Additional Safety Instructions - Hilti AG 4S-22 Mode D'emploi Original

▶ Do not use worn down wheels from larger power tools. A wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may burst.
▶ When using dual purpose wheels always use the correct guard for the application being performed.
Failure to use the correct guard may not provide the desired level of guarding, which could lead to serious
injury.
Additional safety warnings specific for cutting-off operations:
▶ Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or wheel breakage.
▶ Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible kickback may propel the spinning wheel and the
power tool directly at you.
▶ When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and
hold it motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off
wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
▶ Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
▶ Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on both sides of the wheel.
▶ Use extra caution when making a "pocket cut" into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
▶ Do not attempt to do curved cutting. Overstressing the wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage, which
can lead to serious injury.
Safety warnings specific for sanding operations:
▶ Use proper sized sanding disc paper. Follow manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending too far beyond the sanding pad presents a laceration
hazard and may cause snagging, tearing of the disc or kickback.
Safety warnings specific for polishing operations:
▶ Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck
away or trim any loose attachment strings. Loose and spinning attachment strings can entangle your
fingers or snag on the workpiece.
Safety warnings specific for wire brushing operations:
▶ Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not
overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate
light clothing and / or skin.
▶ If the use of a guard is specified for wire brushing, do not allow any interference of the wire wheel
or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal
forces.
