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).
O
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 stand-
ing on the log. Keep the spring-
back area in mind if branches
are under 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
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 sepa-
rately.
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 electric
chainsaw if you feel unsure
about anything.
•
Ensure that no people or animals
are in the field of action. The safety
distance 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 character-
istic 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-
18 cm, can usually be sawn off with
one cut.
•
In case of trees with a larger diameter,
a notched cut and a back cut must be
implemented (see diagram
GB
).
