Precautions Against Kickback - Scheppach 5910114903 Originalbetriebsanleitung

Use the chainsaw and accessories only as described
in these instructions, taking into account the working
conditions and the work to be performed. Use of ma-
chine tools for operations different from those intend-
ed could result in a hazardous situation.
■ Check the chain brake is in good working order reg-
ularly (front hand guard, see fig. D).
■ Check that the guide rail is correctly fitted.
■ Check that the saw chain is correctly tensioned.
Follow the instructions for lubrication, chain ten-
sion and changing accessories. An incorrectly ten-
sioned or lubricated chain can break or increase
the risk of kickback.
■ Keep cutting tools sharp and clean. Sharpen them
regularly and replace worn parts promptly. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
■ Check the throttle control and the throttle control
lock for freedom of movement. The throttle control
must spring back into the start position.
■ Check whether there is enough fuel and chain lubri-
cation oil in the tank.
■ Check whether the handles are clean, dry and free
of oil and dirt.
■ Never carry out the work alone. In case of emer-
gency, someone should be close by.
■ Use the chainsaw only if you are standing on firm,
safe and even ground. Do not overreach. Slippery
ground or unstable standing surfaces (e.g. on a
step ladder) can lead to a loss of balance or loss
of control of the chainsaw. Keep proper footing and
balance at all times. This enables better control of
the chainsaw in unexpected situations.
■ Do not work with the chainsaw in a tree. When
working in a tree there is a risk of injury.
■ Never saw above shoulder height.
■ Always hold the chainsaw with your right hand on
the rear handle and your left hand on the front han-
dle (see fig. E). Holding the chainsaw in an inverted
working posture increases the risk of injuries and
is prohibited.
■ When the chainsaw is running, keep all body parts
away from the saw chain. Before starting the chain-
saw, make sure that the saw chain is not touching
anything. When working with a chainsaw, a mo-
ment of inattentiveness can lead to clothing or body
parts getting caught in the saw chain.
■ Switch the chainsaw off immediately if you notice
any changes in the way the appliance behaves.
■ If the chainsaw hits a stone, nails or other hard ob-
jects, stop the engine immediately and check the
saw chain and the guide rail for damage.
■ Do not drop the chainsaw, knock it against obstruc-
tions and do not use the guide rail as a lever.
■ Use the chainsaw only for sawing wood.

■ When sawing a branch that is under tension, expect
it to spring back. Once the tension in the wooden
fibres is released, the branch can hit the operator
and/or knock the chainsaw out of his hands.
■ Be extremely careful when cutting brushwood and
young trees. The thin material can catch in the saw
and fly in your direction or knock you off balance.
6.7 Vibrations
m WARNING
You can reduce the vibration risk, e.g. the risk of Ray-
naud's phenomenon (circulatory problems), by taking
regular breaks during which you rub your hands to-
gether.
■ Always wear protective gloves and ensure your
hands are warm.
■ Make sure that the chain is always sharp.
■ Take regular work breaks.

6.8 Precautions against kickback

m WARNING
Be aware of the danger of kickback when working
with the appliance. There is a risk of personal injury.
You can avoid kickbacks by being careful and using
the correct sawing technique.
■ Contact with the tip of the rail can, in some cases,
lead to an unexpected rearwards reaction resulting
in the guide rail flying upwards towards the operator
(fig. O).
■ Kickbacks can occur if the tip of the guide rail
touches an object or if the wood bends and the saw
chain gets caught in the cut.
■ If the saw chain jams in the upper edge of the guide
rail, the rail can kick back violently towards the op-
erator (see fig. J).
■ If the saw chain jams in the lower edge of the guide
rail, the rail can jerk violently away from the opera-
tor (see fig. K).
■ Be extremely careful when reapplying the chain of
the chainsaw to a cut you have already begun.
■ Do not saw any branches or pieces of wood that
can move their position during sawing or in which
the cut could close during sawing.
■ Any such reaction can lead to you losing control
over the saw and possibly injuring yourself. Do not
rely solely on the chainsaw's built-in safety devices.
As the user of a chainsaw, you can take a number
of measures to avoid accidents and injury.
