RECOMMENDATIONS : Personal Protection

  • Always use protective glasses and / or face shields as recommended in ANSI Standard Z87.1.
  • Use appropriate body protection such as leather gloves, safety shoes and aprons.
  • Never reach or permit clothing, hair, jewellery or other loose article to get between rotating wheel and machine or work piece fixture.
  • Observe all safety recommendations of machine manufacturer and your own Safety Engineering Department.
  • Never stand directly in front of a wheel when machine is started.
  • Do not leave machine running unattended.


  • Make sure operating speed established for machine does not exceed the maximum free operating speed marked on wheel or label.
  • Always use a properly designed safety guard. Never start machine until safety guard is in place. See machine manufacturer’s recommendations.
  • Use dust collection system with equipment.
  • Periodically check the machinery and mounting hardware to make sure they are in good operating condition. Repair or replace damaged machinery and mounting hardware.
  • Use proper mounting hardware. Wheel flanges must be a minimum of 1/3 the diameter of the wheel and of equal size. Never use wheel flanges that are burred or distorted. Use of such flanges can cause uneven, non-uniform pressure on wheels when tightened.
  • Tighten shaft nut only as tight as is necessary to hold wheel firmly and avoid slippage. Excessive clamping stress is likely to damage the wheels.


  • Always handle and store wheels in a careful manner. Never use a wheel that has been dropped or damaged.
  • Visually inspect all wheels prior to installation on equipment for defects or damage.
  • Make sure arbor hole is correct for shaft being used. Never force a wheel on to the machine or alter the size of the arbor hole. If bushings are used, be sure both the O.D. and I.D. of the bushing are the correct size for the wheel and the shaft.
  • Carefully mount wheel on equipment. Use recommended wheel flanges only. NEVER USE WHEEL FLANGES LESS THAN 1/3 THE DIAMETER OF THE WHEEL OR UNEQUAL SIZES.
  • NEVER EXCEED MAXIMUM FREE OPERATING SPEED indicated on the wheels, labels or printed in pertinent literature. These speeds are based on the strength of the wheels and there is no intention to imply that these are the best or most efficient operating speeds.
  • Allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before applying work.
  • Never jam work into wheel or grind on side of wheel.
  • Immediately stop equipment if unusual vibrations or changes occur. Unusual vibrations can cause machine damage, marred work surface and cause stresses, which could contribute to wheel failure.
  • Never Use non-woven abrasive to polish / deburr hot surface.
  • Finishing is a slow and step-by-step procedure. Always select suitable wheels from a rougher grade, then gradually progress to a finer grade of the product.
  • Do not expose non-woven products to concentrated Acids/Alkalis /Organic solvents.
