Bosch 0 603 9B0 300 Notice Originale page 17

First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
Switching on/off
To start the power tool, press and hold the on/off switch
(5).
To switch off the power tool, release the on/off switch (5).
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (5) to varying ex-
tents.
Applying light pressure to the on/off switch (5) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Emergency switch-off (KickBack Control)
The rapid shut-off function (KickBack Con-
trol) gives the user greater control over the
power tool and offers them better protec-
tion than power tools that do not have Kick-
Back Control. The power tool will switch off if it suddenly
and unforeseeably rotates around the drilling axis.
Rapid shut-off is indicated by the LED on the power tool
flashing.
To switch the tool back on, release the on/off switch and
then press it again.
It will no longer be possible to switch the power tool
u
on if the KickBack Control function is faulty. Have the
power tool serviced by a qualified repair person using
only original replacement parts.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder , are locked
when the on/off switch (5) is not pressed.
This enables screws to be screwed in even when the battery
(9) is empty and allows the power tool to be used as a
screwdriver.
Run-out brake
Upon releasing the on/off switch (5), 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 (5) once the screw has been inserted flush
into the workpiece. This way, the head of screw will not pen-
etrate the workpiece.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Bosch Power Tools
Practical advice
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
If the power tool becomes electrostatically charged, the
built-in electronics will switch the power tool off. Press the
on/off switch (5) again to restart the power tool.
Under certain conditions, strong electromagnetic fields can
negatively affect or stop the power tool. After switching the
power tool off, press the on/off switch (5) again to restart
the power tool.
Tips
The ergonomically shaped handle allows for dynamic and fa-
tigue-free handling of the power tool (see figure D).
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.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
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.
