1.1 Introduction
Please read this instruction manual carefully.
This instruction manual shall be available at the location of use of
this mobile access tower. Instruction manuals are also available to
download at www.bossaccesstowers.com.
This product shall only be used in accordance with this manual without any
modification.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY LEAD TO
DEATH OR SERIOUS INJURY.
Mobile access towers must always be used in accordance with the national
regulations. If any aspect of these instructions conflicts with local regulations, please
contact Werner UK Sales & Distribution Ltd. for advice.
Please note that diagrams are for illustrative purposes only.
User training courses are available but must not be used as a substitute for
familiarity with this manual.
A BoSS Zone:1 fibreglass mobile access tower is a safe and practical alternative
when other towers are not suitable for use, especially around electricity. They
provide indoor and outdoor access solutions where a stable and secure platform is
required. Ideal for maintenance and installation work or short-term access, the highly
versatile towers provide a strong working platform for a variety of heights.
Verification and assessment documentation is held by Werner UK Sales &
Distribution Ltd.

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 Fibreglass Tower 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.
•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 315mm range of the adjustable legs.
•Only components specified in this manual shall be used with BoSS Zone:1
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.
•Consideration should be given to potential wind conditions if the tower is left
unattended.
