  18. REPAIR INSTRUCTION 
    1. Clean the front bumper cover surface.
      1. using a heat light, heat the front bumper cover surface.
        NOTE:
        • Do not touch the heat light and heated parts.
        • Touching the heat light may result in burns.
        • Touching heated parts for a long time may result in burns.
      2. wipe off any tape adhesive with cleaner.
    2. Installation temperature.
      1. When the ambient temperature is below 15°C (59°F), perform the installation procedure after warming the front bumper cover surface (installation surface of the front bumper cover) and tape to between 20 and 30°C (68 and 86°F) using a heat light.

        When the ambient temperature is higher than 35°C (95°F), cool the front bumper cover surface (installation surface of the front bumper cover) and tape to between 20 and 30°C (68 and 86°F) prior to installation.

        HINT: 

        • The most appropriate temperature for installing the tape is 25°C (77°F).
        • When the temperature is low, the tape turns stiff and falls off easily. When the temperature is high, the tape loses elasticity.
    3. Before installation.
      1. Make sure any dirt on and around the front bumper cover surface where the tape will be installed (installation surface of the front bumper cover) is removed, and that the surface is smooth. If the surface is rough or dirt remains when pressing the tape onto the surface, air will be trapped under the tape and result in a poor appearance.

        HINT: 

        Spray water on the shop floor to settle any dust.

    4. Key points for handling the tape.
      1. The tape bends and rolls up easily. Store the tape between flat pieces of cardboard or other similar objects and keep it dry and level.
        NOTE:

        Do not bend the tape or leave it in a place with a high temperature.

    5. Key points for the installation of the tape (how to use a squeegee and the installation procedure for a flat surface).
      NOTE:
      • Position the tape with a high level of accuracy to achieve a neat finish and to avoid peeling.
      • The tape cannot be reused because it deforms and will not fit after removal.
      1. To avoid air bubbles, slightly raise the part of the tape that is going to be applied so that its adhesive surface does not touch the front bumper cover while applying the tape. Tilt the squeegee 40 to 50° (for pressing forward) or 30 to 45° (for pulling) from the front bumper cover surface and press with a force of 20 to 30 N (2 to 3 kgf. 1.45 to 6.71 lbf.) while moving the squeegee at a constant slow speed of 30 to 70 mm (1.18 to 2.76 in.) per second.

        *k 30 to 45° (for pulling) - -
        NOTE:

        Be sure to observe the specified pressing speed, force and angle of the squeegee to avoid wrinkles and air bubbles.

        HINT: 

        • Either angle of the squeegee (for pressing forward or for pulling) is acceptable.
        • Be sure to apply the tape while removing the release paper 10 to 20 mm (0.39 to 0.79 in.) from the edge of the squeegee.
    6. Key points for the installation of the tape (how to use a squeegee and the installation procedure for a hemming surface).

      *a First
      *b Second
      *c Third
      *d Squeegee
      1. If it is difficult to press the tape, press it in several steps as shown in the illustration. Use your fingers or the padded surface of a squeegee to slowly apply the tape to the hem of the vehicle, especially for a small hem.

        HINT: 

        When applying tape to the backside of a hem, remove the release paper and use your fingers or the padded surface of a squeegee.

    7. Key points for the installation of the tape (how to use a squeegee and the installation procedure for corners).
      1. Remove the release paper and apply the tape carefully with your fingers.
      2. Before applying the tape to each corner, heat the tape using a heat light and gradually apply it to avoid wrinkles in the tape and achieve a neat finish.
    8. Check after installation.
      1. After completing the application, check if the tape is applied neatly. If the tape is not applied neatly, apply new tape.
        NOTE:

        Do not reuse the tape.
