I had to be shown how to adjust the pitch on the awning of my A.C.E. 29.2. With the awning extended only about a foot or so, depress the spring loaded button and PUSH the lower slide arm up into the upper slide arm. I had been trying to move the upper (outer) slide arm down over the lower arm which meant I was pushing against the gas cylinder, a near impossible task. Spraying the slide arm with a lubricant of some sort would make the job a little easier as the arms fit very snugly with each other.
Setting the pitch to the next to last hole puts the awning down to provide adequate drainage as well as shade in the morning or late afternoon.
The awning will retract properly regardless of the pitch setting.
