The wind lock catches comprise of a set of auto-engaging hooks at one end
of the platform and a single gravity type catch at the other. The purpose of
these devices is to prevent up-lift of the platforms in windy conditions. To
engage the auto wind lock (AWL) simply tilt the platform at the angle shown
before placing the hooks onto the rung of the end frame. Lower the
opposite end of the platform onto the opposite end frame rung and the
gravity type lock will automatically engage. Simply lift and hold the gravity
lock before tilting the platform to dis-engage the opposite AWL hooks when
removing the platform on tower disassembly.

INSPECTION, CARE & MAINTENANCE
Keep all components clean and free from contaminants. If any part becomes contaminated with paint, acid, oils or similar
products the tower must not be used until the effected components have been cleaned and re-inspected.
All components should be stored in a dry location where they will be protected from adverse weather conditions. When
storing or transporting, keep frames upright and platforms flat. do not stack excessively to avoid stress damage.
Please contact Pop Up Products for further details on maintenance and repair of your MI TOWER STAIRS components.
The walk-through gate frame includes a gate/ladder which is
used to access the upper levels of the Mi TOWER STAIRS and
once unlocked and opened, allows access into and through the
base of the MI TOWER STAIRS. To open the gate/ladder remove
the clip and lift the gate/ladder upwards. It can now be swung
inwards or outwards to allow access.
The vertical tubes also feature positioning rings that will be
used when building the Mi TOWER STAIRS and allow the
guardrail brace panel hooks to be correctly positioned.
A set of conjoined frames can be created by disengaging the
frame clips on one four rung frame and fitting it to a second
four rung frame. Engage and apply the Easy-Clip frame clips to

BEFORE YOU START
PREPARATION
The floor area must be clear of any obstructions including materials and debris. Check that you have all the
components necessary to construct the tower height you require. Check also each component for condition and
correct function. If any part is missing or damaged/not working correctly it must be replaced before assembling
3T (THROUGH THE TRAPDOOR) SYSTEM
The 3T method of construction has been developed to reduce the risk of an erector falling from a tower during
construction. The erector must sit on the platform with legs through the hatch and feet on the frame rungs when
attaching guardrail brace panels above the platform. This ensures the erector is always protected by a set of
guardrail brace panels.
ASSEMBLY GUIDE
These instructions must always be made available to the user. If replacement copies are required, please contact
your supplier. This assembly guide is to be made available on the location of use of this MI TOWER+.
DAMAGED COMPONENTS
Regularly inspect all components for damage. Damaged components must be quarantined so that they cannot
be used. Where safe to do so, the component can be repaired but only by a qualified repairer. If in doubt contact
your supplier for advice.
MOVING YOUR Mi TOWER STAIRS
If Mi TOWER STAIRS is to be moved to a new location or a new level, it must be fully dismantled and rebuilt at the
new location.
DISMANTLING YOUR MI TOWER+
MI TOWER STAIRS is easily dismantled by simply reversing the erection procedure. Make sure that the
component hangers are evenly loaded to ensure your MI TOWER STAIRS remains balanced. You must, however,
be protected by guardrail brace panels when standing on any platform and ensure that you use the 3T method
when removing guardrail brace panels.
AFTER ASSEMBLY
After assembly the following information needs to be displayed on the access tower and should be clearly visible
from the ground. (e.g. on a tag).
The name & contact details of the responsible person

GETTING STARTED
GETTING STARTED
MI TOWER STAIRS requires two persons to assemble and dismantle it.
STABILISERS POSITIONING
Stabilisers are supplied and must be used for all MI TOWER STAIRS heights.
where the heights of the wall is a minimum of two thirds the height of the top working platform.
Ensure that all four stabilisers’ feet are in contact with the ground and that the ground can support the weight
of the tower and stabilisers.
TYING IN
Mi TOWER STAIRS heights outside the scope of this instruction guide or instances where the standard stabilis-
ers cannot be deployed as instructed, such as in narrow stairwells or outdoors, can be built using special
components and tying in the Mi TOWER STAIRS structure to add stability. In these instances contact the
manufacturer for further information and guidance.
When used, select and install anchors in concrete and masonry must be selected and installed in
accordance with BS 8539.This prefabricated tower scaffold has been designed to be properly secured to
a suitable adjacent supporting structure capable of withstanding the forces that will be imposed upon it
by the attachment of the tower. Devices for securing the tower must be simultaneously rigid in both
tension and compression and capable of withstanding and transmitting the loads imposed by the tower too
the supporting structure.
BALLAST
Where shown in the component list, ballast must be used to stabilise against overturning. Only use solid
materials as ballast (i.e. no loose materials) and position to avoid overloading individual components. Ballast
should be supported by the base of your Mi TOWER STAIRS and securely fastened to prevent removal.
