• Observe the safety recommendations of 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! 

• Exercise care when handling abrasive wheels – they can easily be 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!

• Check that the wheel is the correct Specifications for the application 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 required!

• Make sure that workrests and workpiece clamping devices are secure and correctly positioned!

• 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 suitable protective clothing!

• Run the wheel for at least 30 seconds at operating speed after mounting or re-mounting. Stand out of the line of the wheel when turning on the machine!

• Dress bench grinding wheels regularly to keep the cutting surface in good condition!

• 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!

• Permit untrained people to handle, store, mount or use abrasives! 

• 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, damaged or incorrectly stored!

• Apply force to fit the wheel on the mounting device or alter the bore size or allow the wheel to overheat!

• 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!

• Turn on the machine until the wheel guard has been re-fitted, secured and adjusted correctly!

• Stand in the line of the grinding wheel when starting the motor after fitting or re-fitting a wheel!

• Start the wheel in contact with the workpiece or any other object!

•  Mount a wheel on a machine running at a speed higher than the maximum operating speed marked on the wheel!

• Work from a ladder or in a position where you do not have full control of the machine!

• Impact the work onto the wheel or the wheel onto the work!

• Grind on the side of a wheel unless it is specially designed for this application!

• 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 steep angle or try to cut with them!

• Dress the wheel with any device other than that recommended!

• Press against the wheel surface to stop it or put down a machine until the wheel has stopped running!

• Wear the wheel down to the mounting flanges!

• Allow the gap between the wheel and workrest to exceed 3 mm!
• Allow coolant to run on a stationary wheel or leave the wheel running on an unattended machine!
