Wheels for which the power tool was not designed cannot
be adequately guarded and are unsafe.
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 operator.
The guard helps to protect operator from broken wheel
fragments and accidental contact with wheel.
c) 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.
d) Always use undamaged wheel fl anges that are of
correct size and shape for your selected wheel.
Proper wheel fl anges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be diff erent from grinding wheel fl anges.
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 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 blinding 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.
GENERAL SAFETY INSTRUCTIONS FOR
GRINDERS
Check that speed marked on the wheel is equal to or
greater than the rated speed of the grinder;
Ensure that the wheel dimensions are compatible with
the grinder;
Abrasive wheels shall be stored and handled with care in
accordance with manufacturer's instructions;
Inspect the grinding wheel before use, do not use
chipped, cracked or otherwise defective products;
Ensure that mounted wheels and points are fi tted in
accordance with the manufacturer's instructions;
Ensure that blotters are used when they are provided
with the bonded abrasive product and when they are
required;
Ensure that the abrasive product is correctly mounted
and tightened before use and run the tool at no-load for
30 seconds in a safe position, stop immediately if there
is considerable vibration or if other defects are detected.
If this condition occurs, check the machine to determine
the cause;
If a guard is equipped with the tool never use the tool
without such a guard;
Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
For tools intended to be fi tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;
Check that the work piece is properly supported;
Do not use cutting off wheel for side grinding;
Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite fl ammable
substances;
Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become necessary
to clear dust, fi rst disconnect the tool from the mains
supply (use non metallic objects) and avoid damaging
internal parts;
Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves, helmet
and apron should be worn;
Pay attention to the wheel that continues to rotate after
the tool is switched off .
