b) 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 op-
erator. The guard helps to protect operator from
broken wheel fragments, accidental contact with
wheel and sparks that could ignite clothing.
c) Wheels must be used only for recommended ap-
plications. For example: do not grind with the side
of cut-off wheel.Abrasive cut-off wheels are inten-
ded for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus redu-
cing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel
flanges.
e) 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.
5.5 Additional safety warnings specific for abrasive
cutting-off operations
a) Do not ²jam² 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
reenter the cut. The wheel may bind, walk up or kick-
back 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 pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.

The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Material
containing asbestos must only be treated by special-
ists. Where the use of a dust extraction device is
possible it shall be used. To achieve a high level
of dust collection, use a suitable vacuum cleaner
