ANGLE GRINDER 101 Changing Wheels and Safely Using the Angle Grinder
The angle grinder can be the most underestimated tool in the shop and everyone should be conscious of what it is capable of. Safety is the most important introduction we can give when talking about how to operate the angle grinder.
- Please make sure the machine is unplugged and press in the lock button on top of the grinder nearest to the wheel head (bearing kit). While holding the lock button, use the spanner wrench to loosen the flange nut in order to remove the wheel you wish to change out. Also, make sure that there is a spacer flange under the wheel, which helps raise the wheel away from the hood/guard.
- Now it is time to install your new wheel! Fit the metal ring of the wheel around the raised area of the spacer flange and begin threading your flange nut onto the spindle. While holding the lock button, tighten the flange nut onto the spindle using the spanner wrench.
- Once your wheel is installed safely, you can plug the angle grinder back into power. Idea Foundry’s Milwaukee 4.5” angle grinder has a safety button, which is the smaller button above the paddle button that starts the operation of the tool. You must press in the safety button before the paddle will engage to start the machine.
- While grinding, make sure to focus on using the outside of the wheel because hitting the flange nut or spindle can burn out the motor and cause it to cease from working.
- Lastly, DO NOT wear gloves or loose clothing while using the angle grinder because it has a spinning wheel that can catch/eat those items. Make sure to wear ear muffs and a face shield to protect yourself from the tool’s loud noise as well as sparks and pieces of flying metal.
