How replace the cutting strip (1067mm 42") on the Technic ARC or Technic ARC TE

To do this you will need the Technic ARC & ARC TE Cutting Strip (1067mm 42″) >

Tools required: 

  • Cross head screwdriver 
  • Small flat ended screwdriver 
  • Pair of pliers or grips 
  • Hand and eye protection 
  • Cleaning cloth and solvent 


What to do 

The cutting head contains two very sharp circular blades, the cutting strip fixed along the edge of the base plate, although not sharp, has a very keen edge. 

  • For safety – do not place your fingers near the circular knives or the cutting strip.

  • Remove the three cross head screws holding on the base end covers in position on both ends. Be careful not to lose the cup washers under each screw between the end cover and the baseplate.   

  • Carefully slide the cutting head off the end of the baseplate. 
  • The base edge strip is held in place by a strong adhesive tape, ensure you are wearing hand and eye protection when removing/replacing the strip. 
  • Carefully lever the end of the edge strip up with a small flat ended screwdriver, grip hold of the strip firmly with a pair of pliers or grips, DO NOT grip the strip with your fingers, and pull the strip upwards to peel it back from the base. Clean the surface of any remaining adhesive or pieces of tape, using a scraper or a cloth and solvent. 
  • Check the length of the strip by laying it on the edge of the base, it should be slightly smaller than the base. It is important that when fitted, the edge of the strip does not overhang either end of the base. The strip must also be the correct way round, the edge of the strip that MUST overhang the edge of the base is indicated by a series of black ‘x’s.
    Once happy with the position of the strip, peel back the release paper from the adhesive tape and stick the strip down, working from one end ensuring the back edge of the strip butts firmly up to the edge of its recess in the base. Once in place, carefully smooth down firmly with a cloth. 
  • Replace one base end cover and position the plastic clamping strip ready to fit the cutting head. Gently slide the new cutting head onto the base, being careful not to allow the edges of the cutting wheels to touch the base. 
  • To replace the other base end cover put the three cross headed screws in the holes and then two cup washers, facing each other. Offer the end cover to the base and using  the screwdriver turn each screw in just a few turns. When all three screws have been located, tighten them, so that the cup washers are slightly compressed. 
  • The end covers can be adjusted for squareness by the tightening/loosening the three fixing screws. A square cut piece of paper can be used against the cutting edge as a gauge.
