Rechargeable Battery; Inserting The Battery; Battery Charge Indicator; Auxiliary Handle - Bosch GBH 18V-21 Professional Notice Originale

Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.

Rechargeable battery

Charging the battery
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: Lithium-ion rechargeable batteries are supplied par-
tially charged according to international transport regula-
tions. To ensure full rechargeable battery capacity, fully
charge the rechargeable battery before using your tool for
the first time.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.

Inserting the Battery

Push the charged battery into the battery holder until it
clicks into place.
Removing the Battery
To remove the rechargeable battery, press the battery re-
lease button and pull the battery out. Do not use force to do
this.
The rechargeable battery has two locking levels to prevent
the battery from falling out if the battery release button is
pressed unintentionally. The rechargeable battery is held in
place by a spring when fitted in the power tool.

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.

Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Auxiliary handle

Do not operate your power tool without the auxiliary
u
handle (14).
Make sure that the auxiliary handle is always
u
tightened. Otherwise you could lose control of the power
to
tool when working.
Swivelling the auxiliary handle (see figure A)
You can swivel the auxiliary handle (14) to any angle for a
safe work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (14)
anticlockwise and swivel the auxiliary handle (14) into
the required position. Then turn the lower gripping end of
the auxiliary handle (14) clockwise to retighten it.
Make sure that the retaining strap of the auxiliary handle
slots into the corresponding groove of the housing.
