Excellent concise manual. All needed information was included. Typeface and diagrams were clear. Very fair price considering what others are charging. Many thanks
 ;
Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.
Overall- value for money- I recommend
;
Excellent quality and quickly delivered manuals at a fair price. Great care is taken in the reproduction process. Even photographs and highly detailed drawings are as clear as in the original. That cannot be said for some freelance manual copies I have obtained from the web. If you have exhausted your internet search of technical manuals, try Owner-Manuals.com. If they do not have it, I do not think it exists. Perhaps, if requested, they may be able to find it. Their resources are certainly greater than most. Shopping here certainly beats waiting for months or years for the manual you seek to appear in an internet auction or garage sale.
