the presence of spike bumpers, pivoting on
it. Study the tree and surrounding area before
starting to cut. Clear the work area before
beginning to cut. Prepare the widest possible
path of retreat for when the tree falls (Fig. 18).
Cut off any branches at the bottom of the trunk
up to a height of about 2 metres. Make a 90
degree notch on the face of the tree, in the
direction it will fall. The depth of the notch
should never exceed 1/4 of the diameter of the
trunk (1 - Fig. 19). About 10 cm (4") higher up
the trunk make a cut down towards the first cut,
in order to extract a wedge. This is the mouth of
the hinge, and is the direction in which the tree
falls (2 - Fig. 19).
Now, make your felling cut on the opposite
side of the trunk. Start the cut about 4-5 cm (2")
higher than the center of the notch (3 - Fig. 19).
Always leave a hinge (A, Fig. 20) which allows
you to control the direction the tree falls in.
Put a wedge into the felling cut, before the tree
starts to move, to prevent the electric chainsaw
guide bar from getting stuck.
LIMBING
a) Always start from the larger diameter and
move towards the tip to cut off limbs and
any secondary branches.
b) Always assume the most stable and safe
position possible before starting the electric
chain saw. If necessary, keep your balance by
resting your knee on the trunk itself.
c) Hold the electric chain saw in contact with
the tree trunk to minimize fatigue, turning
it to the right or left in accordance with the
position of the limb you wish to cut (Fig. 21).
d) In the case of branches under tension, find a
safe position to protect yourself if they whip
back. Always start the cut from the opposite
side to the bend.
WARNING - Do not use the upper edge
of the tip of the guide bar to cross-cut;
otherwise you might risk a kickback.
BUCKING
When bucking up the trunk to desired lengths,
there is one basic rule to follow. Look to see
where the trunk is supported, and determine
which way the two halves will fall when cut.
a) If the trunk is supported at both ends, first
make a small cut at the top (1 - Fig. 22),
then complete the cut from the bottom
(2 - Fig. 22). This will avoid pinching the saw.
b) If the trunk is supported at one end or
near the center, first make a small cut from
underneath (1 - Fig. 22), then complete the
cut from the top (2 - Fig. 22).
WARNING - If the saw becomes pinched
in the trunk, stop the motor, lift the log
and change its position. Never attempt to
free the saw by pulling on it.
Use the bucking tooth (Fig.23) to fi x the tool to
the timber before starting the cut so that it can
be used as a point of leverage during the cut.
PRECAUTIONS FOR THE WORK AREA
- Never cut in the vicinity of other electrical
cables.
- Always cut from a firm-footed and safe
position. Only start cutting when the chain is
moving. During work use the teeth as a
support point.
- The cut must be carried out so as to prevent
the guide bar from sticking in the wood.
- Do not expose the electric saw to rain or
high humidity conditions.
- Work only in conditions offering sufficient
visibility and light to see clearly.
- Be particularly cautious and alert when
wearing ear protectors, as these can restrict
your ability to hear sounds indicating danger
(shouts, signals, warnings, etc.)
- Be extremely careful when working on
slopes or uneven surfaces.
- Stop the motor before setting the chain saw
down.
- Do not lean forward and do not cut above
shoulder height; gripping the saw at the top
of the handle makes it difficult to control and
counteract kickback (Fig. 24).
- Do not use in trees or on steps, this is
extremely dangerous (Fig. 24).
