5.13 Working safely with the cutter

Conditions: Working on mineral materials

There is a risk of kickback if the cutting disc comes

into contact with the working surface in the area

indicated.

▶ Avoid bringing the cutting disc into contact with the working surface in the area indicated.

▶ Always bring the guide wheels into contact with the working surface / workpiece before starting the

cut.

▶ Allow the power tool to reach full speed before beginning cutting.

▶ Apply pressure to the power tool so that the cutting disc 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 power tool smoothly and do not apply lateral pressure to the cutting disc.

The diamond disc may overheat and suffer damage when cutting very hard mineral materials, e.g.

concrete with a high hard pebble content. A trail of sparks right round the circumference of the diamond

cutting disc is a sure indication of this.

▶ Should this occur, stop cutting and cool the diamond cutting disc by allowing the power tool to run

under no load.

Dust can be kept to a minimum when working by using a suitable vacuum cleaner. Use of a vacuum

cleaner also helps to cool the segments on the disc and thus reduces segment wear.

▶ The vacuum cleaner should be equipped with an antistatic suction hose in order to avoid electrostatic

effects.
