MANDATORY SAFETY INSTRUCTIONS. (The following instructions must be observed together with those in Section 1).
DAngEr! The use of a damaged wheel is dangerous and may cause damage or personal injury.
WArnIng! Ensure grinder is unplugged from the mains power supply before attempting to change grinding wheels.
only persons qualified under the "Abrasive Wheels regulations" and holding a current grinding wheel certificate are to
change grinding wheels.
Grinding wheels used with this machine shall be of an adequate speed rating and of the correct composition for the material to be ground.
Ensure the maximum speed specification of the wheel is higher than that indicated on the machine data plate.
Before use check that grinding wheels are secure, are not worn or damaged and have no fissures or cracks. Replace faulty wheels immediately.
Ensure replacement wheel is not damaged in any way - cracks, deformations or splinters etc. Also check the mounting flanges to ensure
that these are not deformed, burred or chipped. Damaged items must not be used as they can produce high stresses in the wheel which
may cause it to break. Do noT over tighten a wheel. Never tamper with a wheel in order to adapt it to a different size drive shaft.
Once mounted on the grinder test the wheel(s) before use by facing the grinder in a safe direction (point away from yourself, others and
