Pattern Help + sign in pattern?

I've come across something I haven't seen and hoping someone can help. Here is part of the pattern and what I don't understand is the "+" in row #3:

(Multiple of 8 sts + 3)
Also see Chart.
Row 1: K2, *k2tog, k1, yo, k1, yo, k1, ssk, k1; rep from * across to last st, k1.
Row 2 and all WS rows: Purl.

Row 3: K1, k2tog, *k1, yo, k3, yo, k1 +, dcd; rep from * across to last 3 sts,
ending last rep at +, ssk, k1.

Can someone let me know what this means?
