9 Accumulator Charging Instructions
1. Please make sure the mains voltage is the same as the voltage
listed on the charger's machine plate. Connect the charger [N1] to
a power source. A red LED indicator [N2] will light up. This means
the charger is ready to charge. If the red LED indicator does not
light up, check the connection to power supply. If the power
supply functioning correctly, bring the charger in for repair to an
authorised service centre!
2. Slide the accumulator [B1] all the way into the charger.
3. The red LED will light up and the green LED [N2] will start flashing
to indicate that the accumulator is charging.
4. After approximately 60 minutes, the accumulator should be fully
charged, indicated by the green and red LED staying lit without
flashing.
5. Remove the accumulator from the charger. If you do not wish to
charge another accumulator, disconnect the charger from the
power source.

9.1 New batteries:
Battery capacity may be slightly smaller than the listed value during
the first few initial charge cycles. The reason is that the chemical com‑
position of the batteries has not been activated yet. This is a temporary
issue and will resolve on its own after a few charge cycles.
Note:
• A blinking green indicator means that the battery is fully charged
or that it is in slow charge mode, which maintains a low charge
level of the battery.
• The initial battery charge may take longer then 60 minutes (ac‑
cording to battery capacity) depending on the environment tem‑
perature, the power supply and the current charge level.
• If you are not using the charger, please unplug it from the power
source.
9.2 Important information about the
charging process:
1. To get the best out of the batteries in terms of longevity and per‑
formance is to charge them at an ambient temperature of 18 °C
to 24 °C. DO NOT CHARGE the batteries at temperatures below
0 °C and above 45 °C. This is very important. You will prevent seri‑
ous battery damage.
• Do not charge the batteries in direct sunlight, especially in the
summer! You will prevent extreme overheating, which could
damage them!
2. If a battery that is too cold (below 0 °C) is inserted into the charg‑
er, the charger will not begin charging it right away; instead, the
green and the red indicator light will begin blinking. Once the bat‑
tery reaches the right temperature naturally (within the standard
range), the fast charge process will begin automatically.
• If an accumulator that is too hot (over 45°C) is placed in the charg‑
er, the charger will not begin charging right away; instead, the red
indicator will start flashing. Once the accumulator temperature
drops to within the standard range, the quick charging process
will begin automatically.
3. If the accumulators cannot be charged properly (the green and
red indicators are alternating):
• Check that the battery contact surfaces are not dirty. Clean them
with a cotton wad and alcohol as needed.
• If the battery is still not charging properly, send or bring the

charger (including the batteries) to your nearest authorised ser‑
vice centre.
4. Under certain conditions and if the charger is connected to power,
foreign material may short circuit the charge contacts inside the
charger. Foreign conducting substances, such as steel fibres, alu‑
minium foils or metal deposits must be removed from the charger
continuously. Always unplug the charger from power prior to
cleaning.
5. If you are carrying out several different charge operations one af‑
ter the other, the charger may become hot. This is normal and is
not a sign of a technical problem.
6. Prevent liquid from getting inside the charger as it could cause an
electrical injury. Do not place the battery in a hot environment if
you wish to facilitate the battery cool down process.
7. Accumulator batteries can remain plugged into the charger with‑
out a risk of damage to them or the charger itself. The batteries will
remain fully charged in the charger. DO NOT LEAVE charged batter‑
ies in the charger if the charger is not plugged into the power outlet.
8. DO NOT USE ACCUMULATOR BATTERIES if they are damaged
or if liquid leaks out of the cells. If the battery liquid comes into
contact with your skin, immediately flush the area with water and
monitor the skin's reaction. Seek medical attention if needed. If it
comes into contact with your eyes, flush them with lots of water
and immediately seek medical attention.
9. If you are charging a fully discharged battery or if you stop charg‑
ing the battery before it is fully charged, you must count each of
these cycles as an entire charging cycle.
9.3 Note on Lithium-ion (Li-Ion) batteries
• These types of batteries do not have a memory effect, in other
words, the batteries can be charged at any state of discharge. If
you take the batteries out of the charger prior to fully charging
them, it will not damage them.
• Each Li‑Ion battery is equipped with deep discharge protection.
If the voltage falls (due to overloading or discharge) below the
monitored range, the electronic circuit will disconnect the cells.
The machine will then either work intermittently or not at all. You
must reduce machine load or recharge the battery.
9.4 Storing lithium-ion batteries
• Store fully charge batteries in a dry and dust‑free environment at
an ambient temperature between 5 °C and 40 °C. If you are not
using the batteries for a longer period of time, we recommend
you charge them fully once every three months.
• Keep the battery contacts clean. Do not store the replacement
battery together with metal items as it may cause a short circuit.
• It is always necessary to charge batteries that were not used for
a long time prior to use.
9.5 Transporting lithium-ion batteries
As per legal regulation, lithium‑ion batteries fall into the hazardous
load category. These batteries must be transported while complying
with local, national, as well as international guidelines and regulations.
• Consumers may transport these batteries on public roads without
a problem.
• Commercial transportation of lithium‑ion batteries by transporta‑
tion companies must comply with the regulation on hazardous
load transportation. Only trained personnel may carry out the
preparation and the actual transport. The entire process must
have expert supervision.
The following must be maintained during battery transportation:
• Make sure that contacts are protected and isolated to prevent
a short circuit.
• Be careful so that a large number of batteries do not move around
or fall and collapse during transport.
• Damaged and leaking batteries cannot be transported.
Please contact your carrier for additional information.
Warning!!
It is not expected for the user to perform any service repairs on the
charger. There are no spare parts inside the charger, which users could
repair on their own. It is necessary to bring the charger to your nearest
