not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
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 their hands warm,
and organising workflows correctly.
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.
Using the GCY 42 Bluetooth® Low Energy
Module
Read the corresponding operating instructions for informa-
tion about the Bluetooth® Low Energy Module GCY 42.
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: 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 (11) is equipped with two locking levels to pre-
vent the battery from falling out when pushing the battery re-
lease button (12) 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 (11), press the release button (12)
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 (14) (see "Status Indications", page 22).

Auxiliary handle
Do not operate your power tool without the auxiliary
u
handle (4).
This power tool must only be used with the auxiliary
handle with the order number 1 602 025 07Y.
Before carrying out any work, make sure that the aux-
u
iliary handle is tightened. Loss of control can cause per-
sonal injury. Ensure that the auxiliary handle is tightened
with a torque suited to the fastening method; fasten this
to the power tool so that any movement of the auxiliary
handle around or along the drilling axis is avoided.
Fitting the auxiliary handle
To open the auxiliary handle, turn the lower gripping end of
the auxiliary handle (4) in an anticlockwise direction.
Pull back the intermediate piece of the auxiliary handle and
hold it in this position.
Slide the auxiliary handle over the drill chuck to mount the
auxiliary handle on the power tool.
Then let go of the intermediate piece .
Afterwards, turn the lower gripping end of the auxiliary
handle (4) clockwise to retighten it.
