Manual Drilling
Dry drilling
Mount the appropriate adapter for dedusting.(refer to illustration at p. 22)
Insert the centering point so that the recesses in the
centering point latch on the catches of the working
spindle.
Fix the required dry drill bit on the working spindle.
Check for appropriate gear selection. Operate the ON/OFF switch and drill
until the segments are approximately 5 mm in the material. Remove the
centering point. Refix the drill bit to the existing groove and complete your
drilling.
Wet drilling
Open the ball valve and switch the tool on.
Hold the tool tight with both hands. Locate the tool slightly inclined. Once
the drill bit is in the material (approx. 1/8 to 1/4 of the circumference), bring
the tool into an angle of 90 degrees and continue drilling.
Take care that the drill bit is not out of line.
Advance the tool according to bit diameter and machine power. Observe
the LED in the handle.
If it lights red, reduce your pressing force.
In case the bit gets jammed, to not dry to release it by switching the
tool on and off.
This would cause premature wearing of the safety clutch.
Switch the tool off immediately and unfix the drill bit by turning to the left or
right using an appropriate open-end wrench. Cautiously pull the tool out of
the borehole.
Use of a water suction ring is mandatory for „overhead drilling“.
