Adjusting the Drilling Depth on the Dust Extraction Attachment (see figure H)
The required drilling depth X can also be adjust- ed when the dust extraction attachment is mounted.
Insert the
Loosen the wing bolt 19 on the dust extraction attachment.
Without switching the power tool on, apply it firmly to the drilling location. The
Position the the guide pipe 20 of the dust extrac- tion attachment in its holding fixture in such a manner that the head of the dust extraction at- tachment faces against the surface to be drilled. Do not slide the guide pipe 20 further over the tel- escopic pipe 18 of the dust extraction attachment than required, so that as much as possible of the scale 18 on the telescopic pipe remains visible.
Retighten the wing bolt 19 again. Loosen the clamping screw 16 on the depth stop of the dust extraction attachment.
Move the depth stop 17 on the telescopic pipe 18 in such a manner that the clearance X shown in the figure corresponds with the required drilling depth.
Tighten the clamping screw 16 in this position.
Operation
Starting Operation
fObserve correct mains voltage! The voltage of the power 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
With the selector switch for drilling/hammer drilling 7, the operating mode of the machine is selected.
Note: Change the operating mode only when the machine is switched off! Otherwise, the machine can be damaged.
To change the operating mode, turn the selector switch for “drilling/hammer drilling” 7 to the requested position.
Position for hammer drilling in concrete or stone
Position for drilling without impact in wood, metal, ceramic and plastic as well as for screwdriving
Reversing the Rotational Direction (GBH 2-18 RE) (see figure I)
The rotational direction switch 6 is used to re- verse the rotational direction of the machine. However, this is not possible with the On/Off switch 5 actuated.
Right rotation: Push the rotational direction switch 6 rightward to the stop.
Left rotation: Push the rotational direction switch 6 leftward to the stop.
For hammer drilling and drilling, always set the direction of rotation to right rotation.
Switching On and Off
To start the machine, press the On/Off switch 5.
To lock the On/Off switch, keep it pressed and additionally push the
To switch off the machine, release the On/Off switch 5. When the On/Off switch 5 is locked, press it first and then release it.
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 5 is pressed.
Light pressure on the On/Off switch 5 results in low speed/impact rate. Further pressure on the switch increases the speed/impact rate.
