Pearson P31-II User manual

November 22, 2002
For P31 owners who do not have the original owners manual, I felt that it was worthwhile to offer a copy of the on
that came with my 1991 P31-II #268. The dates on the pages and drawings imply that the manual was changed little
from 1998 on and is therefore applicable.
It also appears that Pearson used the same text for most of their manuals and inserted appropriate drawings for the
specific model being shipped. The general information should be useful to all Pearson owners.
The final page contains Keel Bolt torque values for Pearson Models 27 through P39
I used OCR (Optical Character Recognition) software to read the manual and convert it into Word 6.0. This allowed
me to keep the size of the file as low as possible for downloading. The pages that have drawings on them were
scanned as .bmp bit maps. These were inserted into the word document.
