The guard ordesign shall function through the full range of inclinationpossible and through the full range of belt tension adjustment.The guard configu
22、rations shown in Fig. 2 are suggestions thatmay reduce the risks associated with this area. Fig. 2 assumesthat the treadmill is maintained and adjusted per manufactur-ers recommendations.4.2.1.1 The intention of Fig. 2 is to show some possiblealternatives that have been used previously on treadmills
23、 toguard the rear roller area. This figure is not intended to limitalternatives that may more effectively address the hazard that ispresent at the rear roller. The function of the guard is tominimize the possibility of finger entrapment between theroller and the moving surface and between the frame
