▶ 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 or toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety warnings specific for grinding and abrasive cutting-off operations:
▶ Use only wheel types that are recommended 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 recommended 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. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may burst.
Additional safety warnings specific for abrasive 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 wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold
the power tool 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.
Safety warnings specific for sanding operations:
▶ Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of the disc or kickback.
2.3 Additional safety instructions
Personal safety
▶ Use the product only when it is in technically faultless condition.
▶ Never tamper with or modify the tool in any way.
▶ Always hold the power tool with both hands on the handles provided. Keep the handles clean and dry.
▶ Avoid touching rotating parts – risk of injury!
▶ Wear suitable protective glasses, a hard hat, ear protection, protective gloves and light respiratory
protection while using the power tool.
▶ Before beginning the work, check the hazard classification of the dust that will be produced. Use an
industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of
wood and concrete/masonry/stone containing quartz, minerals or metal may be harmful to health.
