make a connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a fire.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritations or burns.
• Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or
risk of injury.
• Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
Service
• 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.
• Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.

General chain saw safety warnings

• 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
you clothing or body with the saw chain.
• 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.
• Hold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring. Saw chains contacting a "live" wire may make
exposed metal parts of the chain saw "live" and
could give the operator an electric shock.
• Wear eye protection. Further protective equipment
for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment will
reduce personal injury from flying debris or
accidental contact with the saw chain.
• Do not operate a chain saw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation of
a chain saw in this manner could result in serious
personal injury.
• Always keep proper footing and operate the chain
saw only when standing on fixed, secure and level
6
surface. Slippery or unstable surfaces may cause a
loss of balance or control of the chain saw.
• 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.
• 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 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.
• Follow instructions for lubricating, chain tensioning
and changing the bar and chain. Improperly
tensioned or lubricated chain may either brake or
increase the chance for kickback.
• Cut wood only. Do not use chain saw for purposes
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 intended could result in a hazardous
situation.
• 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 operator or
bystanders while felling a tree.
• 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.
• Do not operate a chain saw in a tree unless you
have been specifically trained to do so. Operation of
a chain saw in a tree without proper training could
increase the risk of serious personal injury.

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.
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
