Note for practical use
Kick-back
Sawing accidents can be avoided if you do not saw
with the tip of the guide rail (7), because the saw can
then suddenly kick up and back.
Always wear full protective equipment and sturdy
work clothes when working with the saw.
Kickback is an upward and/or backward movement of
the guide rail (7) that can occur when the saw chain
(4) hits an obstacle (object) at the tip of the saw (7).
Always secure your workpiece well. Use clamping
devices to hold the workpiece in place. This makes
it easier to safely operate the chainsaw with both
hands.
Kickback causes uncontrollable behaviour of the
saw, this danger is particularly present with a loose or
blunt saw chain (4). An insufficiently sharpened chain
increases the risk of kickback. Never saw above
shoulder height.
Tips for sawing in practice
Important information
• Only use the device for sawing wood. Do not ma-
chine metal, plastic, masonry, non-wood building
materials, etc.
• Switch off the motor if the saw comes into contact
with a foreign object. Check the saw and repair it if
necessary.
• Protect the chain from dirt and sand. Even small
amounts of dirt can quickly dull the chain and in-
crease the risk of kickback.
• Start by sawing smaller logs for practice to get a
feel for your device before tackling more difficult
tasks.
• Press the housing of the electric chainsaw against
the tree trunk when you start sawing.
• Let the saw work for you. Apply only light down-
ward pressure.
• To avoid losing control of the device after the chain
has come out of the wood, do not apply pressure to
the saw towards the end of the cut.
Felling trees - only with appropriate training
Caution! Watch out for broken or dead branches that
can fall down during sawing and cause serious inju-
ries. Do not saw near buildings or power lines if you
do not know which way the felled tree will fall. Do not
work at night, as this makes it harder to see, or in
rain, snow or storms, as the direction of tree fall is
unpredictable.
• Plan your work with the electric chainsaw in ad-
vance.
• The work area around the tree should be clear so
that you have a secure footing.
• When sawing on a slope, the machine operator
should always stay on the higher level of the work
area because the tree is likely to roll or slide down
after felling.
• Look out for broken or dead branches that could
fall and cause serious injury.
The following conditions can influence the direc-
tion of fall of a tree:
• Wind direction and speed
• Inclination of the tree. The inclination is not always
recognisable due to uneven or sloping terrain. De-
termine the inclination of the tree using a plumb
bob or spirit level.
• Branch growth (and thus weight) on one side only.
• Surrounding trees or obstacles
If cutting and felling is done by two or more persons
at the same time, the distance between the felling
and cutting persons should be at least twice the
height of the tree to be felled. When felling trees,
care must be taken not to expose other persons to
danger, not to hit supply lines and not to cause dam-
age to property. Should a tree come into contact with
a supply line, the utility company must be informed
immediately.
Look out for destroyed and rotten parts of the tree.
If the trunk is rotten, it can suddenly break and fall
on you. Ensure that there is sufficient space for the
falling tree. Keep a clearance of 2 1/2 tree lengths to
the nearest person or other objects. Motor noise can
drown out warning calls.
Remove dirt, stones, loose bark, nails, staples and
wire from the sawing point.
Keep an escape route clear (Fig. A)
Before felling, an escape route should be planned
and cleared if necessary. The escape route should
lead away from the expected fall line at an angle to
the rear (Fig. A).
Position 1: Evacuation route
Position 2: Falling direction of the tree
Felling of large trees - only with appropriate train-
ing (from 15 cm diameter)
The undercutting method is used to fell large trees.
A wedge is cut out of the side of the tree according
to the desired direction of fall. After the drop cut has
been made on the other side of the tree, the tree falls
towards the wedge.
Note: If the tree has large supporting roots, these
should be removed before the notch is cut. If the saw
is used to remove the supporting roots, the saw chain
should not touch the base so that the chain does not
become blunt.
