Bosch Professional GBH 18V-34 CF Original Instructions Manual page 9

The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
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
button (18) is pressed unintentionally. As long as the bat-
Bosch Power Tools
tery is inserted in the power tool, it is held in position by
means of a spring.
– To remove the battery (12), press the release
button (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.
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.
