Warning! If felling a tree on sloping ground,
the chain saw operator should keep on the
uphill side of the terrain, as the tree is likely
to roll or slide downhill after it is felled.
Felling atree
Note: Direction of fall (B) is controlled by the notching
cut. Before any cuts are made, consider the location
of larger branches and natural lean of the tree to
determine the way the tree will fall.
Warning! Do not cut down a tree during high
or changing winds or if there is a danger to
properly. Consult a tree professional. Do not
cut down a tree if there is a danger of striking
utility wires; notify the utility company before
making any cuts.
General guidelines for felling trees
Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D). Start
making the upper notch cut (C) on the side of the
tree facing the felling direction (E). Be sure you don't
make the lower cut too deep into the trunk. 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 3-5cm
above the edge of the notch (C) (Fig. 11b).
Warning! Don't use the saw above shoulder-
height, because of difficult handling of the
chainsaw which can cause serious injury.
Take care of a stable position so you have
good control on the chain saw.
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 felling lever in the
cut well before the tree becomes unstable and starts
to move. This will prevent the guide bar from binding
in the felling cut if you have misjudged the falling
direction. Make sure no bystanders have entered the
range of the falling tree before you push it over.
Felling cut
1. Use wooden or plastic wedges (G) to prevent
binding the bar or chain (H) in the cut. Wedges
also control felling (Fig. 11c).
2. When diameter of wood being cut is greater than
the bar length, make 2 cuts as shown (Fig. 11d).
Warning! As the felling cut gets close to the
hinge, the tree should begin to fall. When
tree begins to fall, remove saw from cut,
unplug, put chain saw down, and leave area
along retreat path (Fig. 11a).
Limbing
Limbing a tree is the process of removing the branches
from a fallen tree. Do not remove supporting limbs (A)
until after the log is bucked (cut) into lengths (Fig. 12).
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.
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. When bucking on a slope, always
stand on the uphill side.
1. Log supported along entire length: Cut from top
(overbuck), being careful to avoid cutting into the
ground (Fig. 13a).
2. Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid
splintering. Second, cut from above (overbuck) to
meet first cut and avoid pinching (Fig. 13b).
3. Log supported on both ends: First, overbuck
1/3 diameter of log to avoid splintering. Second,
underbuck to meet first cut and avoid pinching
(Fig. 13c).
Note: The best way to hold a log while bucking is to
use a sawhorse. When this is not possible, the log
should be raised and supported by the limb stumps or
by using supporting logs. Be sure the log being cut is
securely supported.
Bucking using a sawhorse
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 14).
Vertical cutting:
A. Hold the saw firmly with both hands and keep the
saw to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.
Caution! While the saw is cutting, be sure the
chain and bar are being properly lubricated.

Warning! Ensure that the power cord is
disconnected before performing any
maintenance on your saw.
