Flashing red light indicates that:
a. Kickback Control is triggered (the
Kickback Control indicator 9e is also
flashing) or
Flashing blue light indicates that the
power tool is connected to a mobile
device or settings are being transferred.
To accept the change of settings from
the mobile device press work preset

WORK PRESETS
The work preset button 9g allows you
switch between work presets:
In Auto work preset, the power tool
reaches maximum performance.
- For "Drilling" operating mode: Rapid
increase in speed for controlled
drilling up to maximum RPM.
Kickback control is enabled.
- For "Hammering" operating mode:
Rapid increase in speed up to
maximum BPM when chiseling is
started.
Soft work preset is used to work with
delicate materials.
- For "Drilling" operating mode: Slow
increase in speed for controlled
drilling. Kickback control is enabled.
- For "Hammering" operating mode:
Soft start is enabled for precise
control and positioning with a
variable speed control in the trigger.
In Favorite work preset, the power tool
can be customized via 'Bosch Toolbox'
app.
- For "Drilling" operating mode: Ramp-
up speed and maximum RPM can be
customized. The sensitivity of
Kickback Control can be configured.
- For "Hammering" mode: Soft start
can be enabled/disabled.
Refer to "Using 'Bosch Toolbox' app"
chapter for more information.
Adaptive Speed Control
In "Hammering" operating
mode, the power tool starts
at a low idle speed for better
control
positioning. When force is
applied to the workpiece, the speed
quickly increases.
Operating Instructions
and precise
-16-
Slip Clutch
The tool has a internal pre-set slip
clutch. The output spindle will stop
rotating if the accessory binds and
overloads the tool.
Vibration damping
the generated vibration.
Do not use the power tool if the
vibration damper 5 is damaged (Fig. 1).
Kickback Control
The rapid shut-off feature
enables better control and
improves user's comfort. The
power tool automatically shuts
off in case of sudden and
unexpected rotation of the power tool
around the drilling axis (for example
jamming of the drill bit in reinforcing steel
or wedging application tool). To restart
the power tool, release the trigger switch
and then actuate again.
Kickack Control can activate only when
the power tool is running at maximum
operating speed and can rotate freely
around the drill bit axis.
Tool Tips
For the best penetration rates in
concrete, run the tool with a steady
pressure, but do not use excessive force
as this will decrease the efficiency of
the tool.
All hammers require a short period of
time to warm up. Depending on the
room temperature, this time may vary
from approximately 15 seconds (90°F /
32°C) to 2 minutes (32°F / 0°C). A new
hammer requires a break-in period
before full performance is realized. This
period may require up to 5 hours of
operation.
A combination hammer is likely to be
the most expensive portable tool at the
construction job. The long wear and
efficient operation of the BOSCH
hammers will more than justify the cost
for tools of this type. As earlier pointed
out, sharp accessories as well as clean
