• Explanation of symbols on charger/battery
3 Read the instruction manual before use
4 Only use the charger indoors
5 Double insulation (no earth wire required)
6 Batteries may explode when disposed of in fi re,
so do not burn battery for any reason
7 Store tool/charger/battery in locations where
temperature will not exceed 50°C
8 Do not dispose of the charger together with
household waste material
9 Do not dispose of the battery together with
household waste material
WHEN CONNECTING NEW 3-PIN PLUG (U.K. ONLY):
• Do not connect the blue (= neutral) or brown (= live) wire
in the cord of the charger to the earth terminal of the
plug
• If for any reason the old plug is cut off the cord of the
charger, it must be disposed of safely and not left
unattended
USE
• Combined switch A 2 for on/off and speed control
Control the speed steplessly from zero to maximum by
putting less or more pressure on the trigger
• Charging battery 0
! a lithium-ion battery that is new or has not been
used for a longer period does not develop its full
capacity until after approximately 3 charging/
discharging cycles
- connect charger to power source as illustrated 0a
- green light B will turn on indicating that the charger is
ready for operation 0a
- insert battery into charger as illustrated 0b
- green light B will blink indicating that the battery is
receiving a charge 0c
- after approximately 1 hour the battery is fully charged
and green light B stays on after blinking, at which
time the charger automatically switches to
maintenance-charging 0d
! remove battery from charger after charging
period has ended thereby lengthening the service
life of the battery
IMPORTANT:
- if green light B starts blinking rapidly after inserting a
battery, this may mean:
1) that the battery is too cold or too hot (charger only
charges batteries when its temperature is between
0°C and 45°C); the charger then automatically
switches to maintenance-charging, until a
temperature between 0°C and 45°C is reached, at
which time the charger will automatically switch to
normal charging 0e
2) that the battery should be replaced 0f
- the lithium-ion battery can be charged at any time
(interrupting the charging procedure does not
damage the battery)
- the lithium-ion battery does not have to be empty
before charging (no "memory-effect" as with nickel-
cadmium batteries)
- while charging, the charger and the battery may
become warm to touch; this is normal and does not
indicate a problem
- ensure that the outside surface of the battery is clean
and dry before inserting into charger
- do not charge at temperatures below 0°C and over
45°C; this will seriously damage the battery as well
as the charger
- do not remove battery from tool while it is running
- if you anticipate long periods of non-use for the tool,
it is best to unplug the charger from its power source
- when the lithium-ion battery is empty, the tool is
switched off automatically
- a signifi cantly reduced working period after charging
indicates that the battery is worn out and should be
replaced
• Changing direction of rotation !
- when not properly set in left/right position,
switch A 2 cannot be activated
! change direction of rotation only when tool is at a
complete standstill
• Changing bits @
- insert the bit as deep as possible in the chuck
! do not use bits with a damaged shank
! only use sharp bits
• Torque control (VariTorque) #
- output torque will increase as clutch ring C is rotated
from 1 to 25; position D will lock up the clutch to
permit drilling or driving heavy duty work
- when turning in a screw, fi rst try VariTorque position 1
and increase until the desired depth has been
reached
• Mechanical gear selection $
- set selector F to desired speed
! actuate the gear selector while tool is running
slowly
HIGH POWER
- high torque
- for screwdriving and drilling large diameters
- for tapping thread
HIGH SPEED
- lower torque
- for drilling small diameters
• Battery level indicator G %
Shows how much energy the battery has left
• Battery protection
Switches off the tool automatically when
1) the load is too high
2) the battery temperature is not within the allowable
operating temperature range of 0 to 45°C
3) the lithium-ion battery is nearly empty (to protect
against deep discharge)
- in either case the 3 LED-lights of battery level
indicator G will fl ash rapidly
! do not continue to press the on/off switch after
the tool is switched off automatically; battery may
be damaged
• Automatic spindle-lock
- when switch A 2 is not pressed, the spindle is
locked
- allows you to use the tool as a screwdriver (even
when the battery is empty)
