Handling
Please read and be sure to understand the drill rig instruction manual for opera-
tion in the drill rig.
Overload protection
The green control lamp illuminates during normal operation. The red control lamp illuminates if
excessive pressure is applied to the drill bit. Reduce the contact pressure; the green control
lamp illuminates again.
The electronic system shuts the equipment down in the case of overloading for a longer period
of time. Switch the equipment off and then on again in order to continue working. In the event of
jerky overloading (e.g. jamming of the drill bit) the friction coupling interrupts the force flow.
Setting the speed
Set the speed according to the diameter and the type of the material, according to the label.
Only change gears when the equipment is at a standstill.
Wet drilling
Danger due to electric shock! Always carry out work using a water extraction
device when wet drilling overhead. The water extraction device must be in a
flawless condition.
Turn on the water connection and switch on the water extractor.
(There must at least be sufficient water pressure (
max. 4 bar!
) to move the arising drilling
mud from the borehole)
Freehand operation wet suction: Insert the drill bit into the water suction ring while it is sta-
tionary and check before whether the water suction device has been firmly stuck by suckers
to the wall or the floor and is being held firmly.
Please note:
Never drill from the bottom up when using the centering aid in order to avoid
the danger of an accident in the event of unintentional release of the centering aid. The
water suction ring can come loose during drilling!
Switch on the motor.
Apply the diamond drill bit and continue to drill using light, consistent follow-up pressure.
Occasionally with draw the drill bit slightly from the bore so that the drilling mud or dust is
removed.
Shut down the motor once the desired drilling depth has been achieved and pull the drilling
bit out of the borehole slowly.
Stop the supply of water and shut down the water extractor.
If no more boreholes are required, allow the motor to run again for a few seconds without
water supply in order to press the remaining water out of the rinsing bush of the motor.
In case of seizure, start up the drill motor again at low speed using cooling water
and withdraw the core bit.
In case of need, repeat the process or turn the core bit using the flat wrench.
Please note: Switch off the PRCD switch!
Optional: Dry drilling
Reinforced concrete only wet drilling!
Switch on the motor and the vacuum cleaner.
