Preparing work area at base of tree
– First clear the tree base and work
area from interfering limbs and
brush to provide a secure footing.
– Clean lower portion of tree base
(e.g. with an axe) – sand, stones
and other foreign objects will dull the
saw chain.
– Make the vertical cut first, then the
horizontal – but only if the wood is
sound
Making felling notch
There are several approved methods for
making the felling notch – observe
country-specific regulations on felling
techniques.
The felling notch (C) determines the
direction of fall.
STIHL recommends the following
method:
N Make the horizontal cut – check the
direction of fall with the gunning
sight.
N Make angle cut at about 45°.
N Check the felling notch and correct it
if necessary.
Important:
– Felling notch at a right angle to the
planned direction of fall.
– As close to the ground as possible.
– Cut to a depth of about 1/5 to 1/3 of
the trunk diameter.
Sapwood cuts
Sapwood cuts in long-fibered softwood
help prevent sapwood splintering when
the tree falls. Make cuts at both sides of
the trunk at same height as bottom of
felling notch to a depth of about 1/10 of
trunk diameter. On large diameter trees,
cut to no more than width of guide bar.
Do not make sapwood cuts if wood is
diseased.
