Tow persons, working on opposite sides, grab the lower 'V' in the center and step backward away from each other.
Open frame approximately half way. Place the tent fabric on the frame.
Standing in the center of opposing sides, grab the trusses to pull the frame out completely.
With one hand braced on the top corner, use other hand to push the black corner slides all the way up until the pull pin engages the lock hole. Repeat for all four legs.
Lift each leg and slide the lower leg extension out until the release pull pin snaps into the first hole.
Repeat step 5 for each leg of the tent. Use the other holes for height adjustment or leveling on uneven surfaces. For take down do opposite direction.
