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.
