DANGER!
Risk of burn injury!
A too tightly tensioned chain can lead to motor overload
and damage or break of the chain, whereas insufficient ten-
sioning can cause the chain to jump off the rail. A correctly
tensioned chain offers the best cutting performance and
a longer service life. Therefore, you should check the ten-
sioning regularly as the chain may expand when being used
(especially when the chain is new; following first installation,
the tensioning of the chain must be checked after the chain-
saw has been used for a few minutes).
v However, do not tension the chain immediately after the
operation but wait until it has cooled down.
1. Lift the chain
should be approx. 2 – 3 mm.
2. Turn the adjustment screw
the chain is too low, or turn the adjustment screw
when the tensioning of the chain is too strong.
3. Start the unit for approx. 10 sec.
4. Check the tensioning of the chain again and re-adjust,
if necessary.
