SPECIFIED CONDITIONS OF USE
Safety Instructions Hedge trimmer
Keep all parts of the body in safe distance from the
knife.Do not try to remove the material being cut or
hold material to be cut when the knife is running.
Jammed cuttings to be removed only when the
machine is off and the battery taken out. A moment of
inattention when using the hedge trimmer may result in
serious injuries.
Carry the hedge trimmer by the handle when the
knife is off. Fit the protective cover whenever the
hedge trimmer is to be transported or stored. Careful
treatment with the appliance reduces the risk of injury by
the blade. Hold the power tools by the insulated handles
as the cutting knife may come into contact with hidden
cables/lines. Contact of the cutting knife with a live con-
ductor may bring the metal parts of the appliance under
voltage and cause electric shock.
FURTHER SAFETY INSTRUCTIONS
Before work, check the area for any hidden
items such as wire fences.
When working, keep the appliance firmly with
both hands and with a distance from your
body.
Cordless-Chain saw
• 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.
• 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.
• 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 work on trees with the chainsaw. There is a risk
of injury when working on a tree.
• Always keep proper footing and operate the chain saw
only when standing on fixed, secure and level 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 sapli-
ngs. 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
40
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 tensi-
oned 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. 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.
• The machine is not protected against electric shock
when coming into contact with high-voltage lines.
Maintain a minimum clearance of 10 m from currentcar-
rying lines. Life-threatening danger from electric shock!
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.
Kickback is the result of tool 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 operator, if proper precautions are taken.
• Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
enables better control of the chain saw in unexpected
situations.
• Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement guide bars
and chains may cause chain breakage and/or kickback.
• Follow the manufacturer's sharpening and mainte-
nance instructions for the saw chain. Decreasing the
depth gauge height can lead to increased kickback.
