Slide the centralizing disc into position.
Ø 68 mm / Ø 82 mm

To dismantle, use the open-ended spanner to unscrew the drill bits.
4.2 Power Puls changeover (B)
For hard rock, changeover to soft hammer action.
Do not use the hammer action at the start of drilling and for brittle stone (e.g. tiles).
4.3 Overload protection (C)
The green warning lamp is on during normal operation.
If too much pressure is exerted on the drill bit the red warning lamp will come on. Reduce the
pressure and the green lamp will come on again.
In the event of continuous overloading, the electronic system of the machine will switch the ma-
chine off. To continue working, switch the machine off and then on again.
In the case of jerking overload (e.g. drill bit catches) the electronically controlled slipping clutch
will interrupt the power supply.
4.4 Switching On / Off (D)
Switch the machine on or off at the switch button.
The speed can be altered at the switch button.
4.5 Handle attachment (E)
The handle attachment can be fitted on the left or right side.
Extensive torque is created when drilling with core drills; never work without the handle
attachement!
4.6 Dust extraction (F)
Always work with dust extraction switched on. The machine is fitted with an efficient dust
extraction system. We recommend the ROTHENBERGER RODIA DRY CLEANER 1600
extractor.
