I often have spare blades so a sharp one can be at the ready. If a blade is changed, even though they are of the same vintage, the lever screw may need adjusting. Usually only a sixteenth or so of a turn unless one is switching from a Stanley cap and blade to a Hock cap and blade.
Making Shavings
At this point, the blade is likely well below the sole of the plane. Retract the blade by turning the depth adjusting nut. Stanley planes made after 1891 will turn counter clockwise to lift the blade. Before we start, one needs to read the grain on the wood. Sometimes it will fool you, but most of the time, you will want the grain to rise in the direction you are planing. So find a piece of scrap 1X or 2X and clamp it in your vise. Start with the business part of the plane off the wood and just the toe (the part of the sole in front of the blade) on the work piece. This is how one usually starts a plane on a work piece. This is especially true when using a jointer. With a smoothing plane, one may at times just be working a small area on a large piece.

When it is flat on the wood and pushed forward, nothing should happen because the blade is retracted.
Some set their blades by sighting down the sole and turning the adjuster until they see the blade. When you get to wearing bifocals and your close up sight needs different glasses, you may want to find a different way. I am not knocking the sight set method. I envy those whose eyesight is still that good.
My method is to adjust the depth while pushing the plane on the edge of the scrap wood.

This plane is a type 6. The depth adjuster turns to the left to lower the blade. Shavings are just beginning to appear in the mouth.
At this point take a shaving on the one side of the plane and then the other to check the lateral adjustment.

Notice that the shaving on the left are visibly heavier than on the right. With the Stanley plane, the lever is moved to the side that is cutting heavier to even out the cut.

Notice that the blade is being held on both sides by my fingers. This is so that any movement can be felt. Over time, you will get used to feeling how much movement is needed. Though some times a blade that is not straight or other factors can make setting the lateral adjustment a pain in the tukus.
My preference is to set the lateral adjustment with very thin shavings. It just seems easier to tell if they are the same. After a bit of experience, you will likely be able to determine by feel if one side of the blade is cutting deeper than the other.

The shavings shown are for all purposes equal.
