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.

Suggested Reading

When you use this tool, please read & add to the information about rotary tool bits!

Demonstration

The tutor will show you these steps in detail:

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