WARNING!
In order to work optimally with this tool, the following safety instructions must be observed:
▶ Always hold the tool with both hands on the grips provided. Keep the grips dry, clean and free from oil
and grease.
▶ Before beginning the work, or if the disc has inadvertently come into contact with an obstacle (e.g. a
concealed object), check the cutting disc and guard immediately for possible damage.
▶ Check that no persons are present in the working area and, in particular, in the direction in which the cut
is to be made. Keep other persons approx. 15 m away from your workplace.
▶ Guide the tool smoothly and do not apply lateral pressure to the cutting disc.
▶ Avoid hazardous operating positions.
▶ Always bring the cutting disc into contact with the workpiece at right angles. Do not attempt to alter the
line of cut by applying lateral pressure or by bending the cutting disc while cutting is in progress.
▶ Secure the workpiece. Use clamps or a vice to hold the workpiece in position. The workpiece is thus
held more securely than by hand and both hands remain free to operate the tool.
▶ Clamp round workpieces so that they cannot rotate.
▶ Do not cut several workpieces at the same time. Cut them one after the other.
▶ Secure the workpiece and the part to be cut off in order to prevent uncontrolled movement.
▶ Always apply full throttle when cutting.
Avoiding sticking / stalling of the cutting disc
WARNING
Risk of bruising or other injuries. Sticking / stalling of the cutting disc in the kerf may cause the saw
to be pulled forward, to climb or cause kickback.
▶ Take care to avoid sticking / stalling of the cutting disc while cutting.
Reasons for the cutting disc sticking / stalling:
• The cut is too deep.
• The kerf becomes narrower (e.g. when cutting pipes or slabs).
• The cutting disc is tilted.
• An unsuitable cutting disc is used (the cutting disc becomes clogged).
• The cutting disc is inserted too quickly in an existing kerf.
Hazardous situations that may be caused depending on the working position and sticking / stalling
• 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.
