5. If any wires on the charger are damaged, do not use it
until these have been replaced.
6. When the charger is not in use it should not be
plugged in. When unplugging, do not pull the plug out
by the cable.
7. If the charger breaks down or suffers from other
technical problems, take it to a recognised dealership
to be checked before using it again. Any damaged
parts must be replaced.
8. Take care when handling the accumulator block, do
not drop it or knock it against other things.
9. Never attempt to repair the battery charger or
accumulator block yourself; this can be extremely
dangerous. Repairs should always be carried out by a
recognised dealership.
10. Always unplug the charger before cleaning or
carrying out any other maintenance on it.
11. Do not attempt to charge the accumulator block in
temperatures of below 10 degrees or above 40
degrees centigrade.
12. The accumulator block must not be short-circuited.
When an apparatus short-circuits, the strength of
the electric current is increased. This can cause the
apparatus to over heat, catch fire or even explode, causing
damage and also endangering the operator.
To avoid this;
• Firstly do not connect any wires to the poles of the
accumulator block;
• Ensure that no metal objects (nails, coins, paper-clips)
are caught in the opening of the accumulator block;
• do not expose the accumulator block to water or rain.
13. If the accumulator block is broken or can no longer
be recharged it must be properly disposed off.
14. Never throw the accumulator block into water or a
fire – it may explode.
15. When drilling or screwing in walls, floors, etc.,
electricity lines can be hit. Hold the tool at the plastic
handle to prevent an electrical shock. Never hold the
tool at the chuck or another metal part.
16. Turn the drill immediately off after the screw is
fastened. Overloading and damaging the battery or
motor can be prevented this way. Use the torque to
loosen the fastened screw.
MOUNTING ACCESSORIES
INSERTING AND REMOVING BITS
Fig. C & D
When the ring is mounted, bits can easily be placed into
the hexagonal drive shaft:
• The bits can be placed directly on the tool, or on the
extension piece
• The sockets can be placed with help of the small
adapter piece (square-hexagonal)
Replace the ring by the keyless chuck, for using small
drills (max 6mm).
INSERTING AND REMOVING THE BATTERY
Fig. B
• Place the battery (6) at the bottom of the tool, as
shown in the figure. Ferm the battery until it snaps
into place.
• Ferm the release buttons (5) to remove the battery
from the bottom of the tool.
THE BATTERY LIFE SPAN
The battery life span is limited. If the run time of a loaded
battery shortens considerably, a new battery must be
purchased. If the tool is used irregularly, then charge the
battery at least once every six months for an optimal
result. When the battery is used under extreme hot or
cold circumstances the capacity will be less per charge.
OPERATION
Always observe the safety instructions and appli-
cable regulations.
Firmly hold the machine and ferm the bit with even
pressure into the workpiece. Do not force the machine.
Use only bits that do not yet show any signs of wear.
Worn bits have a negative effect on the efficiency of the
machine.
TORQUE ADJUSTMENT
Fig. E
The machine has different torque settings by means of
which the force for fastening and loosening screws can
be determined.
• Put the torque setting ring (2) at the required torque.
• Preferably select the lowest possible setting to move
the screw. Select a higher torque setting when the
motor is slipping.
• If the battery gets discharged, the motor will not slip
in position 4 or 5. Recharge the battery.
FASTENING AND LOOSENING SCREWS
• Ferm the top half of the direction switch (Fig. A. 3)
down to fasten screws (R).
• Ferm the lower half of the direction switch (Fig. A. 3)
up to loosen screws (L).
CHARGING BATTERIES
The battery that comes with the machine is not
fully charged.
• Only use the battery charger at temperatures
between +10 and +40 °Celsius.
• Only use the battery charger in dry rooms.
CHARGING
• Remove the battery from the machine
• Ferm the adapter plug of the charger into the battery
(near red LED)
• Plug the mains adapter into the (wall) socket
• The charging process starts; the red LED is now on
• If the battery is completely discharged or not used
for a long period, it takes about 24 hours to charge
the battery. Normally it takes about 5 hours.
• Place the battery in the tool after charging.
