• Dirt,stones,loosebark,nails,clipsand
wires must be removed from the tree.
Do not fell any trees when
a strong or changing wind
is blowing, if the danger of
property damage exists or if
the tree could fall on electric
wires.

1. Removal of branches:
Remove hanging branches by positioning
the cut from above the branch. With re-
movalofbranches,neverworkhigherthan
shoulder level.
2. Escape area:
Remove the undergrowth around the tree to
ensure an easy escape. The escape area

hindtheplannedfellingdirection(2).
3. Cutting notch (A):
Make a felling notch in the direction in
which you wish the tree to fall. Start with
thebottom,horizontalcut.Thecutdepth
should be around 1/3 of the trunk diam-
eter. This will prevent the saw chain or the
guard rails from jamming when placing the
second chamfer. Now make a slanted saw

never step in front of a tree
which is notched.
4. Felling back cut (B):
Make the back cut from the other side of
thelog,whereyoustandtotheleftofthe
log and saw with the chainsaw pulling.
The back cut must run horizontally 5 cm
above the horizontal notched cut. The back
cut should be so deep that the separation
distance between the back cut and the
notch cutting line is at least 1/10 of the
trunk diameter. The part of the stem not
sawnthroughiscalledastay(fellinggib).
The stay prevents the tree from turning and
falling in the wrong direction. Do not saw
through the stay.
5. As you approach the felling cut
on the stay the tree should start
falling.Ifitbecomesapparentthatthetree

For safety reasons, we ad-
vise inexperienced users not
to fell any logs with a rail
length which is smaller than
the trunk diameter.

tree falls by itself or with the aid of the
felling wedge or crowbar.
