Typically the A-weighted noise levels of the product are:
Sound pressure level 87 dB(A); Sound power level 98 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
Inserting the Bluetooth® Low Energy Module
GCY 30-4 (accessory)
Read the corresponding operating instructions for informa-
tion about the Bluetooth® Low Energy Module GCY 30-4.
Battery Charging
Use only the chargers listed in the technical data. Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery supplied is partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is

empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Removing the battery (see figure A)
The battery 5 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 6 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 5, press the unlocking button 6 and
pull out the battery toward the front. Do not exert any force.
Observe the notes for disposal.
Changing the Tool
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Inserting (see figure B)
Insert the application tool all the way into the mounting 1.
Mounting the Adapter (see figure C)
Remove the application tool.
Insert the adapter into the mounting 1. Turn the locking ring
15 until it audibly engages.
Inserting the Application Tool into the Adapter
GFA 18-E (see figure D):
Push back the locking sleeve and insert the tool in a twisting
manner into the tool holder. Release the locking sleeve again
in order to lock the tool.
GFA 18-M/GFA 18-B (see figure E):
Open the drill chuck adapter 11 by turning it in direction of ro-
tation until the application tool can be inserted. Insert the
application tool.
Firmly tighten the sleeve of the drill chuck adapter 11 by turn-
ing it by hand in direction of rotation . This will automatical-
ly lock the drill chuck.
Turning the Adapter (see figure F)
Pull the locked adapter approx. 5 mm away from the power
tool. Turn the adapter to the required position and then let it
go.
