stops.
WARNING! Always disconnect the plug from the
socket before doing any work on the machine.
1. Fitting the working tools
Hammer drill (Fig.1)
Only use tools with SDS-plus shaft!
- Clean and grease the shaft of the tool.
- Before inserting the tool, move the sliding ring B back.
Now the SDS-plus chuck is open.
- Push the tool in, turn it slightly until it can be pushed in
all the way and you can feel it notch into place.
Release the sliding ring B. Now the tool is locked.
-
- Check that the tool is properly locked into place. It
must be possible to move it about 10 mm lengthways.
- Switch machine over to hammer drilling with lever E in
appropriate position.
SDS-plus adapter for geared drill chuck (Fig.2)
Fit the SDS-plus adapter P into the SDS-plus chuck as
-
described above.
- Drill chucks with 1/2" x 20 UNF mounting threads
can be screwed onto the mounting shaft. Drill bits with
cylindrical shank or screwdriver bits N can be inserted
directly into the chuck O.
2. Changing the position of the auxiliary handle
- Unscrew the auxiliary handle M in an anticlockwise
direction.
- Turn the auxiliary handle M to the required position.
- Screw the auxiliary handle M in place again.
3. Setting the depth gauge
Make sure before you start that drill-bit is inserted in
the
SDS-Plus chuck.
Slightly loosen the fixing wing nut K.
-
- 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.
- Read the value in mm off the scale on the depth gauge
L and subtract the required drill depth.
- Tighten the fixing wing nut K 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.
FUNCTIONS
1. Speed selection (Fig.1)
The speed can be controlled in infinitely variable
steps by adjusting finger pressure on the On/Off switch H.
Maximum speed is set up by handwheel C.
2. Switching over between modes (Fig.1)
For switching over between modes lever E has to be
turned. To activate this lever, first press the button D.
WARNING! Only turn the lever E when the machine
has stopped.
3. Switching between forward and reverse (Fig.1)
Select direction of rotation with reversing lever G as
shown on label F.
Only change directions when the machine has
stopped.
4. Switching the tool on and off (Fig.1)
Intermittent use
- Switching on: Press trigger switch H.
Switching off: Release trigger switch H.
-
Continuous use
Switching on: Press the On/Off switch H and then the
-
6
locking button I, after that release on-off switch.
Switching off: Press the On/Off switch H 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
1) Set the following adjustments before starting work:
Lever E in appropriate position.
-
- Clockwise rotation.
2) Fit the SDS-plus drill.
3) Place the drill against the material before switch-ing
it on, press it until the lengthways play is taken up, then
switch on and work exerting light pres-sure (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.
2. Chiselling in stone
1) Set the following adjustments before starting work:
- Lever E in suit position.
- Clockwise rotation.
2) Fit the SDS-plus chisel.
3) Apply the machine to the working material when
switched off, then switch the machine on, activate the
pneumatic hammer mechanism with high pressure at first,
then continue to work applying light pressure (e.g. 30N).
Note. Exerting greater pressure does not increase the
machine's effectiveness!

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:
Acoustic pressure = 95 dB(A)
Sound-power level = 107 dB(A)
Use ear protection!
Vibration acceleration = 14.5 m/s²
WARNING! The vibration level given in these
instructions has been measured in accordance with
a standardized measurement procedure specified in
EN60745 and can be used to compare devices. Different
uses of the device give rise to different vibration levels and
in many cases they may exceed the values given in these
instructions. It is easy to underestimate the vibration load
if the electrical power tool is used regularly in particular
circumstances.
Note. If you wish to make an accurate assessment of
the vibration loads experienced during a particular period of
working , you should also take into account the intervening
periods of time when the device is switched off or is running
