Safety warnings specific for grinding and 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 the 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)
Use only the specific guard designed for the selected wheel. 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 and accidental contact with the wheel.
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. Wheels intended for larger power tools
are not suitable for the higher speed of a smaller tool and may burst.
Additional safety instructions for 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
kick-back may occur. Investigate and take corrective action to eliminate the cause of wheel
binding.
d)
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in
the workpiece.
e)
Support panels or any oversized workpiece to minimise 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)
Take 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.
Safety Warnings Specific for Sanding Operations.
a)
Do not use excessively oversized sanding disc paper. Follow manufacturers
recommendations when selecting sanding paper. Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.
Safety Warnings Specific for Wire Brushing Operations.
a)
Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not
overstress the wires by applying excessive load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b)
If the use of a guard is recommended for wire brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work
load and centrifugal forces.
WARNING! This electrical equipment creates an electromagnetic field during its
operation. Such a field can interfere with active or passive implants under certain
circumstances. To reduce the risk of serious or lethal injury, we recommend that
persons with implants consult their physician or implant manufacturer and ask
whether they can use this equipment.
