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:
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:
Hold the electric chainsaw steady
with both hands, keeping 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 your-
self to prevent any danger from
the separated 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,
40
use the same technique as when you
are sawing up a felled trunk.
•
Work to the left of the log and as near
as possible to the electric chainsaw.
As far as possible, the weight of the
saw should rest on the log.
•
Change position to saw off branches
on the other side of the trunk.
•
Branches sticking out are cut off
separately.
•
When taking off larger branches, lea-
ve the ones that extend downwards
and support the tree be for now. Saw
off smaller branches, as shown in Fi-
gure
, in one go.
Felling trees
A lot of experience is necessary
in felling trees. Cut down trees
only when you can safely han-
dle the electric chainsaw. In no
case should you use the elec-
tric chainsaw if you feel unsure
about anything.
•
Ensure that no people or animals are
in the field of action. The safety dis-
tance between the tree to be felled
and the nearest-located workplace
must be 2 ½ tree lengths.
•
Note the felling direction:
The user must be able to move safely
near the felled tree, to saw off the tree
easily and remove branches.It is to
be avoided that the felled tree snags
itself on another tree. Note the natural
felling direction, which is dependent
on the slope and curvature charac-
teristic of the tree, wind direction and
the number of branches.
•
In the case of sloping ground, stand
above the tree to be felled.
•
Small trees, with a diameter of 15-
