6.1 Cutting techniques
Avoiding kickback
There is a risk of kickback if the cut-off saw comes into contact with the working surface in the area indicated.
▶ Avoid bringing the cut-off saw into contact with the working surface in the area indicated.
▶ Always bring the cut-off wheel into contact with the workpiece from above. Allow the cut-off wheel to
contact the workpiece only at a point below its rotational axis.
▶ Take special care when inserting the cut-off wheel in an existing kerf.
Avoiding stalling
CAUTION
Risk of cut-off wheel breakage or kickback. Application of excessive pressure causes distortion of the
cut-off wheel. Sticking or stalling of the cut-off wheel increases the probability of kickback or cut-off wheel
breakage.
▶ Avoid applying excessive pressure when cutting and don't allow the cut-off wheel to stick and stall.
▶ Don't attempt to make an excessively deep cut.
▶ When cutting a thick workpiece, increase the depth of the kerf in steps. Avoid excessively deep cuts.
▶ Allow the cut-off saw to reach full speed before starting the cut.
▶ Bring the cut-off wheel into contact with the workpiece at right angles and below the axis of rotation.
▶ Ease the cut-off wheel slowly into the workpiece in a back-and-forth movement, without applying
excessive pressure.
▶ Apply moderate pressure, adjusting the rate of advance to suit the material being cut.
A decrease in the rate of cutting progress may be an indication of blunt/dull ("polished") diamond
segments. The diamond segments can be resharpened by making a few cuts in an abrasive
material (Hilti sharpening plate or sand-lime block).
▶ Guide the cut-off saw smoothly and without applying lateral pressure to the cut-off wheel.
