SAFETY WARNINGS SPECIFIC FOR GRINDING
OPERATIONS
a) Use only wheel types that are recommended for
your power tool and the specifi c guard designed
for the selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
b) 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.
c) 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.
d) 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.
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 .
– Use clamps to support workpiece whenever practical.
Never hold a small workpiece in one hand and the tool
in the other hand while in use.
