Read the safety instructions provided by the machine and wheel manufacturer
Keep the working area well lit, clean, tidy and free from obstructions
Avoid slippery and uneven floors and do not work on ice or snow
Ensure other workers in the vicinity and passers-by are protected from sparks and debris
Handle wheels with great care, grinding wheels are very fragile and can be easily damaged
Store wheels in dry and frost-free conditions avoiding wide variations in temperature and the risk of damage
Visually check the wheel for damage or defects and conduct a ring test before mounting
Ensure that the wheel is suitable for its intended use and that the markings are intact and legible
Use the correct tools when mounting or removing a wheel
Ensure mounting flanges are in matched pairs, clean, free from burrs and undistorted
Use blotters to prevent wheel slippage where supplied by the wheel manufacturer
Ensure that workrests and clamping devices are secure and properly adjusted
Ensure guards are in position and correctly adjusted so that they do not foul the wheel
Rotate the wheel manually to ensure that it runs true and freely before turning on the power
Wear the appropriate personal protective equipment at all times
Conduct a trial run, standing clear of the machine before using the wheel
Dress wheel frequently to remove uneven wear and ensure that it is cutting correctly
Allow the wheel to come to rest naturally after turning off the machine
Ensure the workpiece is properly supported or clamped so that it cannot move during grinding or cutting
Spin out residual coolant from the wheel before turning off the machine
Report wheel breakages, keeping hold of all of the debris for examination
Ensure machine spindle speed is checked periodically using a tachometer
Ensure that damaged or defective wheels and worn-out wheels are destroyed to prevent them from being used
Ensure that the wheel is removed before transporting or storing portable machines |
Allow untrained persons to handle, store, mount or use abrasive wheels
Mount or remove a wheel until the machine has been isolated from its power source
Mount a wheel that cannot be identified or one which does not bear the correct marking
Mount a wheel on a machine which does not display its spindle speed
Mount a wheel which is beyond its marked expiry date or recommended shelf life
Mount a wheel that has been dropped or damaged or one that has not been stored correctly
Force the wheel to fit on the mounting device or modify the bore size
Tighten flanges with excessive force or use a hammer or extension
Use damaged, distorted or dirty flanges and fastening screws
Use a machine which is not in good condition or one with a damaged guard
Start the machine until the wheel guard is in place and fastened securely
Stand directly in front of a grinding wheel whenever the machine is started after mounting a wheel
Start the wheel in contact with the workpiece or any other object
Exceed the maximum operating speed marked on the wheel
Work from a ladder or in a position where you do not have full controlof the machine
Apply excessive shock or pressure to the wheel or allow it to overheat
Grind on the side of a wheel which is not designed for the operation
Apply side pressure by trying to cut curves or by grinding surfaces with cutting-off wheels
Allow the wheel to bounce or be trapped or pinched in the cut
Use type 27 depressed centre grinding wheels at a shallow angle or try to cut with them
Dress the wheel with any device other than that recommended
Stop the wheel by applying force to the wheel or put down a machine until the wheel has stopped running
Wear the wheel down to the mounting flanges or beyond the correct adjustment of the workrests
Allow coolant to run on a stationary wheel or leave the wheel running on an unattended machine |

Read the safety instructions provided by the machine and saw manufacturer. Always handle saws with care
Keep the working area well lit, clean and tidy. Avoid slippery and uneven floors and ice or snow
Ensure other workers in the vicinity and passers-by are protected from sparks and debris
Store saws in dry and frost-free conditions avoiding wide variations in temperature and the risk of damage
Store on a full, flat surface, hung on a peg or in suitably constructed racks.Lightly lubricate to prevent rusting
Visually check the saw for damage such as core cracks and missing or deformed segments
Ensure that the saw is suitable for its intended use and that the markings are intact and legible.
Use the correct tools at all times when mounting or removing a saw. Observe direction of run markings
Ensure mounting flanges are in matched pairs, clean, free from burrs and undistorted
Ensure an adequate coolant supply to both sides of the saw if cutting wet.
Use laser-welded blades for dry cutting on hand-held machines
Ensure that the workpiece is secure and cannot move whilst being cut
Ensure guards are in position and correctly adjusted so that they do not foul the saw
Rotate the saw manually to ensure that it runs true and freely before turning on the power
Wear the appropriate personal protective equipment at all times
Observe the operating speed recommended by the saw or machine manufacturer
Run the saw for at least 30 seconds at maximum operating speed after mounting or re-mounting saws
Ensure the saw is running true and without vibration. Check frequently for undercutting or loss of tension
Allow the saw to come to rest naturally after turning off the machine
Ensure machine spindle speed is checked periodically using a tachometer
Ensure that the saw is removed before transporting or storing portable and mobile machines |
Allow untrained persons to handle, store, mount or use diamond saws
Mount or remove a saw until the machine has been isolated from its power source
Mount a saw that cannot be identified or one which does not bear the correct marking
Exceed the saw’s maximum operating speed or mount on a machine which does not bear its spindle speed
Use diamond saws for cutting metal unless specifically designed to do so
Mount a saw that has been dropped or damaged or one that has not been stored correctly
Force the saw to fit on the mounting device, fit saws with oversized bores or modify the bore size
Use drive pins or blotters to prevent slippage on hand-held diamond-saws
Tighten flanges with excessive force or use a hammer or extension
Use damaged, distorted or dirty flanges and fastening screws
Use a machine which is not in good condition or one with a damaged guard
Start the machine until the wheel guard is in place and fastened securely
Stand directly in front of a saw whenever the machine is started after mounting a saw
Start the wheel in contact with the workpiece or any other object
Work from a ladder or in a position where you do not have full controlof the machine
Apply excessive shock or force to the saw or allow it to overheat
Try to cut curves, turn in the cut or grind with a diamond saw
Allow the saw to bounce or be trapped or pinched in the cut
Stop the saw by applying force to its surface or put down a machine until the saw has stopped running
Leave the coolant running on a stationary saw or leave the saw running on an unattended machine
Re-tip saws which are not suitable for this. Only use approved companies conforming to EN13236 |
