  • Page 3: Introduction

    1. Introduction Dear Customer, thank you for purchasing this product. This product complies with the statutory national and European requirements. To maintain this status and to ensure safe operation, you as the user must observe these operating instructions! These operating instructions are part of this product. They contain important notes on commissioning and handling. Also consider this if you pass on the product to any third party.

  • Page 4: Intended Use

    The products described in these instructions are intended for installation in or attachment to the RF500 Maker construction kit and partially to the RF500 finished device. If the retrofitting set for the heatable printing bed and the metal housing is installed, the RF500 Maker construction kit is identically equipped as the RF500 finished unit.

    5. Safety information Read the operating instructions attentively and particularly observe the safety notes. If the safety notes and the information in these operating instructions regarding proper handling are not observed, we assume no liability for any resulting injury/ property damage. In such cases, the warranty/guarantee will also lapse. a) General information • For safety reasons, any unauthorized conversions and/or modifications to the product deviating from these operating instructions are not permitted. Components may be damaged and thus impair the function or safety of the device. •...

  • Page 7: C) Set-Up, Site Of Operation

    c) Set-up, site of operation • Set up the 3D printer only on a stable, horizontal, sufficiently sized surface. • Choose the site of operation so that children cannot reach the product. • When setting up the 3D printer, observe that the mains plug of the mains unit must be easy to reach so that the device can be disconnected from the mains voltage quickly and easily in case of malfunction.

  • Page 10: General Notes And Information For Assembly

    7. General notes and information for assembly a) General information Take enough time for the assembly. Hurrying often leads to mistakes that may damage components or ruin the time benefit by elaborate rework. The workplace should be sufficiently large and clean so that the different components and assemblies can be put down and installed easily. Always observe the images during assembly. Here, the assembly locations and correct alignment of the components are shown. All mechanical components of the construction kit are produced extremely precisely. Never apply any force during assem- bly. All parts can be assembled without any great application of force. If this is not the case, rethink the assembly step and reread the corresponding description in these instructions. When tightening the screws, ensure that you do not tighten them too tightly. Many screws are turned into aluminium threads and therefore must not be tightened as far as it would be possible, e.g., in steel threads.
