9 OPERATION & USE
– Delimb the tree up to shoulder height of all
branches. If the tree has large buttress roots 5
also remove these to enable the direction notch
to be cut as close to the ground as possible.
– The direction notch 6 should be started at 45º
down into approximately one third the trees
diameter.
– Cut the bottom of the notch at 90º and remove
the wedge. On the opposite side of the tree and
5cm higher than the bottom of the notch, the
felling cut
7
should be made at 90º. This cut
must be made in one go and stop 5cm from the
back of the notch. This creates the hinge which is
very important as it helps control the felling. The
hinge
8 must be parallel. Use the spiked
bumper to obtain a firm grip and leverage while
performing these cuts.
– The use of wedges should be employed to
prevent the saw becoming pinched and to
complete the fell safely.
9.10 DELIMBING (FIG.29)
Refer to general safety instructions for preparatory
and specific warnings.
– When removing smaller branches with a single
cut, keep the tree between you and chain.
– For larger limbs make three cuts. The initial cut
9
in the tensioned underside of the limb one
third of the way through. Use a pushing chain
(the top of the guide bar) for this.
– The second cut : will be made all the way
through with the underside of the guide bar.
– The third cut ; is only necessary if the tree is
not being felled, to leave a neat collar.
– On a felled tree always work from butt to tip
with the tree on your right side. Always work
with the trunk between you and the guide bar.
