Position for chiselling
Switching On and Off
– If necessary, release the lock-on button (7) for the on/off
switch.
– To switch on the power tool, press the on/off switch (9).
The worklight (10) lights up when the on/off switch (9) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
– To switch off the power tool, release the on/off switch
(9).
For low temperatures, the power tool reaches the full ham-
mer/impact capacity only after a certain time.
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 (9) to varying ex-
tents.
Applying light pressure to the on/off switch (9) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
You can also control the speed on the user interface and/or
via a smartphone app (see "Selecting the working mode",
page 20).
Overload clutch
If the application tool jams or snags, the power trans-
u
mission to the drill spindle will be interrupted. Always
Status indications
Battery charge indicator Meaning/cause
(user interface) (16)
Green (2 to 5 bars) Battery charged
Yellow (1 bar) Battery almost empty
Red (1 bar) Battery empty
Temperature indicator (22) Meaning/cause
Yellow Operating temperature of the battery or the
power tool has significantly increased, per-
formance is reduced
Red Operating temperature of the battery or the
power tool has been exceeded, power tool
switches itself off as a precautionary measure
Bosch Power Tools
hold the power tool firmly with both hands to with-
stand the forces this may create and adopt a position
with stable footing.
Switch the power tool off immediately and remove the
u
application tool if the power tool becomes blocked.
Switching on when the drilling tool is blocked may
cause high torque reactions.
Rapid shut-off (KickBack Control)
The rapid shut-off function (KickBack
Control) gives the user greater control
over the power tool and offers them bet-
ter protection than power tools that do
not have KickBack Control. If the power
tool suddenly and unforeseeably rotates
around the drilling axis, it will switch off
and the rapid shut-off indicator (17) will
light up and the worklight (10) will flash.
When rapid shut-off is activated, the
status indicator (20) flashes red.
– To switch the tool back on, release the on/off switch (9)
and then press it again.
Electronic Precision Control (EPC)
EPC assists you when working with impact by ensuring slow
start-up of the operating speed for precise working.
Adaptive Speed Control in "Chiselling" Operating Mode
For better control and precise position-
ing, the power tool starts at a low speed
and then quickly increases to the max-
imum speed.
Adapted Speed Control is started up
automatically when the power tool is
switched on.
User Interface (see figure F)
The user interface (14) is used to select the working mode
and to indicate the status of the power tool.
Solution
–
Replace or charge battery soon
Replace or charge battery
Solution
Run the power tool at no load and allow it to
cool down or replace the overheated battery
Leave the power tool to cool down or replace
overheated batteries
