Erm, Ok.
Firstly motorise the dish to 42E. Keep everything done up tight. Then try tilting the dish up and down and see which way you have to tilt it to get a good signal.
Repeat for a western satellite such as 30W.
This will tell you if you are too low nearer the extremes, or too high. ( or even too low one side and too high the other)
N.B , you are not adjusting or changing anything at this stage, just 'flexing' the dish and mount a little, just don't get too heavy handed with it.
