6.8 Precautionary measures against kick-back
m
WARNING
Watch out for kick-back when working with the device.
There is a danger of injury. Avoid kick-backs through
caution and correct sawing technique.
■
Touching with the tip of the guide bar can some-
times lead to an unexpected backward reaction,
whereby the guide bar whips up and in the direction
of the operator.
■
Kickback can arise if the tip of the guide rail touches
an object or if the wood bends and the saw chain
jams in the cut.
■
If the saw chain jams on the top edge of the guide
bar, the chainsaw can jerk back suddenly in the di-
rection of the operator (fig. I).
■
If the saw chain jams on the lower edge of the guide
bar, the chainsaw can jerk forward suddenly away
from the operator (fig. J).
■
Be extremely careful when using the chain of the
chainsaw to continue cutting into a cut that has al-
ready been started.
■
Do not saw branches or pieces of wood that could
change their position during the sawing process or
where the cut closes during the sawing process.
■
Each of these reactions can lead to you losing con-
trol of the saw and possibly suffering a serious in -
jury. Never rely solely on the safety equipment in-
tegrated in the chainsaw. As a chainsaw user, take
various measures to work without accidents and
injuries.
Kick-back is the result of incorrect or deficient use.
It can be prevented by suitable precautionary meas-
ures, as described in the following:
■
Hold the saw firmly with both hands, with the thumbs
and fingers enclosing the chainsaw handles. Bring
your body and arms into a position in which you
can absorb the kickback forces. If suitable meas-
ures are implemented, the operator will be able to
withstand the kick-back forces. Never let go of the
chainsaw (see fig. D).
■
Avoid an unusual body stance and never saw above
shoulder height. This will help to avoid unintentional
contact with the rail tip, and enable improved control
of the chainsaw in unexpected situations.
■
Always use replacement guide rails and saw chains
prescribed by the manufacturer. Incorrect replace-
ment guide bars and saw chains may cause the
saw chain to break and/or lead to kick-back.
■
Adhere to the instructions of the manufacturer when
sharpening and maintaining the saw chain. If the
depth limiter is too low, this increases the tendency
towards kick-back.
■
Do not saw with the tip of the guide bar. There is a
risk of kick-back.
■
Check that the throttle and the throttle interlock
move easily. The throttle lever must spring back to
the starting position.
■
Check that there is enough fuel and chain lubricat-
ing oil in the tank.
■
Check that the handles are clean, dry and free from
oil and dirt.
■
Never carry out the work alone. In an emergency,
someone must be nearby.
■
Only use the chainsaw when standing on firm,
safe and level ground. Do not overreach. Slippery
ground or unstable standing surfaces (e.g. on a lad-
der) can cause loss of balance or loss of control
of the chainsaw. Keep proper footing and balance
at all times. This will allow you to better control the
chainsaw in unexpected situations.
■
Do not work with the chainsaw in a tree. There is a
risk of injury when operating in a tree.
■
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. D). Holding the chainsaw using the op-
posite grip increases the risk of injuries and must
be avoided.
■
Keep all body parts away from the saw chain when
the chainsaw is running. Before starting the chain-
saw, ensure that the saw chain is not touching an-
ything. When working with a chainsaw, a moment
of carelessness can result in clothing or body parts
being caught by the saw chain.
■
Switch off the chainsaw immediately if you notice
any noticeable changes in the device’s behaviour.
■
If the chainsaw has come into contact with stones,
nails or other hard objects, stop the engine immediate-
ly and check the saw chain and guide bar for damage.
■
Do not drop the chainsaw, do not hit it against ob-
stacles and never use the guide bar as a lever.
■
Only saw in wood with the chainsaw.
■
When cutting a branch that is under tension, expect
it to spring back. If the tension in the wood fibres is
released, the tensioned branch can hit the operator
and/or wrest the chainsaw from control.
■
Be especially careful when cutting undergrowth and
young trees. The thin material can get caught in the
saw chain and hit you or throw you off balance.
6.7 Vibrations
m
WARNING
Avoid the risks associated with vibration, e.g. the risk
of white finger syndrome (circulatory disorders) by
taking frequent breaks from work where you rub your
palms together, for example.
■
Always wear protective gloves and make sure your
hands are warm.
■
Make sure that the chain is always sharp.
■
Take regular breaks from work.
