Take care that the segments jut out sufficiently against the tube.
It is useful to apply some water resistant grease to the thread of your tool so it can be taken off again
more easily.
Take care that the radial run out at the diamond segments of the core bits is not more than
1 mm.
Only use suitable wrenches for changing the core bit. Thereby hold the drilling spindle with another
wrench.
Never use a hammer or something similar to open the core bit. If necessary elongate
the wrench.
5.2 General
For dry drilling, mount the suction hose on the dust extraction system (3) and switch on the vacuum
cleaner.
For exact drilling, the piercing spike no. AS13 can be inserted into the drilling spindle. Remove the
piercing spike after drilling - max. 10 mm deep.
For dry drilling, be sure to use powerful dust extraction, where the filter will not clog up or be
shaken off by appropriate precautions.
Dry drilling is only possible in absolutely dry material. Damp material can not be drilled dry -
risk of clogging.
5.3 Soft beat and dust extraction
By using the rotary handle (2) on the side of the machine, the soft beat can be easily switched on or
off. The soft beat accelerates the work progress in hard materials and supports the transport of the
drilling dust for dust extraction.
The efficient dust extraction system (3) ensures dust-free work. The dust extractor is connected to the
machine by an easy-to-remove securing spring (4).
5.4 Drilling - directed by a drill rig
Since the drill stand is not included in the delivery, we merely want to point out some important things
you should note when using the machine.
Please observe the special instructions for the drill rig.
Kinds for fixing the rig
Fixing the stand using dowels, by vacuum and by a brace.
The mainly applied method to fix the stand is given by using dowels. It is preferable to use metal
dowels. The diameter must be at least 16 mm.
When fixing the stand by vacuum, take care that the vacuum is sufficient high.
Make sure the seals are not worn out.
Please take care that the rig is really fixed solid and stable, if by the aid of the adjusting screws at the
base plate of the rig the vacuum seal is released.
5.5 Drilling - hand held
Open the ball valve and start the machine.
Hold the core drill as rigidly as possible.
Touch the surface you want to work on with the core bit in a slight angle (of about 30 to the axe) or
use the start drilling aid (special accessories).
After the bit has worked its way into the object for about 1/8-1/4 of the circle's circumference, turn the
core drill up into a right-angled position, using sufficient initial pressure.
Formula: drilling diameter in mm x 4 = contact power in N.
Use especially for bigger core bits a drilling-start aid which helps to keep track for the first few
millimeters. This can simply be a wooden plate with a recess in it in the shape of a triangle in which
the core bit can be guided.
Take special care that the core bit is directed in a straight way in the drilled hole so it does not block.
