This is the content required for an introduction to our rotary tool - 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.

Safety

Dangers

rapidly spinning exposed chuck & bit, binding can cause kickback
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
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 disc and cause it to overheat until it breaks

Precautions

make sure the collet is properly tightened around the inserted bit
stay clear of the rotating accessory and the direction where kickback might occur
wear goggles to protect your eyes
wear ear defenders if its too loud (normally you don't need them)
put small workpieces in a vise or clamp them down
if the power has been lost for whatever reason, always return the power button to the "off" position before restoring it!
let the tool reach full speed before contacting the workpiece

and, depending on the bit and material:

wear a proper dust mask when generating dust or sparks
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 use abrasive discs on aluminum
do not apply any side force to cut-off wheels, they could shatter!
- in general only little force should be applied while cutting. Let the tool do the work.

Demonstration

The tutor will show you these steps in detail:

inserting a bit
attaching a handling accessory, e.g. the flexible shaft
