Plunge cut
Plunge cutting is done
by
starting the cut with the lower
portion of the bar-tip and then moving
in
a straight forward
path.
Plunge cuts with a chain saw are made primarily when
using the heart-cut technique, if the log diameter is larger
than double the length of the guide bar and also when
felling oblique trees. They are also useful for strain relief
in
bucking. Plunge cutting requires extreme cautiony!
Apply the guide bar obliquely to the log rather than
perpendicularly:""Plunge
in
the guide bar nose until the bar
penetrates the log
by
the double of
'its
width. Then do the
actual plunge cut. Keep the saw from kicking back.
Lying or standing timber under strain should be first cut at
the compression side and then cut through the tension
side. This is important to prevent the saw from pinching or
kicking back.
s nlng!
This cutting methods are extremely hazardous and should
only be attempted by experienced cutters.
