and the angle indicators show that the apparatus is within the safe level range in slope and grade.
6. Push and hold the Level Assist Button until the truck auto-levels and all the stabilizers stops moving.
7. If the apparatus will NOT level within the safe range of the angle indicators in slope and grade using the Level

and grade using the Level Assist Button, proceed to step 9.
