Changing the Tool
Before any work on the machine itself, re-
move the battery.
With the SDS-plus tool holder, simpler and easier
tool changing is possible without additional aids.
Grease the shank end of the tool regu-
larly.
The dust protection cap 1 largely prevents the
entry of drilling dust during operation. When in-
serting the tool, take care that the dust protection
cap 1 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
As a requirement of the system, the
SDS-plus tool must rotate freely. At no-load
speed, this leads to a certain amount of ra-
dial run-out.
This does not affect the accuracy of the drill
hole, as the bit is automatically centred dur-
ing drilling.
Inserting (see figure
Clean and grease the shank end of the tool.
Insert the tool in a twisting manner into the tool
holder until it locks. Check if it has locked by pull-
ing the tool.
Removing (see figure
Push back the locking sleeve 2 of the tool holder
and remove the tool.

Initial Operation
Inserting the Battery
Set the rotational direction switch 7 to the centre
position (lock-off). Insert the charged battery 8
into the handle until it can be felt to engage and
is seated flush on the machine.
Switching On and Off
To start the machine, push the On/Off switch 6
and keep it pushed.
The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 6. Light pres-
sure on the On/Off switch 6 results
in low rotational speed, thus allow-
ing drilling to begin in a smooth,
controlled manner. Further pres-
sure on the switch results in an in-
crease in speed.
To switch off the machine, release the On/Off
switch 6.
Do not strain the machine so heavily that it comes
to a standstill.
Overload Clutch
If the drill bit jams or edges, the drive to the
drill spindle is interrupted.
Due to the arising forces always hold the
machine firmly with both hands and
provide for a secure stance.
Before pulling out a stuck tool insert, first remove
the machine from it.
Reversing the Rotational Directions
Operate
the
switch 7 only at a standstill.
The rotational direction switch 7 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On /Off
switch 6 actuated.
rotational
direction
Right Rotation
Turn the rotational direc-
tion switch through to
the left stop (normal op-
eration: drilling, screw-
driving, etc.).
Left Rotation
Press the rotational di-
rection switch through to
the right stop (for loos-
ening and unscrewing
screws and nuts).
