By turning the bolt

9、1lockwise, thestroke length can be increased. Conversely, turning bolt 1 clockwise will reduce the stroke length.如果行程不正确，拧松螺栓5。通过逆时针旋转圆缺螺母1可增大铁芯行程，相反地顺时针旋转螺母1则能缩短铁芯行程.vi. Adjust the bolt 4 sot the brake core moves in by about 3.0 mm (Max. allowable distanceis 3.5mm). Do the same adjustment in other
