▶ Avoid bringing the cut-off saw into contact with the working surface in the area indicated.
▶ 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.
▶ Apply pressure to the cut-off saw so that the cut-off wheel is pressed into the material slowly.
▶ 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.
▶ Always hold the cut-off saw firmly with both hands on the grips provided. Keep the grips dry, clean and
free from oil and grease.
▶ Make sure there is no-one in the working area and, in particular, in the direction in which the cut is to be
made. Keep everyone approx. 15 m away from your workplace.
6.3
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.
1. Cutting through thick workpieces should be accomplished, as far as possible, by making a several cuts.
Avoid making excessively deep cuts.
2. Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
6.4
Avoiding kickback
1. 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.
2. Take special care when inserting the cut-off wheel in an existing kerf.
6.5
Working with dust extraction module (accessory)
When dry-cutting with a dust extraction module, always wear a dust mask as an additional precaution!
Additionally, comply with and follow the national dust control regulations.
