Adjusting the Drilling Depth on the Dust Extraction At-

tachment (see figure G)

The required drilling depth X can also be adjusted when the

dust extraction attachment is mounted.

– Insert the SDS-plus drilling tool to the stop into the SDS-

plus tool holder 1. Otherwise, the movability of the SDS-

plus drilling tool can lead to incorrect adjustment of the

drilling depth.

– Loosen the wing bolt 20 on the dust extraction attach-

ment.

– Without switching the power tool on, apply it firmly to the

drilling location. The SDS-plus drilling tool must face

against the surface.

– Position the the guide pipe 21 of the dust extraction at-

tachment in its holding fixture in such a manner that the

head of the dust extraction attachment faces against the

surface to be drilled. Do not slide the guide pipe 21 further

over the telescopic pipe 19 of the dust extraction attach-

ment than required, so that as much as possible of the

scale 19 on the telescopic pipe remains visible.

– Retighten the wing bolt 20 again. Loosen the clamping

screw 17 on the depth stop of the dust extraction attach-

ment.

– Move the depth stop 18 on the telescopic pipe 19 in such

a manner that the clearance X shown in the figure corre-

sponds with the required drilling depth.

– Tighten the clamping screw 17 in this position.

Operation

Starting Operation

f Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

Setting the Operating Mode

The operating mode of the power tool is selected with the

mode selector switch 5.

Note: Change the operating mode only when the machine is

switched off! Otherwise, the machine can be damaged.

– Turn the mode selector switch 5 to the requested position.

Reversing the Rotational Direction

f Actuate the rotational direction switch 8 only when the

machine is at a standstill.

The rotational direction switch 8 is used to reverse the rota-

tional direction of the machine.

Right rotation: Turn the rotational direction switch 8 to the

stop in the position .

Left rotation: Turn the rotational direction switch 8 to the

stop in the position .

Set the direction of rotation for hammer drilling, drilling and

chiselling always to right rotation.

Switching On and Off

–To start the machine, press the On/Off switch 7 and keep

it pressed.

– To switch off the machine, release the On/Off switch 7.

For low temperatures, the power tool reaches the full ham-

mer/impact capacity only after a certain time.

Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be

variably adjusted, depending on how far the On/Off switch 7

is pressed.

Light pressure on the On/Off switch 7 results in low speed/im-

pact rate. Further pressure on the switch increases the

speed/impact rate.

Safety Clutch

f 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.

f If the power tool jams, switch the machine off and loos-

en the tool insert. When switching the machine on with

the drilling tool jammed, high reaction torques can oc-

cur.

Changing the Chiselling Position (Vario-Lock)

The chisel can be locked in 13 positions. In this manner, the

optimum working position can be set for each application.

– Insert the chisel into the tool holder.

– Turn the mode selector switch 5 to the “Vario-Lock” posi-

tion (see “Setting the Operating Mode”, page 16).

– Turn the tool holder to the desired chiselling position.

– Turn the mode selector switch 5 to the “chiselling” posi-

tion. The tool holder is now locked.

– For chiselling, set the rotation direction to right rotation.

Position for drilling without im-

pact in wood, metal, ceramic and

plastic as well as for screwdriving

Position for hammer drilling in

concrete or stone

When the drilling tool does not

immediately rotate upon switch-

ing on, allow the machine to run

slowly until the drilling tool ro-

tates.
