Installing hose unions
Oil the thread of the union nut, the cutting ring and the thread of the connecting piece. Tighten the
union nut with a spanner until the union nut becomes more difficult to turn. Turn the union nut further
by approx. 30° to 60° but only to a maximum of 90° while holding the connecting piece with a spanner.
Remove excess oil from the union.
