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.
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.
LUBRICATING CUTTING EQUIPMENT
WARNING! Poor lubrication of cutting equip-
ment may cause the chain to snap, which
could lead to serious, even fatal injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its
fl ow characteristics regardless of
whether it is warm summer or cold winter weather.
Filling with chain oil
• All our chain saws have an automatic chain lubri-
cation system. On some models the oil fl ow is also
adjustable.
• The saw chain oil tank and the fuel tank are de-
signed 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 rec-
ommended cutting equipment (a bar that is too long will
use more chain oil).
