EXPLANATION OF SYMBOLS ON TOOL/BATTERY
3 Read the instruction manual before use
4 Batteries may explode when disposed of in fire, so do not
burn battery for any reason
5 Store tool/charger/battery in locations where temperature
will not exceed 50°C
6 Do not dispose of electric tools and batteries together
with household waste material
USE
• Combined switch for on/off and speed control A 2 8 9
- control the speed steplessly from zero to maximum by
putting less or more pressure on the trigger
• Charging battery
! read the safety warnings and instructions
provided with the charger
• Removing/installing the battery 2
• Battery level indicator 7
- press the battery level indicator button H to show the
current battery level.
• Changing direction of rotation q
- when not properly set in left/right position, switch A
cannot be activated
! change direction of rotation only when tool is at a
complete standstill
• Changing bits w
! clean and lightly lubricate the SDS+ accessory
before insertion
- pull back locking sleeve C and insert accessory
in SDS+ chuck while turning and pushing it until it
engages; the accessory locks in position automatically
- pull accessory to check that it is locked correctly
- remove accessory by pulling back locking sleeve C
! the SDS+ accessory requires freedom of
movement which causes eccentricity when tool
is off-load; however, the accessory automatically
centres itself during operation without affecting
drilling precision
! when using hex bits, make sure that these hex bits
are at least 75 mm long, or otherwise use shorter
hex bits with hex adapter G
! do not use bits with a damaged shank
• Selecting operating mode e
1 = normal drilling/screwdriving
2 = hammer drilling
! select operating mode only when tool is switched
off and the switch is locked
- the hammer mechanism is activated by applying a
slight pressure on the tool when the drill bit is in contact
with the workpiece
- it takes a short time for the hammer mechanism to
reach full impact power
- best hammer drilling results can be obtained by only a
slight pressure on the tool; drilling performance will not
improve by applying more pressure on the tool
• Battery protection
Switches off the tool or prevents the tool from being
switched on, when
- the load is too high
- the battery temperature is not within the allowable
operating temperature range of -20 to +50°C
- the lithium-ion battery is nearly empty (to protect
against deep discharge)
! do not continue to press the on/off switch after the
tool is switched off automatically; battery may be
damaged
• LED-light E r
- LED-light E automatically lights on when activating
switch A 2
• Holding and guiding the tool t
! while working, always hold the tool at the grey-
coloured grip area(s)
- keep ventilation slots F 2 uncovered
- do not apply too much pressure on the tool; let the tool
do the work for you
APPLICATION ADVICE
Use the appropriate bits y
•
! only use sharp bits
• For drilling with non SDS drill bits in wood, metal and
plastic, use an adapter (not standard included) u
! clean and lightly lubricate the SDS+ accessory
before insertion
- pull back locking sleeve C 2 and insert adapter
in SDS+ chuck while turning and pushing it until it
engages; the adapter locks in position automatically
- pull adapter to check whether is it locked correctly
- set switch D 2 to normal drilling (only activate when
tool is switched off and the switch is locked)
• When drilling ferrous metals
- pre-drill a smaller hole, when a large hole is required
- lubricate drill bit occasionally with oil
• When turning in a screw at/near the cross cut end or an
edge of wood, pre-drill a hole in order to avoid cracking
of the wood
• Splinterfree drilling in wood i
Dustfree drilling in walls o
