FELL A TREE
Figure 9-10.
It is recommended that the first-time user should, as
a minimum practice, cutting logs on a saw-horse or
cradle.
Before you start to fell a tree, make sure that
•
The minimum distance between the areas of
bucking and felling is two times the height of the
tree.
•
The operation does not
•
Cause injury to personnel.
•
Hit utility lines. If the tree touches utility lines,
immediately tell the utility company.
•
Cause losses in property.
•
The user is not in the dangerous area, for example,
the downhill side of the area.
•
The escape paths that extend back and diagonally
behind the felling direction are clear. The felling
direction is controlled by
•
The natural lean of the tree.
•
The location of larger branches.
•
The wind direction.
•
There are no dirt, stones, loose bark, nails, and
staples on the tree.
1. Make a lower level notching cut. Make sure that
this cut is
a) 1/3 width of the diameter of the tree.
b) Perpendicular to the felling direction.
WARNING
English
The level notching cut helps prevent pinching of
the saw chain or the guide bar when you make the
second notch.
2. Make the felling cut no less than 50 mm and
higher than the level notching cut. Make sure
that this cut
a) Is parallel to the level notching cut.
b) Keeps sufficient wood to become a hinge which
prevents the tree from twisting and felling to the
wrong direction.
When the felling cut gets near the hinge, the tree
falls. Stop the felling cut if the tree
•
Does not fall to the correct direction or
•
Moves backwards, causing the cutting bar and
chain to become stuck in the cut.
3. Use felling wedge to open the cut and let the tree
fall to the correct direction.
4. When the tree starts to fall,
a) Remove the chainsaw from the cut.
b) Stop the machine.
c) Put the machine down.
d) Go away through the escape path. Be careful
with overhead branches and your footing.

LIMB A TREE
Figure 11.
Limbing is to remove the branches from a fallen tree.
1. Keep the larger lower branches to hold the log off
the ground.
2. Remove the small limbs in one cut.
3. Limb the branches with tension from the bottom to
up.
4. Keep the larger lower branches as a support until
the log is limbed.
4.8
BUCK A LOG
Figure 12-15.
Bucking is to cut a log into lengths. Keep your body
balance. If it is possible, lift the log and hold it with
branches, logs or chock.
•
When the log is held along the full length, cut it from
the top.
•
When the log is held on one end,
1. Cut the first time 1/3 of the diameter from the
bottom.
2. Cut the second time from the top to complete the
bucking.
•
When the log is held on two ends,
