Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one’s
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
u
Avoid dust accumulation at the workplace.
Dust can
easily ignite.
Operation
Starting Operation
u
Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
u
Products that are only sold in AUS and NZ:
Use a resid-
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Setting the rotational direction (see figure G)
u
Only operate the rotational direction switch (3) when
the power tool is not in use.
The rotational direction switch
(3)
is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch
(6)
is being pressed.
Clockwise rotation:
To drill and drive in screws, slide the
rotational direction switch
(3)
downwards on the left-hand
side and upwards on the right-hand side at the same time.
Anti-clockwise rotation:
To loosen and unscrew screws and
nuts, slide the rotational direction switch
(3)
upwards on the
left-hand side and downwards on the right-hand side at the
same time.
Setting the Operating Mode
Drilling and screwdriving
Set the selector switch
(2)
to the "drilling"
symbol.
Impact drilling
Set the selector switch
(2)
to the "impact
drilling" symbol.
The selector switch
(2)
clicks into place and
can also be actuated when the motor is running.
Mechanical Gear Selection
u
You can press the gear selector switch
(7)
with the
power tool running at a low speed. You should not do
this at full load or maximum torque, or when the tool is
not in use, however.
You can preselect two speed ranges with the gear selector
(7)
.
First gear:
Low speed range; for working with a large
drilling diameter or for screwdriving.
Second gear:
High speed range; for working with a small
drilling diameter.
If the gear selector
(7)
cannot be swivelled all the way to the
stop, turn the drive spindle slightly with the drill.
Switching on/off
To
start
the power tool, press and hold the on/off switch
(6)
.
Press the lock-on button
(4)
to
lock
the on/off switch
(6)
in
this position.
To
switch off
the power tool, release the on/off switch
(6)
;
or, if the switch is locked with the lock-on button
(4)
, briefly
press the on/off switch
(6)
and then release it.
Rapid Shut-off (KickBack control)
The rapid shut-off function (KickBack Con-
trol) gives the user greater control over the
power tool and offers them better protec-
tion than power tools that do not have Kick-
Back Control. The power tool will switch off if it suddenly
and unforeseeably rotates around the drilling axis.
To
switch the tool back on
, release the on/off switch and
then press it again twice.
u
It will no longer be possible to switch the power tool
on if the KickBack Control function is faulty. Have the
power tool serviced by a qualified repair person using
only original replacement parts.
Overload clutch
The power tool is equipped with an overload
clutch (anti-rotation) to limit high torque reac-
tions.
u
If the application tool jams or snags, the power trans-
mission to the drill spindle will be interrupted. Always
hold the power tool firmly with both hands to with-
stand the forces this may create and adopt a position
with stable footing.
u
Switch the power tool off immediately and remove the
application tool if the power tool becomes blocked.
Switching on when the drilling tool is blocked may
cause high torque reactions.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch
(6)
to varying ex-
tents.
Applying light pressure to the on/off switch
(6)
results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
