INFORMATION
If the tension has increased, rotate the housing
clockwise and if the tension has decreased rotate
the housing counter-clockwise. Ensure that the
notch is always snapped into the spring housing
properly and subsequently tighten the nut. The
second nut secures the first nut (capped nut).
When the nuts have been tightened they should
