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.

Using the GCY 42 Bluetooth® Low Energy
Module
Note: The GCY 42 Bluetooth ® Low Energy Module is avail-
able as an accessory with GWS 18V-15 C power tools; it is
included in the scope of delivery for GWS 18V-15 SC power
tools.
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 (7) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release button
(8) is pressed unintentionally. As long as the battery is inser-
ted in the power tool, it is held in position by means of a
spring.
To remove the battery (7), press the release button (8) 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 (4) (see "Status indications", page 30).
