Using an extension cable
An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for the
power input of your charger (see technical data). The minimum
conductor size is 1 mm2; the maximum length is 30 m.

Assembly and adjustment

• Prior to assembly and adjustment, always
remove the battery pack.
• Always switch off the tool before inserting
or removing the battery pack.
Use only Berner battery packs and
chargers.
Battery pack (fi g. A & B)
Charging the battery pack (fi g. A)
When charging the battery pack for the fi rst time, or after
prolonged storage, it will only accept an 80% charge. After
several charge and discharge cycles, the battery pack will
attain full capacity.
Always check the mains prior to charging the battery pack.
If the mains is functioning but the battery pack does not
charge, take your charger to an authorised Berner repair
agent. 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 (10), insert it into the
charger (12) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (13) will blink.
After approx. 1 hour, it will stop blinking and remain
on. The battery pack is now fully charged. The
battery pack can be removed at any time or left in the
connected charger for a longer period of time (with a
maximum of 14 days).
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
(11) simultaneously and pull the pack out of the grip.
Battery cap (fi g. B)
A protective cap is supplied to cover the contacts of
a detached battery pack. Without the protective cap in
place, loose metal objects could short circuit the contacts,
causing a fi re hazard and damaging the battery pack.
• Take off the protective cap (14) before placing the
battery pack (10) in the charger or tool.
• Place the protective cap over the contacts immediately
after removing the battery pack from the charger or tool.
Make sure the protective cap is in place
before storing or carrying a detached
battery pack.
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/Cold Pack Delay
When the charger detects a battery that is too hot or
too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
maximum battery life. The red indicator blinks long, then
short while in the Hot/Cold Pack Delay mode.
Selecting the operating mode (fi g. C1)
BACHD-18V (fi g. C1)
The tool can be used in the following operating modes:
Rotary drilling: for screwdriving and for
drilling into steel, wood and plastics
Hammer drilling: for concrete and masonry
drilling.
• To select the operating mode, press the safety lock
(4) and rotate the mode selector switch (3) until it
points to the symbol of the required mode.
• Release the safety lock and check that the mode
selector switch is locked in place.
Do not select the operating mode when the
tool is running.
Inserting and removing SDS-plus accessories (fi g. D)
Your rotary hammer drill uses SDS-plus accessories (refer
to the inset in fi g. D for a cross-section of an SDS-plus
bit shank).
• Clean and grease the bit shank.
• Insert the bit shank into the tool holder (5).
• Push the bit down and turn it slightly until it fi ts 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 (15) and pull out the bit.
