Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Reversing the rotational direction (see figures G–H)
(GSB 13 RE/GSB 16 RE)
Actuate the rotational direction switch 8 only when the
machine is at a standstill.
The rotational direction switch 8 is used to reverse the rota-
tional 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 upward on the left side and at the
same time downward on the right side.
Left Rotation: For loosening and unscrewing screws and
nuts, push the rotational direction switch 8 downward on the
left side and at the same time upward on the right side.
Setting the operating mode
Drilling and Screwdriving
Set the selector switch 4 to the "Drilling" symbol.
Impact Drilling
Set the selector switch 4 to the "Impact drilling"
symbol.
The selector switch 4 engages noticeably and can also be ac-
tuated with the machine running.
Switching On and Off
To start the machine, 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 machine, release the On/Off switch 6 or
when it is locked with the lock-on button 5, briefly press the
On/Off switch 6 and then release it.
Adjusting the Speed/Impact Frequency
(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/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Preselecting the Speed/Impact Frequency (GSB 16 RE)
With the thumbwheel for speed preselection 7, the required
speed/impact frequency can be preselected even during op-
eration.
The required speed/impact frequency depends on the mate-
rial and the working conditions, and can be determined
through practical testing.
Bosch Power Tools
Working Advice
Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow 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 until after drilling through the tile.
Use carbide tipped drill bits when working in concrete, ma-
sonry and brick wall.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Twist drills from 2.5–10 mm can easily be sharpened with
the drill bit sharpener (see accessories).
GSB 16 RE
We recommend the use of a drill stand (see accessories) for
work where greater precision is particularly required.
The machine vice, which is available as an accessory, enables
secure clamping of workpieces. This prevents the workpiece
from turning and any accidents this would cause.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull the mains
plug.
For safe and proper working, always keep the machine
and ventilation slots clean.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
