For a spring-loaded seat as well as for a soft seat, the max-
imum tightening torque is lower than for a hard seat. Also, a
clearly longer impact duration is required.

Tips
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.
Note: Ensure that no metal particles enter the power tool.
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.
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.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Belt clip
You can use the belt clip (3) to hang the power tool on a belt,
for example. You then have both hands free and the power
tool is always at hand.
Control Via App
The power tool can be fitted with a Bluetooth®
moduleGCY42 which enables wireless data transfer to cer-
tain mobile devices with a Bluetooth® interface (e.g. smart-
phone, tablet).
In order to control the power tool via Bluetooth®, you will
need the "Bosch Toolbox" app. Download the app from the
corresponding app store (AppleApp Store, Google Play
Store).
Then select the "My Tools" sub-item in the app. The display
of your mobile terminal device will show you all subsequent
steps required to connect the power tool to the terminal
device.
The following functions will be available when a connection
has been established with the mobile device:
– Registration and personalisation
– Status check, output of warning messages
– General information and settings
– Management
– Setting the speed levels
– Setting the working modes
Maintenance and Service
Maintenance and Cleaning
u Clean the air vents on your power tool regularly. The
motor’s fan will draw the dust inside the housing and ex-
cessive accumulation of powdered metal may cause elec-
trical hazards.
u Clean the tool holder(1) and locking sleeve(2) from
time to time.
u Remove the battery from the power tool before carry-
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.
u To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
