9. OPERATING INSTRUCTIONS
FIG. 22
FIG. 23
FIG. 24
– Delimb the tree up to shoulder height of all
branches. If the tree has large buttress roots 4
also remove these to enable the direction notch to
be cut as close to the ground as possible.
– The direction notch 5 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 6 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
7 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. 24
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 (U)
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 (V) will be made all the way through
with the underside of the guide bar.
– The third cut (W) 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.
