Festool TDK 12 Operating Instructions Manual - page 8
11
Do not use spent and recycled battery packs.
The user shall be liable for damages if Festool
original battery packs are not used.
- Keep the connection contacts of electronic
equipment, charger and battery pack clean.
- By keeping the battery pack in a ready for
use charger, the battery pack will be kept in
a state of readiness by float charging
conservation.
- Do not keep discharged battery pack
(maximum one month) attached to charger
whenever charger is detached from the
power supply (danger of deep discharging).
- A new battery pack or a battery pack not
used for a longer period of time reaches it
full capacity after about 5 charging and
discharging cycles.
- Battery packs should, before charging, be
fully discharged if possible.
Continuous starting of the charging process
shortens the lifespan of the batteries.
- A considerably reduced time of operation per
charging shows that the battery pack is used
up an should be replaced by a new one.
- NiCd battery packs that are not used for
longer periods should be stored in a
discharged state.
Special instructions for NiMH battery
packs:
- The output of NiMH battery packs drops
noticeably at ambient temperatures below
0° C or above 45° C.
- Do not overload the tool (do not load the
tool excessively so that it comes to a
standstill).
- Even if NiMH battery packs are not used,
recharge them approx. every 4 months so
that they retain their full capacity.
- NiMH battery packs should be left for 60 min.
in the charger after every 10th fast charge
to compensate any differences in capacity
between the cells.
- Because NiMH battery packs discharge
automatically, store them preferably at
ambient temperatures of between 0° C and
25° C.
6.1
Changing carbon brushes
If the carbon brushes have worn to a length of
less than 6 mm, this may reduce the
performance of the machine or cause the
machine to stop. In this case, the brushes (4.2)
should be replaced.
- Unscrew the cover (4.4) and remove the
worn brushes.
- Push in the retaining plate (4.3) on the new
carbon brushes until it latches into the notches
(4.1) and screw the covers back on.
- Operate the machine in idling state for a few
minutes so that the carbon brushes attain
optimal contact.

Recycling battery packs
Never throw spent battery packs
into domestic waste containers!
Return spent or defective battery packs to
dealers, the Festool after-sales service
department or approved waste disposal
facilities. This ensures that they are correctly
recycled.
