• The grinding surface of centre
depressed wheels must be
mounted below the plane of
the guard lip. An improperly moun-
ted wheel that projects through the
plane of the guard lip cannot be ad-
equately 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 frag-
ments, accidental contact with wheel
and sparks that could ignite clothing.
• Wheels must be used only for
specified applications. For ex-
ample: 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. A wheel
intended for larger power tool is not
suitable for the higher speed of a smal-
ler tool and may burst.
• When using dual purpose
wheels always use the correct
guard for the application being
performed. Failure to use the cor-
rect guard may not provide the desired
level of guarding, which could lead to
serious injury.
Additional safety warnings
specific for cutting-off operations
• Do not “jam” the cut-off wheel
or apply excessive pressure. Do
not attempt to make an excess-
ive depth of cut. Overstressing the
wheel increases the loading and sus-
ceptibility 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 rotat-
ing 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 the wheel is binding or
when interrupting a cut for any
reason, switch off the power
tool and hold it motionless un-
til the wheel comes to a com-
plete stop. Never attempt to
remove the cut-off wheel from
the cut while the wheel is in mo-
tion otherwise kickback may
occur. Investigate and take corrective
action to eliminate the cause of wheel
binding.
• Do not restart the cutting op-
eration 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 work-
piece.
• Support panels or any over-
sized 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
