downloading manuals from this site

[mfred868]

I have been trying to download service manuals, they all seem to be rar type files, after ive decompressed them i get a message saying that they are corrupt and acrobat reader will not open.
is there anything im doing wrong? whats the best free decompressor for rar files?

i use rar 342 and most of the files works so try you too winrar 342
