Firmly tighten the collar of the keyless chuck 2 by hand in ro-
tation direction . This automatically locks the drill chuck.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health and cause allergic reactions, lead to res-
piratory infections and/or cancer. 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
materials to be worked.
Prevent dust accumulation at the workplace. Dust can
easily ignite.
Operation
Starting Operation
Inserting the battery
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Set the rotational direction switch 13 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 8 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the rotational direction (see figure B)
The rotational direction switch 13 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 14 actuated.
Rotate clockwise: Move the rotational direction switch
13 on both sides up to the stop into position .
Rotate anticlockwise: Move the rotational direction
switch 13 on both sides up to the stop into position .
Setting the operating mode
Drilling
GSR 14,4 V-EC, GSR 18 V-EC:
Set the torque selector setting ring 3 to the re-
quired torque.
GSB 14,4 V-EC, GSB 18 V-EC:
Set the operating mode selector switch 4 to the
“drilling” symbol.
Screwdriving
GSR 14,4 V-EC, GSR 18 V-EC:
Set the torque selector setting ring 3 to the
“screwdriving” symbol.
GSB 14,4 V-EC, GSB 18 V-EC:
Set the operating mode selector switch 4 to the
“screwdriving” symbol.
Impact drilling(GSB 14,4 V-EC, GSB 18 V-EC)
Set the operating mode selector switch 4 to the
“impact drilling” symbol.
Switching On and Off
To start the machine, press the On/Off switch 14 and keep it
pressed.
The LED 10 lights up when the On/Off switch 14 is halfway or
fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 14 is
pressed.
Light pressure on the On/Off switch 14 results in a low rota-
tional speed. Further pressure on the switch results in an in-
crease in speed.
Setting the torque
With the torque preselection ring 3, the required torque can
be preselected in 20 steps. The inserted tool is stopped as
soon as the set torque is reached.
Gear selection, mechanical
The gear selector 5 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; for drilling with small drilling diameter.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature range is exceeded, the speed is reduced. The
power tool will not run at full speed until reaching the allow-
able battery temperature.
Activation of the temperature-controlled overload protector
is indicated by the LED 11 on the power tool lighting up red.
The LED 11 will go out once the temperature of the tool's bat-
tery is back within the permissible range.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the “Electronic Cell Protection (ECP)”. When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
The rapid shut-off feature is indicated by a flashing LED on the
power tool.
To restart the machine, release the On/Off switch and then
actuate again.
Rapid shut-off can trigger only when the power tool is
running at maximum operating speed and can rotate
freely around the drill bit axis. Choose a suitable work
position for this. Otherwise, rapid shut-off will not be en-
sured.
