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
Dangers
- generation of hot sparks that are expelled in varying directions
- sparks fly very far and deposit themselves as fine dust
- the workpiece heats up and stays hot for a while
- the Kingcraft grinder has no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
- the disc can get stuck if it is shifted while deep in a cut
- metal dust can be a health hazard when inhaled
Precautions
- wear goggles AND a face shield to protect your eyes
- wear ear defenders
- wear a proper breathing mask when working with a grinder
- coordinate your activity with others in the area
- understand the spark direction, which will always be tangential to the point of the disc that is in contact with the workpiece
- wear suitable gloves to prevent burns from sparks or the workpiece
- put the workpiece in a vise or clamp it down during grinding
- if the power has been lost for whatever reason, always return the power button to the "off" position before restoring it!
- be prepared for kickback
- do not attempt to vacuum up sparks! The dust collection bag could catch fire
Suggested Reading
Besides these safety notes, you should know about abrasive discs, especially the difference between grinding and cutting discs!
