Use
Warning! Let the tool work at its own pace. Do not overload.
Warning! Before drilling into walls, floors or ceilings, check for
the location of wiring and pipes.
Charging the battery (fig. C)
The battery needs to be charged before first use and whenev-
er it fails to produce sufficient power on jobs that were easily
done before. The battery may become warm while charging;
this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures
below 10 °C or above 40 °C. Recommended charging tem-
perature: approx. 24 °C.
Note: The charger will not charge a battery if the cell
temperature is below approximately 10 °C or above 40 °C.
The battery should be left in the charger and the charger
will begin to charge automatically when the cell tempera-
ture warms up or cools down.
To charge the battery (5), insert it into the charger (11).
u
The battery will only fit into the charger in one way. Do
not force. Be sure that the battery is fully seated in the
charger.
Plug in the charger and switch on at the mains.
u
The charging indicator (12) will blink.
The charge is complete when the charging indicator (12)
switches to continuously on. The charger and the battery can
be left connected indefinitely. The LED will switch on as the
charger occasionally tops up the battery charge.
Charge discharged batteries within 1 week. Battery life will
u
be greatly diminished if stored in a discharged state.
Leaving the battery in the charger
The charger and battery pack can be left connected with the
LED glowing indefinitely. The charger will keep the battery
pack fresh and fully charged.
Charger diagnostics
If the charger detects a weak or damaged battery, the charg-
ing indicator (12) will flash red at a fast rate. Proceed as
follows:
Re-insert the battery (5).
u
If the charging indicators continues flashing red at a fast
u
rate, use a different battery to determine if the charging
process works properly.
If the replaced battery charges correctly, the original
u
battery is defective and should be returned to a service
centre for recycling.
If the new battery gives the same indication as the original
u
battery, take the charger to be tested at an authorised
services centre.
