Exchanging and removing drill bits
Fig. A + B
Before exchanging bits, first remove the
power plug from the wall socket.
Inspect bits regularly during use. Blunt
bits should be re-sharpened or replaced.
• Lightly oil the bit shaft before inserting it into
the chuck.
• Slide the locking sleeve (7) to the rear, and
insert the bit into the chuck opening. Ensure
that the keyway in the bit is seated properly in
the chuck, by carefully turning the bit until it
clicks into place. Release the locking sleeve.
• To remove the bit, slide and hold the locking
sleeve to the rear.
Setting depth gauge

user tips
Always use the machine with the auxiliary
handgrip firmly anchored in place – you will not
only work with more comfort, you will also work
with more precision.
Hammer drilling in concrete or brick
Caution: Stone drills can get very hot.
It may be necessary to drill with smaller bits and
re-drill to nominal size so that later the plug is
firmly seated.
For large bores, for instance in very hard
concrete, use a smaller bit for pilot drilling and
re-drill to nominal size.
Do not apply a lot of pressure on the machine, let
the machine do the work, guiding the machine
with light pressure is sufficient.
Hold the machine with the auxiliary handle, the bit
can jam, particularly with deep bores, and the
machine will turn.
Chipping in concrete and brick
You can also use the machine for chipping.
Prior to starting work ensure that the front selec-
tion switch and handle selection switch are fully
engaged. Do not operate the hammer drill with
selection switches in mid position. Only change
the function when the motor has come to a
standstill.
Here as well: Do not apply a lot of pressure on
the machine, let the machine do the work, guiding
