Bosch GSR 18 VE-2 Operating Instructions Manual page 11

Changing the Tool
Open the drill chuck until the tool can be inserted.
Insert the tool.
Firmly tighten the sleeve of the keyless chuck 4
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
Directly clamp the screwdriver bit 8 into the drill
chuck or use the additional universal bit holder
when operating with hex shank bits.
Initial Operation
Inserting the Battery
Set the rotational direction switch 10 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 9.
The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 9. 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.
To switch off the machine, release the On/Off
switch 9.
Electric Brake
When releasing the On/Off switch 9 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 9. The screw head does not penetrate
into the material then.

Reversing the Rotational Direction
Operate
switch 10 only at a standstill.
a
Right Rotation (
Turn the rotational direction switch through to the
left stop (normal operation: drilling, screwdriving,
etc.).
Left Rotation (
Press the rotational direction switch through to
the right stop (for loosening and unscrewing
screws and nuts).
Gear Selection, Mechanical
Two speed ranges can be preselected with the
gear selector 1:
1st gear:
2nd gear:
The speed settings may only be changed when
the machine is motionless. If the speed setting
has not quite notched in properly, briefly press
the On/Off switch 9.
Fully Automatic Spindle Locking
(Auto-Lock)
The drill spindle is locked when the On/Off
switch 9 is not pressed.
This makes quick and easy changing of the tool
in the drill chuck possible.
The locked drill chuck enables retightening of
projecting screws by using the switched-off ma-
chine as a screwdriver.
Note: Tightening by hand with too much force
can damage the screw.
