new safe

[kindnug420]

Just got a new safe, and it came with a preset combo that you need to do then you can set it to what you want. Problem is, im confused as fuck and cant get it going. The book says

4->-77
3-<-32
2->-81
--<--

What the fuck?

turn it four times right, stop on 77. 3 times left stop at 32, 2 times right stop at 81.

the last part i dont know.
