Use and Care Manual
20 English
• Pulling may occur when making horizontal cuts (e.g. in a floor). The saw may suddenly pull forwards,
possibly pulling it out of the operator’s hands.
• Climbing may occur when making vertical cuts (e.g. in a wall). The saw may suddenly pull upwards,
possibly pulling it out of the operator’s hands.
• Kickback may occur if the prohibited area of the disc is brought into contact with the workpiece.
Avoiding hazardous situations resulting from sticking / stalling of the cutting disc:
▶ Cutting through thick workpieces should be accomplished, as far as possible, by making several cuts.
Avoid making excessively deep cuts.
▶ Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
▶ Always bring the cutting disc into contact with the workpiece from above.
◁ Allow the cutting disc to contact the workpiece only at a point below its rotational axis.
▶ Be particularly cautious when inserting the cutting disc in an existing kerf.
▶ Take care to avoid tilting the cutting disc to the side.
