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 reducing 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.
Additional Safety Warnings Specific for Abrasive Cutting-Off operation:
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 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 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 protruding wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
Additional safety warnings – Grinder
- Hold power tool by insulated gripping surfaces, when performing an operation
where the cutting acessory may contact hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
Additional safety hits:
- Your hand must hold on the handle when you are working. Loss of control can cause
personal injury.
- Make sure that the wheel dimensions are compatible with the grinder.
- Grinding wheels shall be stored and handled with care in according with the
manufacturer's instruction.
- Inspect the grinding wheel before use do not use chipped, cracked or otherwise
defective products.
- Make sure that mounted wheels and points are fitted in accordance with the
manufacturer's instruction.
- Make sure that the abrasive product is correctly mounted and tightened before use
