does not light during idle run or at normal load. At overload,
it lights red. In that case the tool most be stress-relieved. In
case of longer non-observation of the rad indication, the
electronics will independently switch the tool off.
relieving is switching the tool off and on, the work can be
continued as normal.
Thermal:
In case of permanent overload, a thermocouple protects the
motor against destruction. In that case, the tool switches off
and can only be restarted after a certain cooling-down
period (approx. 2 minutes). The cooling-down time depends
on the temperature of the motor winding and ambient
temperature.
Safety Clutch
The slip clutch served for compensation of shocks and overload.
To keep its functionability, it should not slip for more than 2 seconds. In
case of excessive wearing, it can be replaced by an authorized service
centre.
Diamond drill bits with an 1/¼" UNC female thread ore an 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.
Changing Drill Bits
Attention!
The bits may have got hot due to use or sharpening. There is a danger
of burning ones hands or injuring oneself at the segments' edges.
When changing the drill bits, you should always wear protective
gloves
The drilling spindle has a right-hand thread.
To ease screwing on and off, always use a SW 32 open-end wrench at the
drilling spindle.
