Caravan Blinds

Please could you advise me on how to retension the window blinds on a Coachman Mirage caravan.
Many thanks in advance for any help or advice you can give me.


On the left hand side of the blind housing, there should be 2 screws. These screws are for tensioning both the blind and the fly screen. I think the top screw is for the fly screen and the lower screw is for the blind. Turn the screw a couple of times in a clockwise direction and then try the blind again. If necessary turn the screw again but be careful not to overtighten the spring
