1.3 Maintenance - Storage – Transport
•The BoSS 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 BoSS Inspection Guidance for detailed inspection and
maintenance advice, the guidance is available to download at:
www.bossaccesstowers.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 within the 210mm range of the adjustable legs.
•Only components specified in this manual shall be used with BoSS 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.
•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.
| The assembled tower is certified to wind forces
equating to 27mph, but handling components under
those conditions would be hazardous.
| Also consider the wind funnelling effect of nearby
buildings.
•Towers greater than 8.2m platform height are for indoor use only.
•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.
