The easiest way to remove the blower is to remove the air/gas channel
and blower as an assembly, then separate the blower from the assembly.
Because of the way the blower is mounted in the machine, it would be
very difficult to remove the blower from the machine directly.
Figure B19-1 shows how the parts are arranged.
