Open-face technique
A = felling notch - determines the
direction of the fall
For an open-face cut:
: Properly place felling notch
perpendicular to the line of fall,
close to the ground
: Cut down at app. 50-degree angle
to a depth of app.1/5 to 1/4 of the
trunk diameter
: Make second cut from below at app.
40 degree angle
: Remove resulting 90-degree piece
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 centre 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.
