ADJUSTING THE TORQUE
Fig. D
The appliance has 16 different torque settings with
which to set the power for driving and removing screws.
• Set the torque adjustment ring (3) to the desired
position.
The available torque settings are indicated on the
adjustment ring by the numbers 1 to 8 and by dots
between the figures to define intermediate settings
(16 in total).
• You should preferably choose as low a setting as
possible when using the screwdriver. Select a higher
setting if the motor slips.
DRIVING AND REMOVING SCREWS
• Set the direction reversing switch (2) to position 'R'
in order to drive screws.
• Set the direction reversing switch to position 'L' in
order to remove screws.
DRILLING
• Rotate the torque adjustment ring (3) to the drilling
position.
Ensure that the direction reversing switch (2) is
always set to 'R' during drilling.
SWITCHING THE DEVICE ON AND OF
Fig. A
• Depress the on/off switch (1). It regulates the speed
of the appliance by transmitting power to the switch.
• Release the on/off switch (1) to halt the drill chuck
immediately which will no longer run on.
• Move the direction reversing switch (2) to the centre
in order to lock the appliance in its disabled state.
Only lay down the appliance when it has stopped running
completely. Do not place it on a dusty surface as
particles of dust could get into the mechanism.
CHARGING THE BATTERY
Fig. E
The included battery is delivered in non-charged
condition.
• Only use the battery charger in a temperature range
between +10º to + 40º Celsius.
• Only use the battery charger in dry, ventilated
rooms.
CHARGING
• Place the battery holder on a flat table and put the
battery in the battery holder. Pay attention to + and -
pole markings.
• Put the adapter plug of the net adapter in the
connector on the side of the battery holder.
• Put the net adapter in the socket.
• The red charging lamp on the battery holder will
illuminate indicating the battery is being charged.
• The charging process of a fully discharged battery will
take approximately 5 hours the first time and
afterwards approximately 3 hours.
After the charging time the red light will not switch
off automatically! Remove the battery within 5
hours from the charger. If the battery is not
removed from the charger after the charging
period it may become overheated.
DISCHARGING THE BATTEY
Not only charging batteries is important,
discharging is of equal importance or even greater
importance.
• When the battery is charged the cordless drill has to
be used until you start noticing that the power of the
drill is diminishing and that the maximum rotational
speed is not reached.
• The battery is almost discharged now. Only now you
can start charging the battery.
• Charging the battery while it is still charged for say
one-third of capacity, the so-called ‘memory effect’
can occur. Since during charging only the discharged
part of the battery capacity of the battery is being
charged now, the battery can start crystallizing in the
one-third that is still charged. This part of the battery
capacity can never be used afterwards.
• Do not discharge the battery to the minimum. As
soon as you notice that the power or the maximum
rotational speed is diminishing, you have to charge
the battery. When you proceed using the drill and
the battery becomes fully discharged, the so-called
‘switch of poles effect’ can occur. The polarity of the
battery poles will be switched: the ‘+’will become ‘-‘
and the ‘-‘ will become the ‘+’. Once this has
occurred the polarity will remain switched during
loading and this will damage the battery irreparable.
When the cordless drill is not being used over a
longer period of time, the battery has to be charged
fully first. The battery has to be stored in charged
condition.
MAINTENANCE
These appliances are designed to function without
difficulty for a long time and to require minimum
maintenance. You will prolong the appliance's life by
cleaning it regularly and using it correctly.
CLEANING
Clean the housing regularly with a soft cloth, preferably
every time it is used. Keep the air vents free of dust and
dirt. Remove stubborn dirt with a soft rag moistened in
soapy water. Do not use any solvents such as petrol,
alcohol, ammonia, etc. as such substances can damage
the plastic parts.
LUBRICATION
The appliance does not need any extra lubrication.
FAULTS
Should a fault occur, e.g. after wear of a part, please
contact the service address on the warranty card. In the
back of this manual you find an exploded view showing
the parts that can be ordered.
