Lightly tighten the upper clamps above the sixth rung on each corner post. Position
the lower clamp above the bottom rung. Ensure the lower arm is as horizontal as
possible. Position the stabilisers so that the footpads are approximately equidistant
from each other, as seen here. Telescopically adjust the leg and reposition the clamps
as required to make firm contact with the ground. Ensure the clips with locking pin
are in place. When in the correct position, tighten the clamps firmly.
To position the tower against a wall, do not remove the stabiliser, move parallel with
the wall.
To position the tower in a corner, remove the inside stabiliser and place the outside
two parallel with the wall.
Ballast weight maybe used to stabilise the tower, please contact your supplier for the
correct amount of ballast weight required.
STABILISERS
USAGE ADVICE
• We recommend a minimum of two people to assemble, dismantle and move the
platform tower.
• Check that all components are on site and in good working order.
• Ensure that assembly location is checked to prevent hazards during assembly,
dismantling or moving and while working on the tower. Particular attention should be
given to the ground condition, whether level or sloping, obstructions and wind
conditions. The ground condition should be capable of supporting the tower structure.
• Towers must always be climbed from the inside of the assembly and using the built-in
ladder if provided.
• Lifting operation should be done inside the effective base area of the tower.
• Moving the tower should only be done by manual effect from the base of the
tower. When moving tower be aware of overhead hazards (eg. electric cables).
• No personnel or material should be on the platform whilst the tower is being moved.
• Beware of horizontal loads which can lead to instability of the tower. The maximum
side force is 20kg.
• Not to be used on sloping surfaces.
• Do not use boxes or steps to gain additional height. If extra height required, contact
your distributor to get extra components.
• Do not lift or suspend assembled mobile tower.
• Components are normally hoisted using a rope. Always lift within the tower structure
or within the base rectangle defined by the stabilisers.
• Damaged components, or components from other tower systems should never be
used.
• Stabilisers should always be fitted when specified. Use the type of stabiliser shown
on the component list according to the tower height.
• When wind exceeds Beaufort force 4, cease using the tower. Wind speeds:

CARE AND MAINTENANCE OF TH E TOWER AND COMPONENTS
• Keep all equipment clean, especially spigots and sockets where frames join. Spigots
should fit easily into stocks. Lubricate with light oil.
• Do not strike or hammer components. Do not throw or drop onto hard surfaces.
• Lightly oil spring mechanism of the hooks.
• For transport and storage, components are best stored vertically.
• Damaged parts should be repaired or replaced, contact your supplier.
TOWER COMPONENTS REQU IRED
The following tables show a full list of components to build the tower to the platform
height specified, complying with the requirements of EN 1004 and Work at Heights
Regulations (WAHR). Total self-weight of towers are indicated.
ALTERNATIVE PLATFORM H EIGHTS
Platforms can be installed in any
rung position up to the 10
th
rung.
Use bracing frames on either side
to provide adequate fall
protection and toeboards based
on risk assessment.

To Dismantle, follow the build process but in reverse order noting the
following.
• To remove the guardrail frames or braces, first unlock the hook
at the end away from the trapdoor.
• Sitting through the trapdoor, unlock the near end hook and
remove the brace.
To Move the tower to a new position, first prepare the tower.
• Wind speed should not exceed 29 km /hr (force 4).
• Release the castor brakes.
• Raise the stabiliser feet only enough to clear obstructions.
• Ensure tower is empty (material and personnel). Move the
tower manually by applying force at the base - do not use
machinery to push or pull the tower. Once moved - prepare
the tower for use.
• Check all castors and stabilisers are in firm contact with the
ground.
• Reapply the castor brakes.
