Stuck Awning

I tried to un-stow the A&E Awning on our rig but couldn't get to budge. Thought it had somehow stuck together from long dis-use. Brett, the local Mobile RV guy got it loose in a second. He advised that the last time awning was stowed it was allowed to slam shut which jammed the up/down mechanism. Moral, let awning roll up gently. BTW, A&E awnings do not need you to jerk the supports upward to release them at the top.
