Production Information and Assembly Guide
Refer to the table below for the correct method(s) of stabilising the tower for the stairwell in which you intend to erect it:

0.8 to 1.4m
1.4 to 2.0m
2.0m or greater

For additional stability more than one stabilisation method may be used.
The manufacturer strongly recommends
that ballast be used
in all applications in addition to the alternative methods indicated by this guide.
Methods of stabilisation
A.
Strongly recommended:
The tower is fitted with 150kg of
ballast uniformly spread along the bottom rung of each base
frame (i.e. 75kg at each end). Please contact your supplier or
hire shop for details.
B.
The tower is positioned up against a wall on one side, and a
stabiliser is fitted on the other, to the end frame on the lower
step. The stabiliser must have a minimum sideways extension
of 650mm, and reach down the stairs for a minimum distance
of 650mm.
C.
The tower is fitted with a stabiliser on both sides, each with
a minimum sideways extension of 650mm, and reaching
down the stairs for a minimum distance of 650mm. Additional
stabiliser available from your supplier or hire shop.
D.
The tower is fixed solidly to a wall on one side with ties. They
should be rigid, two-way ties fastened to both uprights of the
frame with load bearing right-angled or swivel couplers. Only
couplers suitable for the 50.8mm diameter tube of the tower
should be used. Ideally ties should secure to either the face of
a solid structure or by means of anchorages. Tying in with rope
or non-rigid members is not acceptable.
Equipment Care
Never use the tower for anything other than its
intended purpose as a work platform.
Keep the tower clean, paying special attention to the
deck You will find this easier if you clean up regularly.
When not in use, store everything somewhere clean,
dry and safe.
Finishing Off
To dismantle the tower, start at the top and work down,
reversing the erection procedure.
Work through the steps in strict sequence.
Components can be damaged by the use of excessive
force. Do not use hammers, etc. to force joints apart.
Always lower components to the ground carefully
when dismantling the tower. Never simply drop them
as damage or serious personal injury may occur.
