drill chuck

you can use the tool. The spindle

lock releases automatically when the motor starts.

QFirst use

The mains voltage at the mains socket must match that shown on the rating plate on the device. Devic- es marked with 230 V can also be operated at 220 V.

jThe most suitable speed depends on the mate- rial involved. We recommend that you carry out a few practical tests beforehand.

Tip: You will always find these two basic guide- lines helpful:

1.Large drill diameter = lower speed whilst smaller drill diameter = higher speed

2.Hard material = lower speed

QSwitching on and off

When operating the hammer-action drill you can select between intermittent or continuous operation mode. Use intermittent operation mode for shorter drilling jobs and continuous operation mode for longer drilling jobs. In either mode the device func- tions as follows:

To switch on intermittent operation mode:

jPress the ON / OFF switch 2 .

To switch off intermittent operation mode:

jRelease the ON / OFF switch 2 .

To switch on continuous operation mode:

jPress the ON / OFF switch 2 , keep it pressed and press the lock switch 3 .

To switch off continuous operation mode: j Press and then release the ON / OFF switch 2 .

QSelecting the direction of rotation

CAUTION! Only change the position of the rota- tion direction switch 5 after the device has come to a standstill.

jSet the direction in which you wish the drill to rotate by using the rotation direction switch 5 .

QSelecting the gear

CAUTION! The gear selector switch 6 must only be moved after the device has come to a standstill.

jSelect the speed range using the gear selector switch 6 :

1 = low speed range

2 = high speed range

QInfinitely adjustable speed setting

The ON / OFF switch 2 has a variable speed control.

jPressing the ON / OFF switch 2 increases the speed.

QPreselecting the rotation speed

You can pre-select the required speed in ratchet steps (A-F) using the speed preselector wheel 4 .

QSwitching between drilling / hammer-action

Note: The drill / hammer-action switch 1 must only be moved after the device has come to a standstill.
