Tip: Start drilling holes at low speed. Then increase
the speed in stages.
Benefits:
n The drill bit is easier to control when starting the
hole and will not slide away.
n You avoid drilling messy holes (for example in
tiles).
6.3 Preselecting the speed (Fig. 11/Item 6)
n The speed setting ring (6) enables you to define
the maximum speed. The ON/OFF switch (5) can
only be pressed to the defined maximum speed
setting.
n Set the speed using the setting ring (6) on the
ON/OFF switch (5).
n Do not attempt to make this setting whilst the drill
is in use.
6.4 Clockwise/Counter-clockwise switch
(Fig. 11/Item 7)
n Change switch position only when the drill is
at a standstill!
n Switch the direction of the hammer drill using the
clockwise/counter-clockwise switch (7):
Direction Switch position
Clockwise (forwards and drill) Pushed in to the right
Counter-clockwise (reverse) Pushed in to the left
6.5 Drill / hammer drill selector switch
(Fig. 12/Item 3)
Change switch position only when the drill is at a
standstill!

6.6 Drilling with the dust extraction system (9)
Use the dust extraction system only for drilling into
concrete, bricks and masonry since wood or plastic
chips may block the extraction system. Do not drill
into metallic materials since hot metal chips can
damage the dust extraction system.
n Fit the dust extraction system (9); see point 5.3.
n Connect the dust extractor adapter (10) to the
suction hose of a suitable vacuum cleaner. The
vacuum cleaner must be suitable for handling the
substance that will be extracted. Harmful dust
must not be extracted using the dust extraction
system (9). Use on materials containing
asbestos is prohibited!
n Set the required drilling depth (see point 5.2).
n Mark the drilling position.
n Tip: To prevent the wall being soiled, you can
mask the area around the transparent extraction
opening with masking tape. Before you use the
masking tape, test whether the tape can be
removed easily from the wall again in a place
that it not easily visible.
n Switch on the vacuum cleaner and place the
transparent cover on the front of the dust
extraction system (9) over the drilling point so
that the drill bit is in front of the mark. Ensure that
the transparent cover is in contact with the
workpiece or wall.
n Press the drill bit and machine gently against the
mark whilst the ON/OFF switch (5) is still set to
off.
n Then drill the hole. See the instructions in point
6.7 for more details.
n The dust extraction system (9) must be cleaned
after at least every 15 holes. For this purpose
remove the dust extraction system (9) and the
additional handle (8) as described in points 5.3
and 5.1. Clean the dust extraction system (9)
and the interior of the additional handle (8) by
carefully tapping them or blowing them through
with low pressure compressed air.
n If the extraction performance is poor, check the
dust extraction system (9) for possible blockages
or dirt.
n The transparent cover is enclosed in a protective
ring to prevent it from suffering damage. This
protective ring should be replaced as soon as it
is damaged or worn.
6.7 Tips for working with your hammer drill
6.7.1 Drilling concrete and masonry
n Switch the Drill/Hammer drill selector switch (3)
to position B (Hammer drill).
n Always use carbide drill bits and a high speed
setting for drilling into masonry and concrete.
6.7.2 Drilling steel
n Switch the drill / hammer drill selector switch (3)
to position A (drill).
n Always use HSS drill bits (HSS = high speed
steel) and a low speed setting for drilling steel.
n We recommend that you lubricate the hole with a
suitable cutting fluid to prevent unnecessary drill
bit wear.
