Just to add, why do you want this? Assuming that you are already certified, you should know almost everything in that manual well enough already. There may be a few things you want for handy reference, but I would think it would just be a few things.
Some people do not eat, drink and sleep diving. Some divers dive irregularly at best due to 'having a life'. I commend the OP for taking the informed decision to review the information in the OW manual. During the certification course (often around 4 days), it is impossible to absorb all the info given in manuals. This requires re-reading at a later date, when the info makes a bit more sense.
Unfortunately I very much doubt there will ever be a pdf. manual available soon from the 'main player' recreational diving agencies.
