From the manual, it's a two person operation to roll up an electric awning manually. One person holds the strap while the other removes the pin from the motor end of the roller. Otherwise, the force of the awning rolling up when you pull the pin may knock you off the ladder. Once you have to roll it up manually, it's no longer useable until you get the motor problem fixed.
When my motor failed, it was already rolled up and would not extend. Couple of clicks and then nothing. Had to have the motor replaced (warranty).
