1. Introduction
This service manual is intended as help in trouble-shooting, service and repair of the Ambu Man. It guides
you through a complete disassembly of the main parts, so that you will be able to replace defect or worn
parts.
The part list indicates the parts that we can supply. For practical or technical reasons some small parts
cannot be supplied as individual parts and you will therefore sometimes receive a whole set to replace the
defective parts.
The Ambu Man is updated on a current basis. Consequently, in such cases modifications will be forwarded
as supplementary pages for insertion in the manual.
Warnings
The Ambu man should only be repaired by persons with adequate knowledge. After each dis- and reassem-
bly the Ambu Man must be tested before it is put back into training.
For safety reasons only a specialist should repair the Ambu Defib Man with electrodes for defibrillation, as
some parts may be exposed to high voltage during defibrillation.
