Eibenstock EHD 2002 S Originalbetriebsanleitung Seite 17

Convenient for the EHD 2002 S we offer a dust exhaust, which is enabling
the direct use of drill bits with 1¼" thread connection.
As a suitable wet/dry deduster, our (category M) is available as add-on. The
use of a dedusting system is also a prerequisite for optimal cutting.
Insert the centering point on the working spindle. Fix the required dry drill bit
on the working spindle. 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.
Advance the tool according to bit diameter and machine power.
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 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.
Changing Drill Bits
When you use or sharpen the machine, it might heat up enormously.
You could burn your hands or get cut or ripped by the segments.
Therefore, always use protective gloves when changing the drill bit.
The drilling spindle has a right-hand thread.
To ease screwing on and off, always use a SW 24 open-end wrench at the
drilling spindle.
Never use a hammer, because this may damage both the drill bit and the
tool.
Overload Protection
To protect the user, motor and drill bit, the EHD 2002 S is equipped with a
mechanical, electrical and thermal overload protection.
Mechanical: In the event of a sudden jamming of the drill bit, the
machine's kickback is limited to a reaction torque
controllable by the operator by means of a slip clutch.
Electrical: In case of overload due to too large feed force, the electronic
will cut OFF the machine. After discharge and switching ON
you can continue drilling again.
