Reversing the Rotational Direction

The rotational direction switch 7 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On /Off switch 8
pressed.
Right Rotation
Press the rotational direction
switch through to the right stop
(normal operation).
Left Rotation

tion:

Safety Clutch
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always hold the
power tool firmly with both hands and provide for
a secure stance.
If the drilling tool jams, switch the machine off and
loosen the drilling tool. When switching the machine
on with the drilling tool jammed, high reaction tor-
ques can occur!
Changing the Chiselling
Position
The chisel can be locked in 36 positions. In this man-
ner, the optimum working position can be set for
each application.
Insert the chisel in the tool holder.
Turn the mode selector switch 6 to "Changing the
chiselling position".
Turn the tool holder to the desired chiselling position.
Allow the mode selector switch 6 to latch in the
"Chiselling" position. The tool holder is locked in this
position.

Maintenance and Cleaning

Before any work on the machine itself, remove
the battery.
For safe and proper working, always keep the
machine and the ventilation slots clean.
Keep the tool holder clean at all times.
Changing the Dust Protection Cap
A damaged dust protection cap should be changed
immediately. We recommend having this carried
out by an after-sales service.
If the machine should fail despite the care taken in
manufacturing and testing, repair should be carried
out by a Würth Master-Service agent.
For all correspondence and spare parts orders,
always include the article number on the type plate
of the machine.
