Adjusting manual steering box.

With manual steering, you should just need a slotted screwdriver and a box wrench. Loosen the large nut a bit w/ the box wrench first and while holding the nut steady, loosen the top adjusting screw 1/2 turn. Tighten the nut back down while holding the set screw. Road test and adjust again as necessary 1/2 turn or so at a time.

Make sure your front end is greased and suspension components aren't worn. Many times people will tighten the steering box to "try" and compensate for the "loose feel" that worn suspension pieces can cause.

For power steering, you'll need an allen wrench instead of a screwdriver.

Hope this helps.
