To set the dish to point up to the satellites, you'll first need to set the elevation. Then you'll point the dish in the proper left-to-right position, to set the azimuth. You'll need to refer to the installation manual for your system for detailed instructions, but here's the short course.
Setting the Elevation (UP), (DOWN):
You can set the proper elevation after the dish is securely mounted. First, loosen the nuts securing the two elevation bolts so that the dish easily moves up and down. Line up the elevation indicator with the tick mark corresponding to your elevation number. Then tighten the bolts. You may need to readjust the elevation up or down slightly to get the best signal.

Moves dish up/down
Setting the Azimuth (LEFT), (RIGHT):
Loosen the azimuth nuts on the LNB arm enough that the dish can be turned smoothly with little pressure. Set the azimuth by moving the dish left and right. Point the dish in the general direction of the satellite, in the southern hemisphere. By using a compass you can better pinpoint the direction with your azimuth number to correspond with the degrees on your compass.

Setting the LNBF Polarization Tilt (Skew):
The LNBF and/or its bracket (s) are marked in degrees to indicate the polarization tilt or the (SKEW). The proper skew varies with location but within plus or minus 30 degrees in the USA except for Hawaii where the skew is minus 65 degrees.The 30 degrees equals 5 Minutes on the minutes scale of a regular clock. The 30 degrees also equals One Hour on the hours scale of a regular clock. The feed cable at the bottom of the LNBF is usually used to indicate the 6 O'clock mark when it is vertical.
Generally the skew is zero if you are in Huston, Texas. At the West States like California the skew could be as minus 30 degrees ( Clockwise rotation which equals to 7 O'Oclock of the feed cable when looking toward the Dish). In Maine the skew could be up to plus 30 degrees ( Counter Clockwise rotation or 5 O'clock if looking to the Dish). Looking at the Satellite(reversing the looking direction) the skew for California will be 5 O'clock and for Maine it will be 7 O'clock. During the final tune up phase, the LNBF should be rotated in both directions to optimize the signals and/or the quality levels.
