Battery Charging
u
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 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.
u
Do not continue to press the On/Off switch after the
power tool has automatically switched off.
The battery
can be damaged.
Follow the instructions on correct disposal.
Battery Charge Indicator
The battery charge indicator (6) indicates the state of
charge for a few seconds when the on/off switch (9) is half
or fully pressed.
LED Capacity
Green continuous light ≥ 66%
Orange continuous light > 33%−66%
Red continuous light > 11%−33%
Flashing light, red ≤ 11%
If no LED lights up after switching the power tool on, then
the battery is defective and must be replaced.
Inserting and removing the battery (see figures
A1–A2)
u
Do not use force to insert the battery. The battery is de-
signed in such a way that it can only be inserted into the
power tool when it is in the right position.
– Slide the battery (10) all the way into the battery bay.
– To remove the battery (10) , press the release but-
ton (19) on the battery and pull it out of the battery bay.
Selecting drill chucks and tools
An SDS quick application tool is required for hammer
drilling.
To drill without impact in wood, metal, ceramic and plastic
you can use a suitable SDS quick application tool, a
hexagonal shank application tool or the keyless chuck with
application tools that do not have SDS quick.
For screwdriving, only use screwdriver bits which have a ball
catch
(14) (DIN 3126-E6.3). Other screwdriver bits (13)
can be inserted using a universal bit holder with ball catch
(12) .
You will find a selection of suitable application tools in the
accessories overview at the end of these operating instruc-
tions.
Changing the Keyless Chuck
You must use the keyless chuck (20) to work with applica-
tion tools that do not have SDS-Quick (e.g. cylindrical shank
drill bits).
Inserting the keyless chuck (see figure B)
– Clean and lightly grease the insertion end of the shank.
– Insert the keyless chuck
(20) with the shank into the tool
holder while turning it until it locks automatically.
– Check that it is locked by pulling the keyless chuck.
Removing the Keyless Chuck
– Push the locking sleeve (3) back and remove the keyless
chuck (20) .
Changing the Tool
The tool holder can also accommodate dif-
ferent application tools with a hexagonal
shank with groove and SDS quick shank.
The tool holder allows for simple and con-
venient tool-free changing of the application
tool.
As a requirement of the system, the application tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
The dust protection cap
(2) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap
(2)
does not become damaged.
u
Replace a damaged dust protection cap immediately.
It is recommended that you have use an after-sales
service for this.
Inserting SDS-Quick application tools (see figure C)
– Clean and lightly grease the insertion end of the applica-
tion tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
Removing SDS-Quick application tools (see figure D)
– Push the locking sleeve (3) back and remove the applica-
tion tool.
Inserting application tools that do not have SDS quick
(see figure E)
Note:
Application tools that do not have SDS-Quick must not
be used for hammer drilling. Hammer drilling will damage
tools without SDS-Quick along with their chucks.
– Insert the keyless chuck
(20) .
– Hold the rear sleeve (22) of the keyless chuck (20) firmly
and turn the front sleeve (21) anti-clockwise until the tool
can be inserted. Insert the tool.
