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 (8) 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 (8).
Equalization mode
The equalization mode helps to maintain the
optimum capacity of the battery pack. It is therefore
recommended to use the equalization mode monthly
or every 20 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.
DE9108/DE9116 - 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.

a complete standstill before changing the
direction of rotation.
Two gear selector (fig. E)
Your tool is fitted with a two gear selector (6) to vary
the speed/torque ratio.

(drilling large holes, driving screws)
2 high speed/low torque (drilling smaller holes)
For speed rates, refer to the technical data.
