Maintenance
9.5 inspecting the Chair
Have your service’s equipment maintenance personnel
inspect the chair at regular intervals. Conduct a visual
inspection of the track system before use, and a thorough
inspection of the track system after each use.
Follow the checklists on this page and work the chair
through all its functions as described in this manual.
If inspection shows damage or excessive wear, remove the
chair from service until repairs are made. See
Parts and
Service,
pages 44-45.
