Umarex Origin Trigger setup, How does the sear go in?

This is an Umarex Gauntlet trigger from Hajimoto's web site, but may be similar.
I have not had the trigger apart on my origin, so other than this, I can not provide any help.

The screw at the top left of the trigger frame that is backed all the way out is the sear engagement. By screing that in you will force the sear surface of the trigger to be much shorter. This is the classic Rem 700 trigger adjustment profile.. Top screw= sear engage,ment, middle screw= overtravel, bottom screw, ( not visible but accessible from the back of the rtigger guard) is the spring pressure..
