Projectile Hazards
WARNING
z
Be aware that failure of the workpiece or accessories, or even of the inserted tool itself can generate high-
velocity projectiles.
z
Always wear impact-resistant eye protection while operating this tool. The grade of protection required should
be assessed for each operation.
z
Ensure that the workpiece is securely fixed.
z
Ensure that the abrasive product is safely clamped to this tool.
z
Check that the maximum operating speed of the abrasive product, converted to revolutions per minute, is equal
to or greater than the rated speed of the spindle.
z
Ensure that the guard is in place, is in good condition and is correctly mounted; ensure that the guard is
regularly inspected. It is possible for internal grinding to not require a guard, provided the workpiece encloses
the abrasive product.
z
Check regularly that the speed of this tool is not higher than the speed marked on it. These speed checks shall
be carried out without the abrasive product mounted and in accordance with the instructions given by the
manufacturer.
z
Check that the flanges, as specified by the manufacturer, are used and are in good condition, e.g. free from
cracks and burrs, and are plane.
z
Check that the spindle and spindle threads are not damaged or worn.
z
Ensure that sparks and debris resulting from use do not create a hazard.

Disconnect this tool from the energy supply before changing the abrasive product and servicing.
Entanglement Hazards
WARNING
z
Choking, scalping and/or lacerations can occur if loose clothing, personal jewelry, neckwear, hair or gloves are
not kept away from the tool and its accessories.
Operating Hazards

If the abrasive product becomes jammed in a cut slot, shut off the grinder and ease the wheel free. Check that
the wheel is still correctly secured and not damaged before continuing the operation.
z
Grinding wheels and cutting-off wheels shall not be used for side grinding. (Exception: grinding wheels
designed for side grinding.) Grinders shall not be used over the maximum peripheral speed of an abrasive
product.

The operator shall pay attention and ensure that no bystanders are in the vicinity.
z
Personal protective equipment, such as suitable gloves, an apron and a helmet, shall be used.
