Never Always
• Permit untrained people to handle, store, mount or use diamond saws • Observe the safety recommendations of the machine and • Mount or remove a diamond saw until the machine has been diamond saw manufacturer isolated from its power source • Exercise care when handling diamond saws • Mount a diamond saw that cannot be identified or one which • Keep the working area well lit, clean and tidy. Avoid slippery does not bear the correct marking and uneven floors and ice or snow • Mount a diamond saw on a machine running at a speed higher • Ensure other workers in the vicinity and passers-by are protected than the maximum operating speed of the diamond saw or from sparks and debris mount on a machine which does not bear its spindle speed • Store diamond saws on a full, flat surface, hung on a peg or in • Use diamond saws for cutting metal unless specifically designed to do so suitably constructed racks. Lightly lubricate to prevent rusting • Mount a diamond saw that has been dropped, damaged or • Visually check the diamond saw for damage such as core cracks incorrectly stored and missing or deformed segments • Apply force to fit the diamond saw on the mounting device, fit • Check that the diamond saw is suitable for the application and diamond saws with oversized bores or alter the bore size that the markings are intact and legible • Use drive pins or blotters to prevent slippage on hand-held • Use the correct tools at all times when mounting or removing a diamond saw diamond saws • Observe direction of run markings • Tighten flanges with excessive force or use a hammer or extension • Ensure mounting flanges are in matched pairs, clean, free from • Use damaged, distorted or dirty flanges and fastening screws burrs and undistorted • Use a machine which is not in good condition or one with a • Ensure an adequate coolant supply to both sides of the diamond damaged guard saw if cutting wet • Turn on the machine until the wheel guard has been re-fitted, • Ensure that the workpiece is secure and cannot move whilst being cut secured and adjusted correctly • Ensure guards are in position and correctly adjusted so that • Stand in the line of the diamond saw when starting the motor they do not foul the diamond saw after fitting or re-fitting a diamond saw • Rotate the diamond saw manually to ensure that it runs true • Start the diamond saw in contact with the workpiece or any other object and freely before turning on the power • Work from a ladder or in a position where you do not have full • Wear suitable protective clothing control of the machine • Observe the operating speed recommended by the diamond • Force the diamond saw to cut or allow it to overheat saw or machine manufacturer • Try to cut curves, turn in the cut or grind with a diamond saw • Run the diamond saw for at least 30 seconds at maximum • Allow the diamond saw to bounce or be trapped or pinched in the cut operating speed after mounting or re-mounting diamond saws • Press against the diamond saw surface to stop it or put down a • Ensure the diamond saw is running true and without vibration. machine until the diamond saw has stopped running Check frequently for undercutting or loss of tension • Leave the coolant running on a stationary diamond saw or leave • Allow the diamond saw to come to rest naturally after turning the diamond saw running on an unattended machine off the machine • Re-tip diamond saws which are not suitable for this • Ensure machine spindle speed is checked periodically using a tachometer • Use diamond saws for dry cutting on hand-held machines, unless • Ensure that the diamond saw is removed before transporting specifically authorised or storing portable and mobile machines
