▶ Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.
▶ Do not attach a saw chain woodcarving blade, segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control.
Safety warnings specific for grinding and cutting-off operations:
▶ Use only wheel types that are specified for your power tool and the specific guard designed for
the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded
and are unsafe.
▶ The grinding surface of centre depressed wheels must be mounted below the plane of the guard
lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately
protected.
▶ The guard must be securely attached to the power tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the operator. The guard helps to protect the operator from
broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
▶ Wheels must be used only for specified applications. For example: do not grind with the side of
cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
▶ Always use undamaged wheel flanges that are of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel flanges.
▶ 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 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.
