During mounting, easy blows with a soft hammer are sufficient to drive the knob into place, the shaft end should be slightly rounded or chamfered (30°). The knobs sit absolute vibration-tight. The transparent sight glass allows symbols to be placed underneath. Once the knob is mounted on the shaft, the symbol is placed into the recess of the separately supplied sight glass and driven home with a soft hammer. The symbol is fully protected from dirt and liquid by the tight connection between the sight glass and the knob. Positioning and control symbols are to be ordered separately. see also... • Softline-Mushroom Shaped Handles GN 718.1 (Press-On Type) → Page 78 Information GN 518 Tapered Knobs for Positioning Symbols 1 d 1 2 d 2 How to order 1 2 GN518-32-B10 • Plastic Technopolymer (Polyamide PA) - - Temperature resistant up to 90 °C - - Black, shiny finish • Transparent sight glass with magnifying effect • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification Original design IH.N • Positioning and Control Symbols GN 517.1 → Page 65 Accessory
