Removal Procedure
The ends of the bellows are very sharp. Injury could occur if the bellows are not handled properly. Handle the bellows by the convolutions.
The bellows assembly must be supported always when the bellows assembly is not installed in the application. Failure to support the bellows assembly adequately could result in the failure of the bellows assembly. Do not use power tools to disassemble or assemble any part of the flexible exhaust system.The alignment of the bellows assembly is important. Incorrect alignment may lead to premature failure of the bellows assembly. Misalignment can be identified by visually inspecting the uniformity of the spacing between the convolutions on the bellows assembly.Inspect the bellows assembly for damage prior to installation. If there is any damage to the convolutions, discard the bellows assembly. If there is any difficulty in installation after the repair, discard the bellows assembly.
