The screw head must „stick out“ 3-4mm from the
surface so that the tap fitting can later accommo
-
date the screw.
8.2.11.
Position the tap fitting again at the lowest mark
or,
in the case of thin ceilings,
at the marked
position (8.2.6 ff).
The exact positioning is crucial! (8.2.8)
Mount the tapping fitting on the outer
stringer, pre-drill holes with a small drill
(e.g. 3mm) and then screw the tap fitting
to the front of the stringer with the Spax
screws (5x25).
The countersinks of the drill holes in the
tap fitting must face outwards.
8.2.12.
Adjusting the screw of the tap fitting:
Unfold the staircase and check that the screw of
the tap fitting is positioned almost without leeway in
the leg of the tap fitting.
This is the case if
no gap
is visible between the
fitting and the ceiling when the staircase is comple
-
tely unfolded.
The leeway can be adjusted by screwing the screw
of the tap fitting in or out.
The outer stringer (tap fitting)
must not tap
too tightly
into the screw of the tap
fitting.
To protect the front side of your ceiling
from abrasion, we recommend that you
attach a protection in the form of felt,
cork, foil or similar underneath the tap
fitting screw.
