Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the type plate of the
power tool.
Reversing the Rotational Direction
(see figures G–H)
(GSB 10 RE/GSB 13 RE/GSB 16 RE)
The rotational direction switch 8 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 6 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 8 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Switching On and Off
To start the power tool, press the On/Off switch
6 and keep it pressed.
To lock the pressed On/Off switch 6, press the
lock-on button 5.
To switch off the power tool, release the On/Off
switch 6 or when it is locked with the lock-on but-
ton 5, briefly press the On/Off switch 6 and then
release it.
Adjusting the Speed/Impact Frequency
(GSB 10 RE/GSB 13 RE/GSB 16 RE)
The speed/impact rate of the switched on power
tool can be variably adjusted, depending on how
far the On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Preselecting the Speed/Impact Frequency
(GSB 16 RE)
With the dial control for speed preselection 7,
the required speed/impact frequency can be pre-
selected even during operation.
Bosch Power Tools
The required speed/impact frequency depends
on the material and the working conditions, and
can be determined through practical testing.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 4 to the "Drill-
ing" symbol.
Hammer Drilling
Set the selector switch 4 to the "Ham-
mer drilling" symbol.
The selector switch 4 engages noticeably and can
also be actuated with the machine running.
Working Instructions
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
Tips
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
For drilling in tiles, set the selector switch 4 to
the "Drilling" symbol. Do not switch over to the
symbol "Impact Drilling" or work with impact un-
til after drilling through the tile.
Use carbide tipped drill bits when working in
concrete, masonry and brick wall.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS = High Speed Steel).
The appropriate quality is guaranteed by the
Bosch accessories program.
Twist drills from 2.5–10 mm can easily be sharp-
ened with the drill bit sharpener (see accesso-
ries).
GSB 16 RE
We recommend the use of a drill stand (see ac-
cessories) for work where greater precision is
particularly required.
The machine vice, which is available as an acces-
sory, enables secure clamping of workpieces.
This prevents the workpiece from turning and
any accidents this would cause.
