• 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.

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 stabilizers).

• 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 funneling 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.
