hidden electric wires. Any saw chain contact
with a live wire may energize metallic parts
of the power tool and result in an electric
shock.
d) Wear eye protection. Further protective
equipment for hearing, head, hands, legs
and feet is recommended. Suitable protec‐
tive clothing helps reduce the risk of injury
from flying wood chips and accidental con‐
tact with the saw chain.
e) Never work with a chain saw while standing
in a tree, on a ladder, on a roof or other
instable surface. There is a risk of injury in
such situations.
Always keep proper footing and operate the
f)
chain saw only when standing on a fixed,
secure and level surface. A slippery surface
or instable support could cause the operator
to lose control of the chain saw.
g) When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibers is released the spring loaded
limb may strike the operator and/or throw the
chain saw out of control.
h) Use extreme caution when cutting brush and
saplings. The slender material may catch the
saw chain and be whipped toward you or pull
you off balance.
Carry the chain saw by the front handle with
i)
the chain saw switched off and the saw chain
away from your body. When transporting or
storing the chain saw, always fit the protec‐
tive cover. Proper handling of the chain saw
will reduce the likelihood of accidental con‐
tact with the moving saw chain.
Follow the instructions for lubricating, chain
j)
tensioning and changing the guide bar and
saw chain. Improperly tensioned or lubrica‐
ted chain may either break or increase the
chance for kickback.
k) Cut wood only. Do not use chain saw for
other than the intended purposes. Example:
do not use chain saw for cutting metal, plas‐
tic, masonry or non-wood building materials.
Use of the chain saw for operations different
than intended could result in a hazardous sit‐
uation.
Do not attempt to fell a tree before you

understand the risks involved and how to
avoid them. The felling of a tree involves the
risk of severe injury to the saw operator and
for bystanders.

m) Follow all the instructions for removing accu‐
mulated material from the chainsaw and for
storing or servicing the chainsaw. Make sure
that the switch is set to "Off" and the battery
block has been removed.Unexpected startup
of the chainsaw during removal of accumula‐
ted material or during maintenance work may
cause severe injuries.
27.9 Causes and operator preven‐
tion of kickback
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and
back towards the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back
towards the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chain
saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
Kickback is the result of chain saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
– Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the oper‐
ator, if proper precautions are taken. Do not let
go of the chain saw.
– Do not overreach and do not cut above shoul‐
der height. This helps prevent unintended tip
contact and enables better control of the chain
saw in unexpected situations.
– Only use replacement guide bars and saw
chains specified by the manufacturer. Incor‐
rect replacement guide bars and saw chains
may cause chain breakage and/or kickback.
– Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead
to increased kickback.
