uniformly on each of the three holes.
Remove the drill chuck by opening it all the way and
completely unscrewing screw A.
WARNING: Screw A has left-hand threads. Hold the shaft
at gap with a wrench and turn the drill mchuck in the
opposite direction of operation.
2. Changing the position of the auxiliary handle
1. Unscrew the auxiliary handle J in an anticlockwise
direction.
2. Turn the auxiliary handle J to the required position.
3. Screw the auxiliary handle J in place again.
3. Setting the depth gauge
Make sure before you start that drill-bit is inserted.
1. Slightly loosen the fixing wing nut J.
2. Hold the bit tip against the work surface. Push the depth
gauge L against the work surface, to the same depth as the
length of the bit.
3. Read the value in mm off the scale on the depth gauge L
and subtract the required drill depth.
4. Tighten the fixing wing nut J and adjust the resulting
value for the depth stop.
4. Mains connection
Warning! Connect only to a single-phase AC current supply
and only to the mains voltage specified on the rating plate.
Connection to sockets without earth protection is possible
as the appliance features protective class II insulation
according to European Standard EN50144. Radio
interference suppression complies with the European
Standard EN 55014.
FUNCTIONS
1. Mechanical speed shift
Low speed: Lever I should be at sign I on the head
High speed: Lever I should be at sign II on the head.
Speed may be shifted with the machine on and in either
direction.
2. Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch
J is pressed.
Light pressure on the On/Off switch J results in a low
rotational speed. Further pressure on the switch results in
an increase in speed.
3. Preselecting the Speed
With the thumbwheel for speed preselection H,
the required speed can be preselected even during

operation.

The required speed depends on the material and
the working conditions, and can be determined through
practical testing.
4. Switching over between drilling and
hammerdrilling (fig. 1)
Hammer-drilling:
Changeover switch D in position, over hammer figure.
Drilling without hammer:
Changeover switch D in position, over bit figure .
Striking mechanism may be turned on while the machine
is running.
Use hard metal drill bits to work with concrete, stone and
rubblework.
Only ever switch over when the machine is stationary or
slowing down. Only ever operate the machine rotating
clockwise when drilling.
5. Switching between forward and reverse.
These models are provided with a reversing lever in the
6
switch which allows the drill to be used as an screwdriver.
Select direction of rotation with turn direction lever E as
shown on label O, i.e., R=right sense, K=left sense. Due to
a lockout mechanism, the turn direction lever EI can only
be switched when the On-/off switch F is not depressed.
Only enable the turn direction lever E when the machine
has stopped.
Only ever operate the machine rotating to the right when
hammer-drilling or when chiselling!
6. Switching the tool on and off Intermittent use
Switching on: Press trigger switch F.
Switching off: Release trigger switch F.
Continuous use
Switching on: Press the On-/off switch F and then the
locking button G, after that release on-off switch F.
Switching off: Press the On-/off switch F and then release.
The speed can be controlled continuously during the
operation by adjusting finger pressure on the On-/off
switch.
OPERATION
1. Hammer-drilling
Set the following adjustments before starting work:
- Lever D over hammer figure for Hammerdrilling operation.
- Clockwise rotation.
2. Fit the drill.
3. Place the drill against the material before
switching it on, press it until the lengthways play is
taken up,
then switch on and work exerting light pressure (e.g. 30N).
Note Exerting greater pressure does not increase the
machine's effectiveness!
Tips on drilling in masonry:
• Take the drill out of the hole from time to time to remove
dust.
• Switch to percussion-drilling for concrete, hard bricks
and tiles, stone and hard cement (but not when drilling the
surface of marble).
• For tiles, paving-stones, soft bricks and tiles, soft cement,
breeze-block and plaster, switch to normal drilling.
• Use percussion carbide-tipped masonry drill-bits.
• When drilling a hard, smooth surface (e.g. tiles), cover the
point to be drilled with adhesive tape in order to prevent the
drill tip from skidding.

NOISE AND VIBRATION

This tool has been designed and made to reduce
noise to a minimum. However, in spite of this, in certain
circumstances the maximum noise level in the place of
work could exceed 85 dBA. In this case, the operator
should wear ear protection.
The machine's noise and vibration levels, measured in
compliance with EN60745, usually reach:
Noise values
Sound pressure level LpA
Sound power level LWA
Uncertainty K
Vibration values
