two strong friends or more
Operating a gin pole is more complicated that raising the mast on your boat. Everyone has different attachment points, so no Two are alike.
I recommend you and two strong friends or more to muscle the mast up a couple times till you understand what goes on with everything during the lift. Damage to the boat and fittings can be possible by using some kind of lifting device by using the power of the device to bend or brake something not knowing. When muscleing, go very slow checking every cable attached to the mast and attached to the hull, that is why I suggest two strong friends or more.
Stays 2 and 3 on both sides and the backstay, stay attached. Stays 1 and the forestay are attached when the mast is vertical. Loosening of the backstay and stays 3 may need to be loosened at the deck fittings to get the three forward stays attached. Never need to adjust the stay number 2 that go all the way to the top of the mast.
When using a gin pole or any other device to lift the mast have those two strong friends or more around because if something happens it will happen when it can do the most damage!
