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 batteries. Service of battery
packs should only be performed by the manufacturer or
authorized service providers.
24.8 Chain saw safety warnings
– Keep all parts of the body away from the saw chain when
the chain saw is operating, 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 chain saw.
– 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 the other way round increases the risk of injury
and may not be used.
– Always hold your chain saw by the insulated handles
because the saw chain may contact hidden electrical
wires or your own power cord. Any saw chain contact with
a live wire may energize metallic parts of the power tool
and result in an electric shock.
– Wear eye protection. Further protective equipment for
hearing, head, hands, legs and feet is recommended.
Suitable protective clothing helps reduce the risk of injury
from thrown wood chips and accidental contact with the
saw chain.
– Never work with a chain saw 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 chain saw
only when standing on a fixed, secure and level surface.
A slippery surface or instable support such as a ladder
could cause the operator to lose control of the chain saw.
– 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.

24 General Power Tool Safety Warnings
– 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 the chain saw
switched off and the saw chain away from your body.
When transporting or storing the chain saw always fit the
guide bar scabbard. Proper handling of the chain saw will
reduce the likelihood of accidental contact with the moving
saw chain.
– Follow instructions for lubricating, chain tensioning and
changing accessories. Improperly tensioned or lubricated
chain may either break or increase the chance for
kickback.
– Keep handles dry, clean and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
– Cut wood only. Do not use chain saw for purposes not
intended. Example: do not use chain saw for cutting
plastic, masonry or non-wood building materials. Use of
the chain saw for operations different than intended could
result in a hazardous situation.
– Do not attempt to fell a tree before you fully understand
the procedures involved. The user or other persons can
be seriously injured by a falling tree.
24.9 Causes and operator prevention 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.
