Battery Charging; Battery Charge Indicator; Auxiliary Handle - Bosch GBH 18V-34 CF Professional Originalbetriebsanleitung

Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Assembly
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change, etc.) as well as during
transport and storage, press the lock-on button to
lock the on/off switch. There is risk of injury from unin-
tentionally pressing the on/off switch.
Using the GCY 42 Bluetooth ® Low Energy
Module
Read the corresponding operating instructions for informa-
tion about the Bluetooth® Low Energy Module GCY 42.

Battery Charging

Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
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 (12) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release but-
ton (18) 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 (12), press the release but-
ton (18) 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.
Bosch Power Tools
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.
Note: The state of charge of the battery is also displayed on
the user interface (19) Status indications.

Auxiliary handle

Do not operate your power tool without the auxiliary
u
handle (16).
Swivelling the auxiliary handle (see figure A)
You can swivel the auxiliary handle (16) to any angle for a
safe work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (16)
anticlockwise and swivel the auxiliary handle (16) into
the required position. Then turn the lower gripping end of
the auxiliary handle (16) clockwise to retighten it.
Make sure that the retaining strap of the auxiliary handle
slots into the corresponding groove of the housing.
Setting the drilling depth (see figure B)
You can use the depth stop (17) to set the required drilling
depth X.
– Press the button for depth stop adjustment (15) and in-
sert the depth stop into the auxiliary handle (16).
The fluting on the depth stop (17) must face downwards.
– Push the SDS plus application tool into the SDS plus tool
to
holder (3) as far as it will go. Otherwise, the movability of
the SDS-plus drilling tool can lead to incorrect adjustment
of the drilling depth.
