This is the content required for an introduction to our disc grinders - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Let's begin! First off, make sure you have read the machine's manual, if available (should be linked from its InfoBox).
Safety
Breathing protection might also help depending on your material, but unless it can filter fumes you should always take care of sufficient ventilation. [1]
| Dangers | Precautions |
|---|---|
| generation of hot sparks that are expelled in varying directions |
|
sparks fly very far and deposit themselves as fine dust
|
take care of sufficient ventilation and/or wear a fume-filtering respirator when working with a grinder |
 |
if the power has been lost for whatever reason, always return the power button to the "off" position before restoring it! |
 |
wear suitable gloves to prevent burns from sparks or the workpiece |
| possible kickback if the disc gets caught on the material | |
| aluminum can clog an abrasive disc and cause it to overheat until it breaks | do NOT use abrasive discs on aluminum |
| a disc that is off-center or loose is very dangerous | after inserting a new disc, let it run freely for a minute and make sure it runs safe and true |
Suggested Reading
Besides these safety notes, you should know about abrasive discs, especially the difference between grinding and cutting discs!
