grinding with a bonded wheel on an angle grinder

Video Transcription

Read carefully the instructions in the machine handbook and the safety leaflet supplied with the wheel.

Use the correct size and type of guard recommended for grinding


Check the marking:

  • Declaration of conformity to the Standard EN 12413,
  • The speed in RPM marked on the wheel is equal or greater than the speed marked on the machine,
  • Expiry date, often stamped on the metal centre

Follow any instruction on material suitability given by the manufacturer.

Do not use a damaged wheel.

To be safe, make sure the machine is isolated.

Fit the guard for grinding and check that it is correctly adjusted to protect you from debris, especially in case of breakage. Never use a machine without a guard.

Fit the handle.

Locate the back flange on the keyway, then the wheel on the back flange, without force or excessive play.

Then fit the front flange and make sure it clamps the wheel.

Tighten with the pin spanner without excessive force.


Wear your personal protective equipment:

  • Suitable clothing
  • Mask,
  • Eye Protection,
  • Ear protection,
  • Protective gloves


Make sure that the work piece cannot move and working area is clean and tidy, and no other person is at risk.

Reconnect the machine, start it and let it run freely at least 30 seconds to ensure that the wheel does not break or run with excessive vibration.

Work in a stable position. Always hold an angle grinder with both hands.

Grind at an angle of about 30 degrees to the workpiece moving from side to side, without excessive force on the wheel to not damage it.

After turning off the machine, wait until the wheel has stopped running before putting down the machine and unplug it.

Never force the wheel to stop.

Remove the wheel if it is not to be used again.

Never grind flat to not wear the outside of the reinforcing cloth.

Never use it on edge.

Follow all the safety recommendations to avoid serious injury.

In case of injury, call the emergency services.
