See
Timney Triggers, specifically the "Installation" page. Contact Timney if that doesn't give you the answer. Personally I won't mess with a trigger unless I can literally visualize it functioning in my head, eyes closed. Too great a potential for a tragedy.
For a safety check include rapping directly on the bolt handle and rear of the bolt with a rubber hammer, simulating a drop or a hard fall. Seems to be the most sensitive spots.

Re-read your post, looks like you have the instructions. If the instructions don't work for ya, gunsmith time. Not a big deal, NOBODY is good at everything.
