: Cut deeper into the parting cut with 
uniform back-and-forth movements, 
starting at the top and moving out 
towards the sides.  Advance the 
cutting wheel along the guiding 
groove at full cutting depth.  Always 
reposition the cutting wheel afresh, 
taking care not to wedge it if the 
cutting direction has to be corrected 
slightly.  If necessary, leave small 
ridges of uncut material to hold the 
severed part in position.  These 
ridges can subsequently be broken 
through.
Economic benefit is improved and 
premature wear can be avoided by 
choosing and using the correct 
composite resin cutting wheel.  The 
short name (e.g. “asphalt“, “concrete“)
– on the label and
– on the packaging (table with 
recommended uses)
can help to ensure the correct choice.
