Telescope Shroud Trouble? - compare spotting scopes nikon vs celestron

Okay, I recently bought a 10 "Dob SKYWATCHER bending as shown here: http://www.skywatchertelescope.net/swtinc/product.php?id=139&class1=1&class2=106

Now a thin veil AstroZap specifically for them. I had a telescope for Christmas, compared to areas already in operation, and is a big improvement on 3.5 MI-Meade. So now I try, the shroud of light, which had to do 2 people to attach to, but the rings in the cladding is not the screws to the collapse of the telescope. So I guess in the instructions, instant messaging, that:

1. Remove the upper tube assembly.
2. Slide the light over the mantle of reinforcing steel.
3. Insert the upper tube assembly.
4. Drag flush on KNOBS in the upper tube assembly and below the ON in the lower base of the tube.

I will try # 2 I unscrewed the 3 screws that have been around the top tube in the vicinity of the reinforcing steel, and the entire upper tube did not work. Now I'm in trouble, there are also 3 hexagonal objects on every bar arms, in fear, you screw with my hand because I break the fear that something wrong and then I fucking. I just need a little advice on what to do.
