Bucking
This refers to sawing up a felled tree trunk
into smaller sections.
Ensure that you are in a secure position
and that your body weight is distributed
evenly on both feet. If possible, under-
pin and support the stem with branches,
beams or wedges.
•
Ensure that the saw chain does not
come in contact with the ground during
sawing.
•
Make sure you have a secure stance
and, in the case of sloping ground,
stand above the log.
To maintain full control at the moment
of "sawing through", reduce the contact
pressure at the end of the cut, without
releasing the firm grip on the chain saw
handles. Once cutting is complete, wait
for the saw chain to come to a stand-
still before removing the chain saw
from there. Always switch off the chain
saw before changing from tree to tree.
1. Log is lying on the ground:
K
Saw through the log completely
from above and ensure at the
end of the cut not to contact the
ground.
If you can turn the tree trunk,
saw two-thirds of the way
through it. Then turn the trunk
around and saw the rest of the
way through from above.
2. Log is supported at one end:
L
Start sawing from the bottom
and work your way up (with the
upper edge of the bar) a third of
the way into the diameter of the
trunk to prevent splitting. Then
saw from the top downwards
with the lower edge of the bar
towards the first cut to prevent
the bar from becoming jammed
in the wood.
3. Log is supported at both ends:
M
Start from the top and work
down (with the lower edge of the
bar) to a third of the diameter of
the trunk. Then saw from under-
neath with the upper edge of the
bar until the two cuts meet.
4. Sawing on a sawhorse:
N
Hold the electric chainsaw
steady with both hands, keep-
ing the saw in front of you while
sawing. Once the saw is through
the wood, guide the machine
passed you on the right (1). Hold
your left arm as straight as you
can (2). Watch out for the falling
trunk. Position yourself to pre-
vent any danger from the sepa-
rated trunk. Watch your feet. The
trunk may cause injuries when
falling. Keep your balance (3).

Limbing
Limbing is the designation for the sawing
off of branches and boughs from a felled
tree.
Many accidents occur during the
removal of branches. Never cut
tree limbs when you are standing
on the log. Keep the spring-back
area in mind if branches are un-
der tension.
•
Do not remove support branches until
after the sawing off.
•
Branches under tension must be
sawed from below to above, in order to
prevent jamming of the chainsaw.
When working on thicker branches,
use the same technique as when you
