ments for operating the equipment.
•
Keep the equipment at a minimum distance
from overhead power cables.
•
Before you begin your work, make yourself
well acquainted with all the control elements.
Practice handling the equipment and have an
expert explain its functions, mode of operati-
on and sawing techniques.
•
Never use the equipment if you are ill, tired or
under the influence of alcohol or medication.
Always take timely breaks from your work.
Change your working position regularly.
Warning!
If the equipment is used for a lengthy period, the
vibrations it causes in the hands of the user may
result in circulation problems (white fi nger syn-
drome).
White fi nger syndrome is a vascular disease that
involves seizure-like spasms of the fi ngers and
toes. The aff ected areas are no longer suffi ciently
supplied with blood and therefore appear extre-
mely pale. The frequent use of vibrating equip-
ment may trigger nerve damage in people with
an impaired circulation (for example smokers,
diabetics).
Should you observe any unusual impairments,
interrupt your work immediately and consult a
doctor.
Follow these instructions in order to reduce the
dangers:
•
Keep your body and in particular your hands
warm when working in the cold.
•
Take regular breaks and move your hands
to stimulate the blood circulation during the
breaks.
•
Ensure that the equipment makes the least
possible vibration through regular mainte-
nance and solid parts on the equipment.
Additional safety instructions
We pay a great deal of attention to the design of
every battery pack to ensure that we supply you
with batteries which feature maximum power den-
sity, durability and safety. The battery cells have
a wide range of safety devices. Each individual
cell is initially formatted and its electrical charac-
teristic curves are recorded. These data are then
used exclusively to be able to assemble the best
possible battery packs. Despite all the safety
precautions, caution must always be exer-
cised when handling batteries. The following
points must be obeyed at all times to ensure
safe use.
Safe use can only be guaranteed if undama-
ged cells are used. Incorrect handling can
cause cell damage.
Important: Analyses confi rm that incorrect use
and poor care are the main causes of the damage
caused by high performance batteries.
Information about the battery
1. The battery pack supplied with your cordless
tool is not charged. The battery pack has to
be charged before you use the tool for the fi rst
time.
2. For optimum battery performance avoid low
discharge cycles. Charge the battery pack
frequently.
3. Store the battery pack in a cool place, ideally
at 15°C and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural
ageing process. The battery pack must be
replaced at the latest when its capacity falls to
just 80% of its capacity when new. Weakened
cells in an aged battery pack are no longer
capable of meeting the high power require-
ments and therefore pose a safety risk.
5. Do not throw battery packs into an open fi re.
There is a risk of explosion!
6. Do not ignite the battery pack or expose it to
fi re.
7. Do not exhaustively discharge batteries.
Exhaustive discharge will damage the battery
cells. The most common cause of exhaustive
discharge is lengthy storage or non-use of
partly discharged batteries. Stop working as
soon as the performance of the battery falls
noticeably or the electronic protection system
triggers. Place the battery pack in storage
only after it has been fully charged.
8. Protect batteries and the tool from over-
loads. Overloads will quickly result in over-
heating and cell damage inside the battery
housing without this overheating actually
being apparent externally.
9. Avoid damage and shocks. Replace batte-
ries which have been dropped from a height
of more than one meter or which have been
exposed to violent shocks without delay, even
if the housing of the battery pack appears to
be undamaged. The battery cells inside the
battery may have suff ered serious damage.
In this respect, please also read the waste
disposal information.
10. If the battery pack suff ers overloading and
overheating, the integrated protective cut-off
will switch off the equipment for safety rea-
