Place the machine with the front roll (cover) on the surface to be worked.
Switch on the machine and slowly lower and plunge the cutting unit into the
material.
Guide the machine with both handles, applying moderate feed, suited to the
material being worked.
The wall chaser must always work in an up-grinding motion (sliding
cut). Otherwise, the danger exists of it being pushed uncontrolled out
of the cut.
Remove the remaining fin of the material with a break-out tool or a chiselling
hammer. Curved cuts are not possible, as the diamond cutting discs could
jam in the material.
When breaking through walls, e. g. with a rotary hammer, most of the
chipping-off of the surface material can be avoided by first cutting in a slot
with maximum cutting depth.
For cutting expecially hard material, e. g. concrete with high pebble content,
the diamond cutting disc can overheat and become damaged as a result.
This is clearly indicated by circular sparking, rotating with the diamond
cutting disc.
In this case, interrupt the cutting process and allow the diamond cutting disc
to cool by running the machine for a short time with no load.
Noticeable decreasing work progress and circular sparking are indications of
a blunt diamond cutting disc. Briefly cutting into abrasive material (e. g. lime-
sand brick or the EIBENSTOCK-diamond-sharpening-stone) can re-sharpen
the disc again.
Pre-selection of the Cutting Depth

For adjusting the cutting depth open the
locking lever.
By turning the protection cover adjust the
required cutting depth on the scale and close
the locking lever again.
The locking lever has to be locked firmly on
working always.
