Additional information


  • Make sure all cables are clear of the router.
  • Make sure the work piece is correctly supported.
  • Always use protective goggles when using the router.
  • Do not switch router on with blade touching the work.
  • Never remove the router when it is switched on and moving.
  • Make sure there are no obstructions to the path of the router.


  • Never try to cut more than 10mm depth on one cut.
  • Do not force the router too fast. This can damage expensive router bits.
