Hi anyone got any details how to adjust a Omnister awning , manual type . It sticks in the ends when trying to open & its difficult to lock in when closed . I have tried various ways to adjust the arms & also at either end of the awning where it locks in . I got it right so i thiough after travelling about 60km it wound out ok ,but on leaving the site it was a pain again to lock in & also the knuckle of the left arm didn't go right home in the centre manage to lock in enough to travel home . But would love some guidlines as to best way to adjust things . Googled it but nothing really informative came up. Anyone help please cheers Bill
