Safety Warnings Specific For Grinding Operations; General Safety Instructions For Grinders - Hitachi GP 3V Instrucciones De Manejo

English
d) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency
to snag the rotating accessory and cause loss of
control or kickback.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent kickback and loss of
control.
SAFETY WARNINGS SPECIFIC FOR
GRINDING 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) 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 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.
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 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;
– 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 flammable
substances;
– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, first 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.
