Assembling the hose fittings
Oil the thread of the union nut, the cutting ring and the screw neck. Tighten the union nut with the
wrench until the point where the union nut can only be turned with considerably more force. Turn the
union nut of the screw fitting approx. 30° to 60° further but not more than 90°. For this the screw neck
must be held with a wrench. Remove excess oil from the screw fitting
