Adjustment of the touch-down point

The actual touch-down point (ﬂoor 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.

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 qualiﬁed

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
