Dust/Chip Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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
 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 10 RE/GSB 13 RE/GSB 16 RE)
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 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 8 through to the
right stop.
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.
To save energy, only switch the power tool on when using it.
Bosch Power Tools
Adjusting the Speed/Impact Rate
(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 Rate (GSB 16 RE)
With the thumbwheel for speed preselection 7, the required
speed/impact rate can be preselected even during operation.
The required speed/impact rate depends on the material and
the working conditions, and can be determined through prac-
tical testing.
Working Advice
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum 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 replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
