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.
Preparing for felling
Only persons who are engaged in felling
may be present in the felling area.
Make certain that no one is endangered
by the falling tree – engine noise can
drown out shouting.
