The gap between the step and the stair stringer forks
should always be approx. 1.5mm so that the axis
can be inserted in the next step.
If you have pushed the step too deeply into the stair
stringer element, pull the step out again a little until
the gap is approx. 1.5mm.
8.1.18.
Connect the inserted steps with the stair stringer:
With the axis srew supplied, one axis screw is
shorter
than the others.
Use the
short
axis screw. Unscrew the attached
nut and insert the short axis screw into the drill hole
of the stair stringer element.
On the opposite side, screw the nut onto the axis
screw and tighten the nut using a spanner (wrench
size 10) while fixing the head of the axis screw with
an allen key.
Adjust the nut so that the step can be moved with
slight to moderate resistance. The step should
not remain rigid in any position, but should not fall
down easily. If the step is difficult to move up and
down, loosen the screw connection slightly.
If no resistance is felt when lifting the step, tighten
the nut further. A slight damping of the step is opti-
mal (tightening torque 2Nm).
