SAFETY INFORMATION
• 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 operator from broken wheel fragments, accidental contact with 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 instructions for cutting-off operations
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.
Additional safety instructions for polishing operations
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.
Additional Safety Warnings
• Do no use standard flat wheels for face grinding. Side forces applied to these wheels may
cause them to shatter or burst.
