Loosen both nuts on the spring housing, approximately 1/4
counter-clockwise rotation. Under no circumstances must

Rotate the spring housing about its own axis until the pin

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 not
touch the return spring housing.
