Manual Drilling
Fix the required dry drill bit on the working spindle.
Always deactivate the soft impact to start drilling!
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. To drill in concrete, activate the soft impact.
Refix the drill bit to the existing groove and complete your 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.
Diamond drill bits with a 1 ¼" UNC female thread and R ½" male thread can
be screwed directly onto the working spindle.
Use only appropriate drill bits for the material to be drilled in. You can
protect your tool by using only well balanced drill bits without deformation.
Make sure that the diamond segments have sufficient cutting clearance
towards the bit body.
Insert the centering point so that the recesses in the
centering point latch on the catches of the working
spindle.
