If it is a ratchet-type wrench, its adjustment is automatic, you just have to place the three support points around the nut and turn to the right to lock the tool and tighten. If what you want is to unscrew, then you have to change the direction of the tool and turn to the left.

Next, it is advisable to lubricate the jaw adjustment mechanism, so that it regains smoothness, for this you can use multi-purpose spray or dropper oil.

Q4: Why does the wrench slip?

There are at least two ways to slip the wrench. The most common is due to an incorrect adjustment when controlling the mobile clamp to tighten the nut.
