•
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.
•
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 and accidental contact with wheel.
•
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
•
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 cut-off disc 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, as
kickback may occur.
Investigate and take corrective action to eliminate the cause of wheel
binding.
•
Do not restart the cutting operation in the work piece. Let the wheel reach full speed and
carefully reenter the cut.
The cut-off disc may bind, walk up or kickback if the power tool is
restarted in the work piece.
•
Support panels or any oversized work piece to minimize the risk of cut-off disc 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 cut-off disc.
