I see someone said it's an Eastern arc, if you're looking for the satellites, you can use a compass with degrees listing numbers. You're looking for 155° and 171° and your dish should be level and 42° elevation with your skew set at 76° on the dish.
You can also use a western arc and look for 225°, 235°, and 245°. Those elevations range from 36° down to 24°. Your dish would need set with a skew of 124° and elevation of 31°.
Your best bet is to have two people, one to watch the sat meter on the TV, while someone is tuning the dish.
You will need a 7/16" wrench to loosen the adjustment bolts.
For an Eastern you want both the 61.5 and 72.7 to be in the 50's or higher
For a western the 119 and 110 to be 70's or higher and the 129 to be 55 or higher.
