Safety Warnings for Screwdrivers
Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may con-
tact hidden wiring. Fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against
continuous intense sunlight, fire, water, and
moisture. Danger of explosion.
In case of damage and improper use of the battery, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
The battery can be damaged by pointed objects such as
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.
Additional Safety and Working
Instructions
The battery is supplied partially charged. To ensure full
battery capacity, completely charge the battery in the
battery charger before using for the first time.
Read the operating instructions of the battery charger.
Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
When working with an application tool, pay attention
that the application tool is firmly seated on the tool
holder. When the application tool is not firmly connected
with the tool holder, it can come loose again and not be
controlled.
The torque depends on the impact duration. The maxi-
mum achieved torque results from the sum of all indi-
vidual torques achieved through impact.
Check the actually reached torque with a torque
wrench.
To save energy, only switch the power tool on when using it.
