b) The grinding surface of center 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) 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, accidental contact with wheel and
sparks that could ignite clothing.
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 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.
f) 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 fitted 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 s 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 fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length;
– Secure the workpiece and check that the workpiece
is properly supported. A workpiece clamped with
clamping devices or in a vice is held more securely
than by hand;

– 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 .
SPECIFIC SAFETY RULES AND SYMBOLS
1.
ALWAYS use proper guard with grinding wheel.
A guard protects operator from broken wheel
fragments.
2.
Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels
and other accessories running over rated speed can
fl y apart and cause injury.
3.
ALWAYS wear ear protectors when using the
tool for extended periods.
Prolonged exposure to high intensity
noise can cause hearing loss.
4.
Use only a depressed center wheel with a rated
capacity which is GREATER than 12,300/min.
Using any wheel a rated capacity LESS than
12,300/min and/or an incorrect sized wheel (see
SPECIFICATIONS at page 9) may result in wheel
breakage, flying wheel fragments, and resulting in
death or serious injury.
5.
NEVER touch moving parts.
NEVER place your hands, fingers or
other body parts near the tool's moving
parts.
6.
NEVER operate without all guards in place.
NEVER operate this tool without all guards or safety
features in place and in proper working order. If
maintenance or servicing requires the removal of a
guard or safety feature, be sure to replace the guard
or safety feature before resuming operation of the
tool.
7.
Use right tool.
Don't force small tool or attachment to do the job of a
heavy-duty tool.
Don't use tool for purpose not intended —for
example— don't use circular saw for cutting tree
limbs or logs.
