INTRODUCTION: This chapter explains how to use the machine. First of all, make sure that the person operating the machine is duly protected and that all safety measures are being followed.

  • Page 63: Filling The Tank

    Filling the Tank: Before filling the tank, put on goggles, gloves and a long-sleeve shirt to prevent possible burns caused by hot adhesive splashing. Make sure that the tank is clean and free of foreign particles. Fill the heated tank with the hot–melt material up to a maximum of 10 mm below the edge of the tank.
  • Page 64 Filling the Tank (Only Isomelt Mini Plus): 1. The adhesive is received from the supplier (Figure A). 2. Take the bag out and cut the bottom part with a cutter (Figure B). For big consumptions, cut a circle of 10 cm diameter and centred in the bottom part.
  • Page 65 3. Insert the PUR product (Figure D). The block should look as indicated in figure E. Do not remove any more of the packaging. Close the cover and turn the cylinder selector to the down position ↓ (Figure F). When the equipment activates the pump, the cylinder begins to press the adhesive block.

    6.3.2. MOTOR REPLACEMENT: Follow these steps to replace the motor: 1. Make sure the machine is off. 2. In the bottom of the device, release the stud holding the coupling to the motor shaft. 3. Loosen the four hex nuts that secure the motor to the support, to remove the motor backwards.
  • Page 73 6.3.3. BLEEDING: The bleed process is done to sweep away small crystallisations that may be produced in the filter and if you wish to depressurise the system. Before purging the filter, put on goggles, gloves and a long- sleeve shirt to prevent possible burns caused by hot adhesive splashing.

  • Page 74: Replacing The Adhesive Filter

    6.3.4. REPLACING THE ADHESIVE FILTER: Before changing the filter, put on a face shield, gloves and a long-sleeve shirt to prevent possible burns caused by hot adhesive splashing. Keeping a filter or mesh in stock to replace when necessary is recommended. This replacement is quick and improves the machine performance.
  • Page 75 6. Insert the replaced part into the hole and close the cover. 7. Re-connect the electricity from the gun to the hose. 6.3.6. CLEANING THE GRID / MELTER (ONLY FOR ISOMELT MINI PLUS): Before cleaning the grid and the melter, put on a face shield, gloves and a long-sleeve shirt to prevent possible burns caused by hot adhesive splashing.
