Festool TDK 15 - Manual (Page 13)

- By keeping the battery pack in a ready for use
charger, the battery pack will be kept in a state
of readiness by fl oat charging conservation.
- Do not keep discharged battery pack (maxi-
mum one month) attached to charger whene-
ver 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 ca-
pacity 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 lon-
ger periods should be stored in a discharged
state.
Special instructions for NiMH battery
packs:
- The output of NiMH battery packs drops no-
ticeably 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, re-
charge 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 auto-
matically, 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 perfor-
mance 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.
7 Recycling battery packs
Never throw spent battery packs
into domestic waste containers!
Return spent or defective battery packs to dea-
lers, the Festool after-sales service department
or approved waste disposal facilities. This en-
sures that they are correctly recycled.
