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 be-
coming 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 underneath
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, keeping
the saw in front of you while saw-
ing. 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 prevent any
danger from the separated trunk.
Watch your feet. The trunk may
cause injuries when falling. Keep
your balance (3).
Limbing
O
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 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-

Felling trees
A lot of experience is neces-
sary in felling trees. Cut down
trees only when you can safely
handle 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
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.
