Poulan PLN3516F - Manual (Page 14)

The notch (C) should be deep enough to
create a hinge (F) of sufficient width and
strength. The notch should be wide
enough to direct the fall of the tree for as
long as possible.
WARNING
Never walk in front of a tree that has been
notched.
Make the felling cut (D) from the other side
of the tree and 1.5 - 2.0 inches (3~5 cm}
above the edge of the notch (C)
{Figure 5-1B),
Never saw completely through the trunk.
Always leave a hinge. The hinge guides
the tree. If the trunk is completely cut
through, control over the felling direction is
lost.
insert a wedge or feiling lever in the cut
well before the tree becomes unstable and
starts to move. This will prevent the guide
bar from binding in the feiling cut if you
have misjudged the falling direction. Make
sure no bystanders have entered the range
of the tailing tree before you push it over.
WARNING
Before making the final cut, always
recheck the area for bystanders, animals
or obstacles,
FELLING CUT:
1. Use wooden or plastic wedges (G) to
prevent binding the bar or chain (H) in
the cut. Wedges also control felling
(Figure 5-1C).
2, When diameter of wood being cut is
greater than the bar length, make 2
cuts as shown (Figure 5-1D),
WARNING
As the feiling cut gets dose to the hinge,
the tree should begin to fall. When tree
begins to fall, remove saw from cut, stop
engine, put chain saw down, and leave
area along retreat path (Figure 5-1 A).

5-2. LIMBING
Limbing a tree is the process of removing
the branches from a fallen tree. Do not
remove supporting iimbs (A) until after the
log is bucked (cut) into lengths (Figure
5-2A). Branches under tension should be
cut from the bottom up to avoid binding the
chain saw.
WARNING
Never cut tree limbs while standing on tree
trunk.
5-3. BUCKING
Bucking is cutting a fallen log into lengths.
Make sure you have a good footing and
stand uphill of the log when cutting on
sloping ground. If possible, the log should
be supported so that the end to be cut off
is not resting on the ground. If the log is
supported at both ends and you must cut
in the middle, make a downward cut
halfway through the log and then make the
undercut. This will prevent the log from
pinching the bar and chain. Be careful that
the chain does not cut into the ground
when bucking as this causes rapid
dulling of the chain.
