TECHNICAL DATA SHEET First, make sure that the piling up of the spring washers is according to the range of adjustment desired. > ? Adjust the apparatus with a dynamometric key ? Tighten the nut with a HN 4 slotted key > ? Insert the braking washer with spurs on the periphery ? Handtighten the adjustment nut until it touches the spring washers. Locate theslot on the nut which coincides with one of the engravings of the box. This is the reference of the adjustment. ? Read in the table (see the verso) the number of divisions permitting to obtain thedesired torque. ? With the right spured spanned (see the following table), tighten the nut by thecorresponding value, then press down the spur facing the slot of the nut to ensure the braking.Size012345 Spure spannedHN 7HN 8HN 11HN 13HN 16HN 18 ? For the size 0 apparatus, use a dynamometric key to have more precision in the setting off torque. > ?
