appropriately sized spanners (in the hexagonal body of the joint and the unit
nut) unl the two sides are connected to the boom or unl you feel denite
resistance.
5. Use a marker or a pen to mark the line in the direcon of the length from the joint
nut to the division, adding another 1/6 or 1/4 of a turn. Line misalignment will
act to indicate the degree of ghtening. The nal turn has the purpose of ensuring
