b) The grinding surface of centre depressed discs must be mounted below the plane of the guard
lip. An improperly mounted grinding disc that projects through the plane of the guard lip cannot be
adequately protected.
c) 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.
d) 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.
e) 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.
f) Do not use worn down wheels from larger power tools. Wheels intended for larger power tools are not
suitable for the higher speed of a smaller tool and may burst.

Additional Safety Warnings Specific for Abrasive Cutting-Off Operations:
a) 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.
b) 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.
c) 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.
d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
e) 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.
f) 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.
3.5
Safety Warnings Specific for Sanding
Operations:
a) Do not use excessively oversized sanding disc paper. Follow manufacturer's 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.
3.6
Only for MINI-PLUS & QUICK-STEP FINISHER
Safety Warnings Specific for Polishing Operations:
a) 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.
3.7
Safety Warnings Specific for Wire Brushing Operations:
a) 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.
b) If the use of a guard is recommended 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.
3.8
Additional Safety Instructions: WARNING
– Always wear protective goggles.
Use only accessories that are covered by at least 3.4 mm by the safety guard.
Use elastic cushioning layers if they have been supplied with the grinding media and
if required.
Observe the specifications of the tool or accessory manufacturer! Protect the discs
from grease or impacts!
