NOTICE
Do not cut a lying log at a point where it
is touching the ground because the saw
chain will otherwise be damaged.
Ripping cut:
Cutting technique in which the spiked
bumper is not used – risk of pull-in – start
the cut with the guide bar at the
shallowest possible angle – take extra
care since there is an increased danger
of kickback.
Preparations for Felling
Check that there are no other persons in
the felling area – other than helpers.
Make sure no-one is endangered by the
falling tree – the noise of your engine
may drown any warning calls.
Maintain a distance of at least 2 1/2 tree
lengths from the next felling site.
Determine direction of fall and escape
path.
Select gap in stand into which you want
the tree to fall.
Pay special attention to the following
points:
– The natural lean of the tree
– Any unusually heavy limb structure,
damage
– The wind direction and speed – do
not fell in high winds
– Sloping ground
– Neighboring trees
– Snow load
– Soundness of tree – take special
care if trunk is damaged or in case
of deadwood (dry, decayed or rotted
wood)
