DeWalt DW999 Bedienungsanleitung Seite 25

Whilst charging, the charger and the battery pack may
become warm to touch. This is a normal condition and
does not indicate a problem.
Do not charge the battery pack at
ambient temperatures < 4 °C or > 40 °C.
Recommended charging temperature:
approx. 24 °C.
• To charge the battery pack (9), insert it into the
charger (11) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (12) will blink.
After approx. 1 hour, it will stop blinking and
remain on. The battery pack is now fully charged
and the charger automatically switches to
equalise mode. After approx. 4 hours, it will
switch to maintenance charge mode. The battery
pack can be removed at any time or left in the
connected charger indefinitely.
• The red charging indicator flashes rapidly to
indicate a charging problem. Reinsert the battery
pack or try a new one. If the new pack also
refuses to charge, have your charger tested by
an authorized D WALT repair agent.

• When plugged into power sources such as
generators or sources that convert DC to AC,
the red charging indicator may blink twice,
switch off and repeat. This indicates a temporary
problem of the power source. The charger will
automatically switch back to normal operation.
Inserting and removing the battery pack
• Insert the battery pack into the grip until it clicks
in place.
• To remove the battery pack, press the two
release buttons (10) simultaneously and pull the
pack out of the grip.
Equalization mode
The equalization mode helps to
maintain the optimum capacity of the
battery pack. It is therefore
recommended to use the equalization
mode weekly or every 10 charge/
discharge cycles.

• Charge the battery pack as described above.
• When the charging indicator stops blinking, leave
the battery in the charger for approx. 4 hours.
Hot Pack Delay
When the charger detects a battery that is hot, it
automatically starts a Hot Pack Delay, suspending
charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the
pack charging mode. This feature ensures maximum
battery life. The red indicator (12) blinks long, then
short while in the Hot Pack Delay mode.
Selecting the operating mode (fig. B)
The rotary hammer drill can be used in two
operating modes:
• Select the required operating mode by rotating
the mode selector (3) towards the symbol on the
gear housing.
• For screwdriving, refer to section «Instructions for
use».
Inserting and removing SDS-plus accessories
(fig. C)
Your rotary hammer drill uses SDS-plus accessories
(refer to the inset in fig. C for a cross-section of an
SDS-plus bit shank).
• Clean and grease the bit shank.
• Insert the bit shank into the tool holder (7).
• Push the bit down and turn it slightly until it fits
into the slots.
• Pull on the bit to check if it is properly locked.
The hammering function requires the bit to be
able to move axially several centimetres when
locked in the tool holder.
• To remove a bit pull back the tool holder locking
sleeve (7) and pull out the bit.
