4.3.4 Saw blade (if permitted) (Fig. 18)
WARNING!
When using the saw blade,
where permitted, the specific guard must al-
ways be fitted. The blade must always be well
sharpened to reduce the risk of kickback.
WARNING!
When felling small trees, es-
timate the direction in which the cut tree will
fall, also taking the wind direction into con
-
sideration.
To get a good result when felling small trees,
the cut must be made with a rapid movement to
-
wards the branch or trunk to be cut, with the en
-
gine at maximum revs.
Do not use the right-hand area of the blade be-
cause there is a high risk of kickback or the blade
seizing up, due to the direction of rotation.

When you have finished your work:
– Stop the machine as indicated previously (see
3.3).
– Wait for the cutting device to stop and then
mount the blade guard.
