Adjustment of the touch-down point
installing the stairway.
The actual touch-down point (
floo
r contact) of the stairway can be adjusted to suit individual
stairways as follows:
Extend the stairway out to the desired touch-down point (15° is the minimum angle). Slacken the
lock nut (item 4) and turn the adjustment bolt (item 3) un l it stops. Tighten the lock nut; the
stairway will be set to extend to this touch-down point.
Once any adjustment has been carried out we would recommend that you check that the treads are
horizontal to the
floor
.
The angle of the treads can be adjusted by slackening the two nuts on the underside of each tread.
Reset all treads on the stairway so that they are horizontal.
the drop rate/speed
installing the Stairway
Loosen the lock nuts (6), adjust the spring tension by turning the adjustment screw (5). Ensure that
care is taken that components do not twist out of posi on. The components must be aligned and
parallel to the opera
arm (2). Hold the spring in posi
(to prevent further rota
and
misalignment) and ghten the lock nut.
Both springs must be adjusted equally.
the Spring Tension of the Stairway
The stairway is supplied with the correct spring tension, which is set at the factory. If the spring
tension needs to be adjusted we recommend that this is only carried out by a suitably quali
fi
ed
Maintenance Engineer.
Please Note: Spring adjustment must be carried out with the stairway in the closed
on.
It is important that a Ø10mm x 300mm long steel bar (‘Tommy Bar’) is used in the loca ng holes of
the die-cast spring roller (item 8).
To increase the tension, place the steel bar in the hole next to the domed headed stud (item 9) and
rotate un the stud can be removed.
Rotate the spring roller un l it is possible to place the stud into the next hole adjacent to where the
stud was removed. Once it is safely in posi on allow the roller to rotate slowly back so that the stud
is back against the bracket and remove the steel bar.
Both springs must be adjusted equally.
Please Note: The Springs (item 7) are under high tension so extreme
and care must be taken when carrying out any adjustment.
It is important that the correct size Steel Bar is used, if any doubt
please contact us and ask to speak to a Technical Advisor.
