          DO's

DIAMOND BLADES

ARE SAFE IF USED CORRECTLY

• Read the safety instructions provided by the abrasives and equipment supplier

• Store diamond blades in dry, frost-free conditions, avoid large temperature variations

• Ensure that the product is suitable for its purpose

• Handle, store and transport products with care

• Disconnect the power to the machine before fitting the diamond blade

• Examine all products before mounting and periodically during blade use for possible defects or damage (core flatness, fatigue cracks, undercutting, arbor damage…)

• Check that correct mounting devices are used and that they are clean, undistorted and free from burrs

• Ensure that work rests are properly adjusted and secure

• Always use a correctly designed and adjusted guard (on the blade and belts)

• Ensure that the workpiece is secure

• Wear appropriate personal protective equipment at all times

• Avoid clogging and uneven wear to ensure that the product is working efficiently

• Ensure accordance between product direction arrow / machine rotation

• Ensure that all machines using abrasives meet the requirements of the current european machinery directives-CE

• Be aware of the hazards likely during the use of abrasives and observe the recommended precautions to be taken:

  • Bodily contact with the abrasive product at operating speed

  • Injury resulting from product breakage during use

  • Grinding debris, sparks, fumes and dust generated by the grinding process

  • Noise

ARE DANGEROUS 

IF ABUSED

• Allow untrained people to use abrasives

• Use a product that is damaged or one which has been dropped

• Use a product if it cannot be properly identified

• Use a machine that is not in good working order or one with defective parts

• Force the abrasive onto the mounting device or modify the size of the mounting hole

• Exceed the maximum operating speed marked on the product

• Apply shock or excessive force to the product or let it overheat

• Use mounting flanges which are not clean and flat

• Tighten the mounting device excessively

• Start the machine until the guard is in place and fastened securely

• Continue to use a product if vibration occurs, true or replace it

• Grind on the part of the product which is not designed for the operation

• Start the machine with the workpiece in contact with the abrasive product

• Grind material for which the product is not designed

• Stop the abrasive by applying pressure to its surface, let it stop naturally

• Exceed permissible rotation speeds: refer to values engraved on product

• Use blades with missing segments or core cracks

• Use dry products marked for wet use

• Wear loose clothing, ties and jewellery

ALWAYS

• Wear eye protection EN166B

• Wear gloves EN 388 cat.2

• Wear hearing protection EN352

• Wear a respirator EN149

• Read the instructions

• Not to be used for side grinding

NEVER EXCEED - the maximum operating speeds:

• Handheld blades diam < or = to 230mm : 80 m/s

• Handheld blades diam > to 230 mm: 100 m/s

• Others: 63 m/s
