 Before switching on the power tool, make sure that the
application tool moves freely. When switching on with a
blocked drilling tool, high torque reaction can occur.
 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.
 Avoid unintentional switching on. Ensure the On/Off
switch is in the off position before inserting battery
pack. Carrying the power tool with your finger on the
On/Off switch or inserting the battery pack into power
tools that have the switch on invites accidents.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against con-
tinuous 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.
 Use only original Bosch batteries with the voltage list-
ed on the nameplate of your power tool. When using oth-
er batteries, e.g. imitations, reconditioned batteries or
other brands, there is danger of injury as well as property
damage through exploding batteries.
 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.
 Check the tight seating of the battery. Two locking lev-
els are possible.
 The battery pack can be damaged by pointed objects
such as nails or screwdrivers or by force applied exter-
nally. An internal short circuit can occur and the battery
pack can burn, smoke, explode or overheat.
