Hi Marvin! Although I am not a Festool employee I think that I can answer this one for you.
Unfortunately there is not a supplemental manual for the OF1010.
One way of checking to se if a tool has one is to go to the Festool USA website and navigate to the tool you are interested in. Then over to the right under Product Manuals & Documentation there will be links to the Supplemental Manual, Owner Manual and other helpful resources.
