Before Putting into Operation

Battery Charging
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approximately 5 charging/discharging
cycles.
To remove the battery 6, press the unlocking but-
tons 8 and pull out the battery downwards. Do not
exert any force.
The battery is equipped with an NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C.
A long battery service life is achieved in this man-
ner.
A significantly reduced working period after
charging indicates that the batteries are used and
must be replaced.
Observe the notes on environmental protec-
tion.
Auxiliary Handle (see figure
(GSB 12 – 24 VE-2/
GSR 18 – 24 VE-2)
Loosen the handle by turning to the left. Rotate
the auxiliary handle 9 and adapt to the working
position. Make sure that the clamping band 11 of
the auxiliary handle remains in the groove.
Afterwards tighten the handle again by turn-
ing in clockwise direction.

Changing the Tool

Open the drill chuck until the tool can be inserted.
Insert the tool.
Firmly tighten the sleeve of the keyless chuck 3
by hand until the locking action ("click") is no
longer heard. This automatically locks the chuck.
Rotate the sleeve in the reverse direction to re-
move the tool.
Screwdriving (see figure
Clamp the bit 12 directly into the drill chuck. For
quick changes, using the universal bit holder 7 is
recommended.

Inserting the Battery
Set the rotational direction switch 5 to the centre
position = lock-off and allow the charged bat-
tery 6 to engage into the handle.
Switching On and Off
To start the machine, press the On/Off switch 4
and keep it depressed.
To switch off the machine, release the On/Off
switch 4.
)
A Electric Brake
When releasing the On/Off switch 4 the speed of
the drill chuck is reduced to a stop, thus prevent-
ing the run-on of the tool.
For screwdriving applications, wait until the screw
is flush with the material and then release the On/
Off switch 4. The screw head does not penetrate
into the material then.
Gear Selection, Mechanical
Two speed ranges can be preselected with the
gear selector 1:
1st gear:
2nd gear:
The gear setting can be changed while the ma-
chine is running, however, not while under load.
It is recommended to carry out the switching
while the machine is at a standstill. If the gear se-
lector 1 cannot be slid into the end position while
the machine is at a standstill, turn the chuck
somewhat or briefly press the On/Off switch 4.

Initial Operation

The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 4. Light pres-
sure results in a low rotational
speed thus allowing smooth, con-
trolled starts. Do not strain the ma-
chine so heavily that it comes to a
standstill.
Low rotational speed, high power.
High rotational speed, less power.
