When repositioning for the next cut (2),
keep the guide bar fully engaged in the
kerf to keep the felling cut straight –
apply the spiked bumper again.
Insert a wedge (3) in the cut.
Last cut (4):
Apply the spiked bumper as for the
simple fan cut – do not cut through the
hinge!
Plunge cutting
Do not attempt plunge cuts if you are not
experience in this cutting technique.
– Use a low kickback chain and
exercise particular caution
– For heartwood cut
– For felling leaners
– For relieving cuts during bucking
– For DIY projects
Begin cut (1) by applying lower portion of
the guide bar nose – do not use upper
portion because of risk of kickback. Cut
until depth of kerf is twice the width of the
guide bar.
Swing saw slowly (2) into plunge-cutting
position. Take care because of the risk of
kickback or pushback.
Make the plunge cut (3) very carefully.
Danger of pushback.
Heartwood cut
Enlarge the plunge cut to both sides as
shown
– if tree diameter is more than twice
the length of the guide bar.
– if a large portion of heartwood
remains uncut on large diameter
trees.
– on trees that are difficult to fell (oak,
beech), to prevent heartwood
splintering and maintain planned
direction of fall.
– on soft deciduous trees to relieve
tension in lying log and prevent
slivers in the center of the hinge
being torn out of the log.
–
: Carefully make the plunge cut in the
center of the felling notch – there is
a danger of pushback at this
point – then swing the bar in the
direction of the arrow.
