This page is INCOMPLETE and still missing some important information before it can be used as a resource. Please use the "Discussion" feature above or talk to one of the tutors if you would like to help improve it. Thanks!

This is the content required for an introduction to our bench grinder - 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 can fly far and deposit themselves as fine dust
the workpiece heats up and stays hot for a while
has no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
metal dust can be a health hazard when inhaled
aluminum can clog an abrasive wheel and cause it to overheat until it breaks
the workpiece can get caught on the wheel and get jerked from your hand

Precautions

wear goggles to protect your eyes
wear a proper dust mask when working with the bench grinder
wear suitable gloves to prevent burns from sparks or the workpiece
do not attempt to vacuum up sparks! The dust collection bag could catch fire
do not attempt to grind aluminum
let the wheels get to full speed before you start grinding
use the tool rests whenever possible
make use of the grinder's plastic spark guards, if available
