8 Instructions for Use
The wall chaser HCE150 is equipped with a lock-off button against
unintentional switch-on.
Switching-on: push the on/off switch
forward (1) and then down (2)
Switching-off: release the on/off switch
Exercise caution when cutting slots in supporting walls; see section "Information on
structural calculations".
Do not strain the machine so heavily that it comes to a standstill.
Only use the wall chaser for dry cutting.
Adjust the cutting depth see section "Pre-selection the Cutting Depth". To compensate inaccuracies
that occur when breaking away the fin, the cutting depth must be set approx. 3 mm deeper than the
requested slot depth.
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
with.
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 a diamond-sharpening-
stone) can re-sharpen the disc again.
