outside the specified range may damage the

24.7 Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the
power tool is maintained.
b) Never service damaged battery packs. Service
of battery packs should only be performed by
the manufacturer or authorized service provid‐
ers.
24.8 Safety instructions for chain
saws
General chain saw safety warnings
a) Keep all parts of the body away from the saw
chain when the chain saw is operating. Before
you start the chain saw, make sure the saw
chain is not contacting anything. A moment of
inattention while operating chain saws may
cause entanglement of your clothing or body
with the saw chain.
b) Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle. Holding the chain saw with a
reversed hand configuration increases the risk
of personal injury and should never be done.
c) Hold the chain saw by insulated gripping sur‐
faces only, because the saw chain may con‐
tact hidden wiring or its own cord. Saw chains
contacting a "live" wire may make exposed
metal parts of the chain saw "live" and could
give the operator an electric shock.
d) Wear eye protection. Further protective equip‐
ment for hearing, head, hands, legs and feet is
recommended. Adequate protective equip‐
ment will reduce personal injury from flying
debris or accidental contact with the saw
chain.
e) Do not operate a chain saw in a tree, on a lad‐
der, from a rooftop, or any unstable support.
Operation of a chain saw in this manner could
result in serious personal injury.
f) Always keep proper footing and operate the
chain saw only when standing on fixed, secure
and level surface. Slippery or unstable surfa‐
ces may cause a loss off balance or 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 fibres 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 away from
your body. When transporting or storing the
chain saw, always fit the guide bar cover.
Proper handling of the chain saw will reduce
the likelihood of accidental contact with the
moving saw chain.
j) Follow instructions for lubricating, chain ten‐
sioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kick‐
back.
k) Cut wood only. Do not use chain saw for pur‐
poses not intended. For 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 inten‐
ded could result in a hazardous situation.
l) Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them. Serious injury could occur to the opera‐
tor or bystanders while felling a tree.
m Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
)
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chain saw while clearing jammed material or
servicing may result in serious personal injury.
24.9 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.
