Bosch GSR 12V-30 Professional Notice Originale page 11

A light pressure on the on/off switch (10) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Setting the speed/impact rate (GSB 12V-30)
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (10) to varying ex-
tents.
Applying light pressure to the on/off switch (10) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder (1), are
locked when the on/off switch (10) is not pressed.
This enables screws to be screwed in even when the battery
(8) is empty and allows the power tool to be used as a
screwdriver.
Run-out brake
Upon releasing the on/off switch (10), the drill chuck is
slowed down, which prevents the application tool from con-
tinuing to rotate.
When driving in screws, you should therefore only release
the on/off switch (10) once the screw has been inserted
flush into the workpiece. This way, the head of screw will not
penetrate the workpiece.
Practical advice
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills
(HSS = high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
Before screwing larger, longer screws into hard materials, it
is advisable to pre-drill a pilot hole with the core diameter of
the thread to approx. 2/3 of the screw length.
Maintenance and Service
Maintenance and Cleaning
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
