recharged when partly discharged (memory
effect).
Maintenance cycle: To discharge the battery, allow the
tool to run without load until the performance clearly
falls. Then wait 5 – 10 minutes before starting the
charging process to recharge the cells fully.
Battery care
Ni-Cd batteries
If you only use the tool every 1 – 2 months, you
n
must ensure that the battery is discharged every
time before you charge it (see above).
If you use the tool less than every 1 – 2 months,
n
carry out the maintenance cycle (see above)
every 1 – 2 months.
If you use the tool several times per month, the
n
battery does not have to be discharged every
time before you charge it – all you have to do is
charge it. The battery pack must be completely
discharged and then recharged every 1 – 2
months.
Ni-Mh batteries
Ni-Mh batteries have less tendency to form a
n
memory effect. If you only use the tool every 2 – 3
months, we nevertheless recommend that you
discharge the battery every time before you
charge it (see above).
If you use the tool less than every 2 – 3 months,
n
carry out the maintenance cycle (see above)
every 2 – 3 months.
If you use the tool several times a month you will
n
avoid low discharge cycles. If you only discharge
your battery to max. 80%, you should recharge
the batteries more frequently. A maintenance
cycle involving a full discharge and charge cycle
is required every 2 – 3 months.
Incorrect or no battery care will result in the
crystallization of the active materials (memory effect)
and it should be noted that loss of performance or
defects caused by a lack of battery care are expressly
excluded from the warranty.
1. Never use batteries which have been damaged
by memory effects. Crystallites which have
formed may puncture the internal separator and
cause internal short circuits during
charge/discharging or if they are subjected to
mechanical stresses (vibrations, gentle shocks,
etc.). There is a risk of explosion!
2. Batteries are subject to a natural ageing process
(dependent on time and the number of cycles).
The battery 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
requirements and therefore pose a safety risk.
3. Do not throw battery packs into an open fire.
There is a risk of explosion!
4. Do not ignite the battery pack or expose it to fire.
5. 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. End the process as soon as
the performance of the battery falls noticeably.
Only place the battery in storage after it has been
fully charged.
6. Protect batteries and the tool from overloads.
Overloads will quickly result in overheating and
cell damage inside the battery housing without
this overheating actually being apparent
externally.
7. Avoid damage and shocks. Replace batteries
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
suffered serious damage. In this respect, please
also read the waste disposal information.
Information on chargers and the charging
process
1. Please check the data marked on the rating plate
of the battery charger. Be sure to connect the
battery charger to a power supply with the voltage
marked on the rating plate. Never connect it to a
different mains voltage.
2. Protect the battery charger and its cable from
damage and sharp edges. Have damaged cables
repaired without delay by a qualified electrician.
3. Keep the battery charger, batteries and the
cordless tool out of children's reach.
4. Do not use damaged battery chargers.
5. Do not use the supplied battery charger to charge
other cordless tools.
6. In heavy use the battery pack will become warm.
Allow the battery pack to cool to room
temperature before commencing with the
charging.
7. Do not over-charge batteries. Do not exceed
the maximum charging times. These charging
times only apply to discharged batteries. Frequent
insertion of a charged or partly charged battery
(Ni-Mh batteries with a charge of more than 20%)
will result in over-charging and cell damage. Do
not leave batteries in the charger for days on end.
8. Never use or charge batteries if you suspect
that the last time they were charged was
more than 12 months previously. There is a
