Battery Charge Indicator; Auxiliary Handle - Bosch GBH 18V-26 Professional Notice Originale

20 | English
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery
The battery (14) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release but-
ton (10) is pressed unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
– To remove the battery (14), press the release but-
ton (10) and pull the battery out of the power tool. Do
not use force to do this.

Battery charge indicator

The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.

Hammer drilling and chiselling require SDS-plus application
tools that are inserted into the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS‑plus
are used (e.g. cylindrical shank drill bits). For these tools, a
keyless chuck or a keyed chuck are required.
