General advice on setting raker clearance
Tensioning the chain
•
When you sharpen the cutting teeth you reduce the raker
clearance (=cutting depth). To maintain optimal cutting
performance you must file back the raker lip to the
recommended height.
See the Technical data section to find the raker clearance
for your particular chain.
!
WARNING! A slack chain may jump off and
cause serious or even fatal injury.
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.
•
On a low-kickback cutting link the front edge of the raker
lip is rounded. It is very important that you maintain this
radius or bevel when you adjust the raker clearance.
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.
•
We recommend that you use our raker gauge to achieve
the correct clearance and bevel on the raker lip.
WARNING! The risk of kickback is increased
if the raker clearance is too large!

•
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.
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.
•
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.
To adjust the raker clearance you will need a flat file and a
raker gauge.
•
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.
•
•
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.
