3.2 Prosthesis knock out: Adjust the opening of the jaws to the prosthesis outside dimension to be extracted ( by the spreading jaws adjust it to the inside dimension ). The adjustable clamping jaws can clamp objects of 5-110 mm ( at the spreading jaws of 18 – 80 mm ). Turn the lever, which is in a vertical position for Extractor, to clamp firmly the prosthesis, then press the lever to the handle.

ATTENTION: use the bolt always with the plasticinset together! 4.3 Preparation Brand new instruments and those returned from repair must be removed from their transportation packaging before storing and / or inclusion in the instrument usage and processing cycle. 4.4 Storage Store it at room temperature in dry rooms. Condensate may cause subsequent corrosion damage. Never store it near chemicals such as active chlorine which emit corrosive vapors. To avoid mechanical damage during processing, store it from the beginning in suitable racks or retainers. Before using, they must be sent through the entire processing cycle in the same manner as used instruments. The reprocessing comprises: – Preparation ( pretreatment, collecting, precleaning and taking the instrument apart. – – – – – – Cleaning, disinfecting, rinsing, drying Visual inspection of clearness and acceptable condition of material Care and repair where required Functional test Marking Packaging and sterilization, approval for reuse and storage Validated cleaning, disinfecting and sterilization processes, supplemented by defined configurations for loading the washers/disinfectors and sterilizers are an indispensable prerequisite for quality assurance. Automated reprocessing with thermal disinfection and steam sterilization should be preferred. Use correct water quality! When using softened water, especially when applying thermal disinfection in the final rinse, anodized aluminium surfaces might be subject to attack due to an increased pH value. Using demineralised water for steam sterilissation, limit values for feed water quality conforming to EN 285 and ISO 17665 are required. No spoting We recommend using demineralized water for the final rinse for the following reasons: – – – – No increase in concentration of corrosive constituents, e.g. chlorides No dried crystalline residues which could have a negative effect on the downstream sterilization process Protection and stabilization of anodized aluminium surfaces 4.5 Returned instruments Only if the instruments have been cleaned, disinfected, dried and have been declarated
