Care And Maintenance; Maintenance Table - Hilti DSH 600-X Mode D'emploi

▶ 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 gasoline-powered saw smoothly and without applying lateral pressure to the cut-off wheel.
▶ Always hold the gasoline-powered 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.
6.5 Avoiding stalling
If the cut-off wheel binds, the product tends to pull away from the operator.
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.
▶ Cutting through thick workpieces should be accomplished, as far as possible, by making a several cuts.
▶ Always cut only one workpiece at a time.
▶ Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
6.6 Avoiding kickback
Kickback is a sudden reaction to a pinched or snagged rotating wheel. Snagging or binding brings the
rotating accessory tool to an abrupt stop. This causes the product to accelerate at the point of binding, in
the direction opposite to the accessory tool's direction of rotation.
For example, if a cut-off wheel is snagged or pinched by the workpiece, the edge of the cut-off wheel entering
the pinch point can dig into the surface of the material causing the cut-off wheel to climb out or kick back.
If this happens the cut-off wheel moves toward or away from the operator. The further forward the cut-off
wheel binds, the higher the probability of a kickback. cut-off wheels can also break under these conditions.
A kickback is the result of product misuse and/or incorrect operating procedures or conditions. It can be
avoided by taking the proper precautions as described below. If the cut-off wheel binds when the product is
cutting in the direction of the ground, the product can jump forward in an uncontrolled manner. If the cut-off
wheel binds when the product is cutting vertically, for example in a wall, the product can jump upward in an
uncontrolled manner.
▶ Always bring the cut-off wheel into contact with the workpiece from above, with the throttle trigger fully
depressed.
▶ 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.
