SAFETY INSTRUCTIONS
• We recommend that you use our raker gauge to achieve
the correct clearance and bevel on the raker lip.
Setting the raker clearance
• Before setting the raker clearance the cutting teeth should
be newly sharpened. We recommend that you adjust the
raker clearance every third time you sharpen the chain.
NOTE! This recommendation assumes that the length of
the cutting teeth is not reduced excessively.
• To adjust the raker clearance you will need a flat file and a
raker gauge.
• Place the gauge over the raker lip.
• Place the file over the part of the lip that protrudes through
the gauge and file off the excess. The clearance is correct
when you no longer feel any resistance as you draw the
file over the gauge.
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 new
chain has a running-in period during which you should check
the tension more frequently.
The position of the chain tensioning screw on our chain saws
varies from model to model. See the What is what? section to
find out where it is on your model.
Tension the chain as tightly as possible, but not so tight that
you cannot pull it round freely by hand.
• Undo the bar nuts that hold the clutch cover/chain brake.
Use the combination spanner. Then tighten the bar nuts
by hand as tight as you can.
• Raise the tip of the bar and stretch the chain by tightening
the chain tensioning screw using the combination
spanner. Tighten the chain until it does not sag from the
underside of the bar.
• Use the combination spanner to tighten the bar nuts while
lifting the tip of the bar at the same time. Check that you
can pull the chain round freely by hand and that it does not
sag from the underside of the bar.
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 vegetable 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.
In areas where oil specifically for lubrication of saw chains is
unavailable, ordinary EP 90 transmission oil may be used.
Never use waste oil! This is dangerous for yourself, the
machine and the environment.
!
WARNING! The risk of kickback is increased
if the raker clearance is too large!
!
WARNING! A slack chain may jump off and
cause serious or even fatal injury.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
