Making sapwood cuts
: For medium sized or larger trees
make cuts at both sides of the trunk,
: at same height as subsequent
felling cut.
: Cut to no more than width of guide
bar.
This is especially important in softwood
in summer - it helps prevent sapwood
splintering when the tree falls.

B = Felling cut
Conventional and open-face technique:
: Begin 1 to 2 inches (2.5 to 5 cm)
higher than center of felling notch
: Cut horizontally towards the felling
notch
: Leave approx.1/10 of diameter
uncut. This is the hinge
: Do not cut through the hinge - you
could lose control of the direction of
the fall
Drive wedges into the felling cut where
necessary to control the fall.
!
Warning!
If the tip of the bar contacts a wedge, it
may cause kickback. Wedges should be
of wood or plastic - never steel, which
can damage the chain.

Warning!
In order to reduce the risk of personal
injury, never stand directly behind the
tree when it is about to fall, since part of
the trunk may split and come back
towards the operator (barber-chairing),
or the tree may jump backwards off the
stump. Always keep to the side of the
falling tree. When the tree starts to fall,
withdraw the bar, shut off the engine and
walk away on the preplanned escape
path. Watch out for falling limbs.
