For reversal, it must first be pulled from the cone in axial direction. A pressure spring holds the handle in both positions. When swung out, it automatically engages again. The cover conceals clamping elements, e.g. countershaft pulleys, as well as protruding and recessed shafts. For mounting, the cover is pushed in by hand. For dismantling, the cover can be raised and taken off by applying moderate pressure in the rim of the cover. see also... • Countersunk Washers GN 184 (for Axial Fixing) → Page 1090 • Handwheels with Retractable Handle GN 524.3 (Plastic) → Page 263 • Handwheels with Retractable Handle GN 520.4 (Plastic, Duroplast, Retractim mechanism Steel) → Page 259 Information • Plastic Technopolymer (Polypropylen PP) - - Reinforced, shock-resistant - - Temperature resistant up to 80 °C - - Black, matte finish • Hub bushing Steel, blackened • Cover - - Plastic, black for d 1 = 80 - - Plastic, light gray for d 1 ≥ 100 • Retractable handle - Plastic, Technopolymer (Polyamide PA)    Black, matte finish - Retracting mechanism    Steel, blackened • Keyway P9 DIN 6885 Page 1 → Page 2078 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification • With safety retractable handle (swivelling) • Cover in other colors On request 1 3 d 1 d 2 H7 Bore d 3 d 4 d 5 d 6 d 7 b h l 1 l 2 l 3 r Ø Handle  80 8 10 18 16   25 13,5 16,5 20 4 17 38 45 28 15,5 100 10 12 22 20   30 25   27   24 9 22 34 45    39 15,5 125 12 14 26 24   35 28   31   28 11 27 39,5 60 49 18   150 14 16 26 24   38 30   34   32 10 30 44 65   58 22   175 16 20 35 33   44 35   39   36 16 28 49 80    70 24   200 20 24 40 38   50 40   44   39 13 36 53 90    81 25   250 20 - 40 38   57 48   50   43 19 36 60 90   104 25   300 20 - 40 36,5 72 65   68,5 46 18 44 66 90   124 25   Original design VDS+IR
