Bosch Professional GSR 12V-15 FC Original Instructions Manual page 11

Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (7) to varying extents.
A light pressure on the on/off switch (7) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the holder (1), are locked
when the on/off switch (7) is not pressed.
This enables screws to be screwed in even when the battery
is empty and allows the power tool to be used as a screw-
driver.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted operating temperature range, the power output is
reduced or the power tool is switched off. The power tool
will not run at full power output again until the permitted op-
erating temperature has been reached.
Battery charge indicator
When the on/off switch (7) is pressed in halfway or com-
pletely, the battery charge-control indicator (8) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
LEDs
3× continuous green light
2× continuous green light
1× continuous green light
1× flashing green light
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
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
