210 / Coated Abrasives www.youtube.com/NortonAbrasivesEMEA SAFETY ADVICE All coated abrasives should be handled carefully. Damage can be caused by mishandling, which should be avoided. Coated abrasives should be stored in dry, frost free conditions. They should be kept away from heat sources, cold, damp walls, doors or windows and should not be in direct contact with the floor. Temperatures and humidity should be between 18°C and 22°C and 45%-65% relative humidity. Coated abrasives should not be exposed to direct sunlight. Products should be kept in their original packaging until immediately before use. Once unpacked, they should be stored in a way which avoids distortion. Temperature and humidity are the two most important climatic factors influencing coated abrasive performance. Backings and adhesives are sensitive to climatic changes and will gain or lose moisture according to the relative humidity of their surroundings. Excessive humidity may cause a softening of some types of adhesive bonds so that the product quickly fills and clogs, or loses its grain during use. Excessive dryness may cause brittleness, reduced flexibility, and distortion of product shapes. As moisture in the coated abrasive product increases or decreases, dimensional changes can occur. When the backing changes more than the adhesive bond, it causes cupping. High and low humidity can cause concave and convex cupping respectively. The newer synthetic-backed belts are not affected by moisture. Broad temperature swings will not permanently harm these products either, but cold temperatures will cause a “cold set” condition. Consequently, these products should be allowed to come to room temperature before use. • Keep products in original packages. These packages facilitate handling and can be stacked in the most practical and convenient manner. • Bulk rolls should not be allowed to stand on edge after they have been unpacked. Store flat on shelves or pallets. • Narrow belts which have been removed from the carton should be rolled up and stored on edge on a clean shelf. Belts may be draped over a large cylinder, such as a brake drum, or flanged hanger of the type used for a garden hose. Never hang a belt from a nail – the backing will crease and the abrasive belt might crack. • Wide belts should be hung over a tube of at least 100mm diameter. Centre the belt joint over the tube and add a light weight (such as old packaging tubes) to the bottom loop of the belt to aid in removing set. • Condition for 24 hours prior to use. • For maximum product efficiency, precondition coated abrasive products in a chamber of controlled temperature and humidity before use. TRANSPORT & STORAGE KEEP PRODUCTS IN ORIGINAL PACKAGING STORE BULK ROLLS FLAT STORE BELTS PROPERLY KEEP AWAY FROM HEAT / COLD SOURCES PRE-CONDITION BEFORE USE SAFETY ADVICE Safety instructions provided by the machine manufacturers must be followed. Where fitted, all guards, covers and hoods must be in place on the machine during grinding, and should not be modified in any way. Abrasives should not be used near inflammable material or in an environment where there is a risk of explosion. Sparks should be directed away from the face and body, if possible, towards the floor. Dust extraction equipment must be used whenever it is available. The instructions for use given by the abrasive manufacturer must be followed e.g., ‘Not to be used without a support’, or ‘Not to be used for wet grinding’. The workpiece must be firmly fixed before grinding starts. Check all abrasives visually before use and make certain that the product is suitable for the application. No modifications should be made to abrasive products after delivery. When using a portable grinder always switch it off and allow the spindle to stop completely before putting the tool down.
