  • Page 5: Safety Instructions

    The GP20 Hybrid is a powerful and effective plastic processing machine, processing your plastic waste plastic to granulate. The processing process inside the GP20 Hybrid consist of a multitude of moving components, moving at high speeds and/or great force. Which if improperly used can cause serious harm.
  • Page 6 Never modify or manipulate any of the safety switches or other components of the machine, this can cause extremely dangerous situations. ⚠ WARNING Only use the GP20 Hybrid with the 3devo hopper mounted on the machine. ⚠ WARNING Never change or remove guards when the machine is powered.
  • Page 7 ⚠ CAUTION The machine is designed to process plastics only. Any non-plastic materials that are inserted in the machine can cause the machine blades to wear out fast. Non-plastic materials can also damage the machine itself. Always make sure the plastic parts do not contain any non-plastic pieces or particles.

  • Page 66 Step 7) Repeat step 1 until 4 until all blades are placed. Step 8) The hexagon shaped part of the shaft should be completely covered with shredder blades and spacers. In the illustration below, the blade and spacer have an 1,3mm overlap. The overlap may vary as long as there is some overlap.
  • Page 67 Step 9) Slide the front plate back on the shafts. Make sure the front plate is cleaned properly around the cylindrical bushings. Step 10) Start by placing one thin nut per shaft and tighten the nuts a little bit at a time. Even tightening is important to avoid imbalances in the stacked blades.
  • Page 68 Step 12) Screw in the four bolts in the corners of the front plate using a 8mm Allen key. Step 13) Mount the black casing plate back on the machine by screwing in the two bolts also using a 8mm Allen key.
