1.3 Maintenance - Storage – Transport
•The MiniMax mobile tower system is robust and requires little maintenance.
•All components and their parts should be regularly inspected to identify
damage, particularly to joints.
•Refer to the MiniMax Inspection Guidance for detailed inspection and
maintenance advice, the guidance is available to download at:
www.minimaxtower.com.
•Threads, hinges, and brace latches may be lubricated with light oil. Ensure oil
does not contaminate climbing or walking surfaces.
•Safety labels should be kept legible. Replacement labels are available from
Werner UK Sales & Distribution Ltd.
•Surfaces should be kept reasonably free of dried paint, plaster etc.
•Use of solvents on wooden platform surfaces and plastic components should
be avoided.
•Components should be stored in clean, dry conditions with due care to prevent
damage.
•During transportation ensure components are not damaged by excessive
strapping forces.

2 Building The Tower
2.1 Pre-Assembly Checks
•Check overhead that the area into which the structure is to be erected contains
no obstructions, particularly electrical or radio radiation hazards. The structure is
conductive.
•Ensure the ground on which the mobile access tower is to be erected is capable
of supporting the tower in use.
•Check the surface is level to 0.6°. If not the optional adjustable leg kit must be
used. This allows adjustment up to 210mm.
•Only components specified in this manual shall be used with MiniMax towers.
Check all required components are onsite and in a suitable working condition.
•Damaged components shall not be used and must
be put beyond use and disposed of according to local
regulations.
•Adjustable legs should only be used for levelling purposes and never to gain
extra height.
•Ensure distance from the ground to first climbing rung is less than 400mm.
•Only climb the tower from the inside using the access
method provided.
•This tower provides a work platform. It must not be
used to access other structures.
•Tower scaffolds are not designed to be lifted or suspended.
•Ensure the safe working load on the structure is not exceeded.
5mm
PN00063300_Minimax_IM_RevD 0522.indd 4PN00063300_Minimax_IM_RevD 0522.indd 4 01/06/2022 10:5401/06/2022 10:54

•Tools and materials should be lifted using a reliable lifting material (e.g. a strong
rope) employing a reliable knot (e.g. clove hitch) to ensure safe fastening and
always lift within the footprint of the prefabricated tower scaffold (i.e. within the
area bounded by the stabilisers).
•Check this manual is available and its contents familiar to all those involved.
•If assembling outdoors; check the forecast windspeed.
º The assembled tower is certified to wind forces
equating to 27mph, but handling components under
those conditions would be hazardous.
º Also consider the wind funnelling effect of nearby
buildings.
•This structure is designed to be self-supporting under the loading condition
requirements of EN 1004-1:2020 and does not require tying in. Consideration
should be given to potential wind conditions if the tower is left unattended.

SP4 and SP10 stabilisers must always be fully extended.
Position the lower clamp so that the arm is as close to horizontal as possible. Adjust
the position of the top clamp to ensure the stabiliser foot is in firm contact with the
ground. Ensure the clamps are secure.
2.5 Adjustable Legs
If the ground is uneven or sloping you will need to fit
adjustable legs. Turn the base unit upside down so
that the wheels are facing upwards. We recommend
that two persons are required to ease the process.
Using a 19mm spanner loosen the fixing bolt and
remove the castor from the base.
Follow the instructions in the adjustable leg pack to
change the large castor spigot to the smaller one supplied in the
pack. Insert the castor into an adjustable leg and then retighten
the fixing bolt with the spanner, following the instructions. Repeat
this process for the other castors and adjustable legs. Insert the
four leg and castor assemblies into the base unit.
Turn the base the correct way up with the wheels on the ground.
Use a spirit level to check the base unit is level.
Adjust the legs as necessary, to level the base unit.
Important - Only use the adjustable legs to level the base
and not to gain extra height.

2.6 Assembly
This tower structure must be assembled, and components oriented, in accordance
with this instruction manual. Deviation from this instruction manual is not permitted.
THIS TOWER MUST NOT BE USED AS AN ANCHOR POINT
FOR PERSONAL FALL PROTECTION EQUIPMENT.
•To fit the optional adjustable legs, a 19mm spanner is required. No other tools
are needed for assembly.
•The assembly uses the 3T (Through the Trapdoor) method that provides
collective fall protection.
º From the sitting position in the trapdoor opening fit all guardrails before
standing on the platform.
º Fit braces in the locations described and
ensure the claws are locked.
•The tower may be assembled by a single person, but it is recommended that
two or more are used to pass up components on the taller assemblies.
•Components must be lifted within the footprint of the tower using a reliable
method such as a strong rope with a clove hitch knot.
•Castor brakes should be locked as soon as the tower base is in position.
•The tower base should be levelled to within 0.6° before continuing the assembly.
•The adjustable legs are for levelling the tower only and not to be used to gain
extra height.
•Ensure when the base is levelled the distance from the ground to the first
climbing rung is less than 400mm.
•Stabilisers of the size specified in the quantity schedule should be fitted at the
earliest opportunity.
