When first used a sintered wire must be
twisted about 1 - 1.5 times per metre length in
an anticlockwise direction.
To ensure uniform wear on the wire beads,
change the twists of the wire often by about +
or - 30%, but never under 1 x per metre of
wire. Changing of the twists should take place
after every cut.
