lengthen considerably.

The chain life of the saw chain mainly depends upon
sufficient lubrication and correct tensioning.
Avoid tensioning the chain if it is hot, as this will
cause the chain to become overtensioned when it
cools down.
1. Place the chain saw on any suitable flat surface.
2. Turn locking knob 14 approx. 1 – 3 turns anti-
clockwise to loosen the chain bar.
3. Check if the chain links are correctly located in
the slot around the chain bar 11 and drive
sprocket 21.

4. Turn the red tensioning ring 13 clockwise ratchet-
ing until the correct chain tension is reached. The
ratchet mechanism prevents the chain tension
from loosening. The locking knob 14 may also
turn, when turning the tension ring 13. If the ten-
sioning ring 13 is hard to turn, loosen the locking
knob 14 once more anticlockwise.
5. The correct chain tension is reached when the
chain 10 can be raised approx. 3 – 4 mm from the
chain bar in the centre. This should be done by
using one hand to raise the chain against the
weight of the machine.
6. If the chain 10 is overtensioned, turn tensioning
ring 13 anticlockwise to loosen the chain.
7. If the chain 10 is tensioned optimal, lock the chain
bar 11 by tightening the locking knob 14 in clock-
wise direction. Do not use tools.
