The protection must be solidly fixed to the tool and placed in the safest
position possible so as to minimise the potential risk of contact between the
operator and cutting/grinding wheel. The protection is designed to protect
operators from the ejection of fragments in case of breakage and from accidental
contacts with the grinding wheel.
Cutting/grinding wheels must be used for the recommended applications
only. For example do not use the cutting side of the wheel for grinding
operations. Abrasive cutting wheels may break because they are designed to be
used for peripheral grinding operations and for the application of lateral forces.
Always use the cutting/grinding wheels with undamaged flanges and verify
that their shape and dimensions are appropriate for the selected
cutting/grinding wheel. The purpose of flanges is to support the cutting/grinding
wheel and reduce the potential risk of breakage. Flanges forcutting wheels may be
different from those of grinding wheels.
Do not use grinding/cutting wheels that have been fitted on larger tools.
These cutting/grinding wheels are unsuitable because of their higher speed as
compared to that of smaller tools and could therefore cause explosions.
ADDITIONAL SAFETY WARNINGS FOR ABRASIVECUTTING OPERATIONS
Do not “stall” the cutting wheel or apply an excessive pressure. Do not
attempt to increase the cutting depth. The application of a high pressure on the
cutting wheel increases the load and the risk of torsion and bending during
cutting, with the consequent risk of rebound forces or breakage.
Do not stand in line with the cutting/grinding wheel or behind it while it is
rotating. When the cutting/grinding wheel moves away from the operator’s body
during operation, the rebound force may push the revolving cutting/grinding wheel
and the tool towards the operator.
If the cutting/grinding wheel bends or the cutting operations stops for any
reason, disconnect the tool from the power supply and keep it still until the
cutting/grinding wheel has come to a full stop. Do not attempt to remove the
cutting wheel while it is moving because this could produce a rebound force.
Identify the cause of the problem and perform the necessary corrective actions to
prevent the problem from reoccurring.
Do not resume the cutting operation. Resume the cutting operation only when
the cutting wheel has reached its maximum speed. The cutting wheel may stall,
lift or produce a rebound force if the tool is restarted when the work piece is
present.
Always use appropriate supports for panels or large work pieces in order to
minimisethe risk of interlocking and rebound forces. Large work pieces tend to
bend because of their weight. Supports must therefore be placed under the work
piece, close to the cuttingline and to the edge of the work piece on both sides.
Pay particular attention when cutting “pockets” on existing walls or other
areas with limited visibility. The projecting cutting wheel may cut gas or water
pipes, electrical cables or other objects and thus produce a rebound force.
SPECIFIC SAFETY WARNINGS FOR METAL BRUSHING:
Keep in mind that the brush, even during normal operation, emits metal
bristles. Do not apply excessive force to the metal wires, by applying
excessive force to the brush. The metal bristles can easily penetrate light
clothing and/or hair.
If use of protection for the metal brushing is recommended, do not allow any
interference of the disc to the metal wires or of the brush with the protection.
The disc with metal wires or the brush can expand in diameter due to the work
load and centrifugal forces.
FURTHER HAZARD WARNINGS
Avoid having dust accumulated on the work station. The dust can easily ignite.
A work piece can be safely locked in position only using an appropriate
tightening device or a screw clamp and not just holding it with your hand.
Adjust the protective earmuffs so as to impede a trail of sparks in the
direction of the operator. Do not touch the rough and cut grinding wheels
before they are cooled. Activate the locking key of the spindle only when
thespindle is stopped. Otherwise, the electrical tool may suffer damages.
