d) 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.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such
blades create frequent kickback and loss of control.
Additional safety instructions for grinding and cutting-off operations
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:
a) 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.
b) 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.
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. 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:
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 work-piece. 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 work-piece.
e) Support panels or any oversized work-piece to minimize the risk of wheel
pinching and kickback. Large work-pieces tend to sag under their own weight.
Supports must be placed under the work-piece near the line of cut and near
the edge of the work-piece 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.
