When using these knobs a threaded shaft is not required. 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 Polyamide bushing is embedded during the manufacturing process and it does not need insertion before mounting. see also... • Domed Gear Knobs GN 719.2 (with Thread or Press-On Type) → Page 62 Information GN 719.1 Domed Gear Knobs Press-On Type 1 d 1 2 d 2 How to order 1 2 GN719.1-33-B10 • Plastic Duroplast (Phenolic PF) - - Temperature resistant up to 110 °C - - Black, shiny finish • Polyamide bushing Embeded • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification Original design I.222 N
