* After the charger is connected to the power supply, the green and red LEDs will
blink alternatively (in turn) for ca 1 s and then the red LED will go on continuously.
New accumulators:
During the first cycles of charging capacity of the new accumula-
tor can be lower than the rated value, namely due to the fact that
chemical accumulator composition has not been activated yet.
This state is of temporary nature and will be compensated after
a few cycles of charging.
Note:
• The steady green light indicates that the battery pack is fully
charged or in slow charging mode to maintain battery pack
charge level.
• Depending on the ambient temperature, line voltage and ex-
isting charge level, the initial battery charging may take longer
than 25–45 minutes (depending on battery pack type).
• Disconnect charger from power source when not in use.
Important notes for charging:
1. The longest service life and the best capacity can be reached
if the accumulators are charged at the ambient temperature
ranging from 18 °C to 24 °C.
DO NOT RECHARGE
the accumu-
lators at the temperature below 0 °C or over 45 °C. This is very
important. You can thus prevent serious accumulator damage.
• In summer months do not recharge the accumulators at direct
sunlight! You can thus prevent their enormous heating which
could result in their damage!
2. The charger is equipped by the AFCS system (Air-Forced Cool-
ing System) facilitating quick accumulator charging/recharg-
ing. This is possible only if the internal accumulator tempera-
ture ranges from 0 °C to 45 °C.
• if the battery pack just inserted into the charger is too cold
(below 0 °C), the charger will not recharge it immediately and
only the green and red pilot lamp will blink alternatively. After
the battery pack temperature fits the standard temperature
range by a natural method, the fast recharging procedure will
be started automatically.
• if the battery pack just inserted into the charger is too hot
(over 45 °C), ), the charger will not recharge it immediately and
only the green and red pilot lamp will blink alternatively. At
the same time the fan inside the charger will be started and
through its vent holes (11) the colder air will be circulated in-
side the heated battery pack. After the battery pack tempera-
ture fits the standard temperature range, the fast recharging
procedure will be started automatically.
• The AFCS system is started automatically during each recharg-
ing and prevents overheating of both the battery pack and the
charger.
3. If the accumulators cannot be charged duly (the red pilot lamp
is on intermittently):
• Check accumulator contact areas for possible pollution.
Clean them by a cotton swab and spirit, if necessary.
• If the accumulators still cannot be charged correctly, send
or hand over the charger (incl. the accumulators) to the
nearest authorized service centre.
4. Under certain conditions, with the charger plugged into the
power source, the exposed charging contacts inside the charg-
er can be shorted by foreign material. Foreign materials of
a conductive nature such as, but not limited to, steel wool, alu-
minum foil, or any buildup of metallic particles should be kept
away from charger cavities. Unplug charger before attempting
to clean.
5. If several charging operations are performed consecutively,
the charger can become warm. It is normal and does not indi-
cate any technical defect.
6. Prevent leak of liquid into the charger to avoid electrical acci-
dent. If you want to facilitate accumulator cooling after its use,
do not place it in a warm(ed) environment.
7. The accumulators can remain placed in the switched-on
charger without any damage to themselves or to the charg-
er. The accumulators remain in the fully charged state in the
charger.
DO NOT LET
the charged accumulators in the charger
disconnected from the power supply.
8.
DO NOT USE THE BATTERY PACK
if it is damaged and liquid is
leaked from the battery pack cells. If this leakage gets on your
skin, please wash the affected part immediately and observe
possible skin reaction. If necessary, please seek medical atten-
tion.
9. If you charge the not yet fully discharged accumulator or if you
terminate accumulator charging before the fully charged state
is reached, each such cycle has to be considered one complete
cycle of charging.
Notes for lithium (Li-Ion) accumulators
• This battery pack type does not suffer form the memory effect,
it means that the accumulators can be charged in any state
of charging. If you remove the battery pack from the battery
compartment before the battery is fully charged, it will not
cause any damage to the battery.
•
Charge the accumulators in the universal charger AN-
UNI, order No.: 00648648 only. Charging in older charger
types, having unsuitable characteristics of charging for
the Li-Ion accumulators, can result in irreversible accumu-
lator damage!
• The Li-Ion accumulator is equipped by protection from deep
discharge. If the voltage drops below the preset limit (by
overload or discharge), the electronic system disconnects the
accumulators. The device then works intermittently or does
not work at all. It is necessary to reduce machine load or to
recharge the accumulator.
Accumulator storage
Store the accumulators in the fully charged state in a dry and dust-
free room at the ambient temperature ranging preferably from
5 °C to 40 °C. If you do not use the accumulators for a longer time
period, it is recommended to charge the accumulators fully once in
three months as a minimum!
Warning!!
The charger is not user serviceable. There are no user serviceable
parts inside the charger. Servicing at the closest Authorized Ser-
vice Center is required to avoid damage to static sensitive internal
components.
Always use correct battery pack (pack supplied with the tool or the
replacement pack recommended by the manufacturer, the compa-
ny Narex s.r.o.) Never install another battery pack type. It will ruin
your tool and may create a hazardous condition.
