Download the manual for Orbitor 6000 and see if it helps.
The general assembly and parts should be very similar.

Download the manual in the link below. It is for the Orbitor 6000 which is a 6" Netownian Reflector telescope on an equatorial mount. Your telescope may have a Alta-Zimuth (AZ) mount instead, then click on the second link for the Celestron 114AZ. Although the telescopes are different from yours, the basic parts are very much similar and these manuals could be of help to you.

Do you have a manual? If your telescope is a refractor (long narrow tube with a lens at the front and eyepiece focuser at the other end) then maybe the following manual for the Orbitor 1208ss will be helpful.

If your telescope is a reflector - has a mirror at on end and a focuser on the side of the tube at the other end then maybe the following manual for the Orbitor 6000 (Model 9000) will be helpful.

I have the ORBITOR 6000 telescope and the manual. I just uploaded the manual to the Orbitor Manuals section and they are reviewing it before they publish it on this website. Click on the link below to download the ORBITOR 6000 USER MANUAL:

All of Tasco's manuals are on this web site:

http://www.tasco.com/pages/instruction-manuals/

Here are the manuals for Orbitor. There is no manual for 5500, however they all assemble in the same way. Look through the list for one that is similar to your telescope.

Then READ my TIPS on my profile page; especially the frequently asked questions TIP.

You probably will not be able to find a manual. However Meade maintains a web site with all of their telescopes.

Look under either REFRACTOR or REFLECTOR for one similar to your telescope. They all assemble in a similar fashion and the Meade manuals have a section on how to use the telescope.\

Meade is very good on replacement parts - give them a call.
