other way round increases the risk of injury
and is not permitted.
c)
Always hold the chain saw by the insulated
handles because the saw chain may touch
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 equip‐
ment for hearing, head, hands, legs and feet is
recommended. Suitable protective clothing
helps reduce the risk of injury from flying wood
chips and accidental contact 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 situa‐
tions.
f)
Always keep proper footing and operate the
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.
i)
Carry the chain saw by the front handle with
the chain saw switched off and the saw chain
away from your body. When transporting or
storing the chain saw, always fit the protective
cover. Proper handling of the chain saw will
reduce the likelihood of accidental contact with
the moving saw chain.
j)
Follow the instructions for lubricating, chain
tensioning and changing the guide bar and
saw chain. Improperly tensioned or lubricated
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, plastic,
masonry or non-wood building materials. Use
of the chain saw for operations different than
intended could result in a hazardous situation.
l)
Do not attempt to fell a tree before you under‐
stand 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 chain saw and for
storing or servicing the chain saw. Make sure
that the switch is off and the battery block is
disconnected. Accidental startup of the chain
saw while servicing it or clearing it of accumu‐
lated material may cause severe injuries.
25.9 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 tool misuse and/or incor‐
rect operating procedures 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 bars and chains speci‐
fied by the manufacturer. Incorrect replace‐
ment bars and chains may cause chain break‐
age 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.
