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.
Clear Height Class (H1 = 1.85m, H2 = 1.90m) *UDL = Uniformly distributed load 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.
• 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.

Using the Tower Safety Checklist This inspection must be carried out before initial use, after moving the tower, if any environmental condition change that may affect the tower and at regular intervals determined by local regulations. Local regulations may also specify other information to be supplied to the user or attached to the structure.
The adjustable legs are for levelling the tower only. They must not be used to gain extra height. • Do not use boxes, stepladders or other objects to gain extra height. • Beware of horizontal forces that might cause instability. Maximum horizontal force = 30kg. BoSS Zone:1 Instruction Manual...
