Yes. Have you checked your manual? There are threads regarding play in the DG motors on this website. There are 4 screws on the motor that you need to loosen and tighten to get the proper tension to take out the play. Which screws, I don't know, that is why you need to look in your manual, or check here:
http://sadoun.com/Sat/Products/Power...ser_Manual.pdf and see the section for Adjust the Tube Loose. You can overtighten and the motor will not move, so be careful.

Sorry about that. That manual reference is from Sadoun's site. Sadoun obviously needs to update his resources on their site.
Is there a manual with that motor that explains tightening the loose tube?

Hello Vitru
Thanks for your replay, I hope Sadoun can give us an idea to us customers on how to fix this problem, the DG 280 has these adjustments, I would buy one of them, but I am not sure if it can handle a 1.2 meter dish, well hope Sadoun can see this post and give us any ideas. thanks again. Regards Paco

DG380 unable to handle FortecStar 120cm
I recently purchased a DG380 with a 120cm and tried to follow every instruction available, but I found several problems. The greatest problem is that the MKit5 (DG380 with 120cm) has trouble moving the dish when it reaches 30 deg East or West of 0. If I scan the dish to farthest horizon East, the dish will not return West because it's too heavy for the DG380. My lat/long is 31/97, but even with that SF95L I was not able to lock on a good signal zero quality either! Getting support was not easy...still have a wasted dish looking to the sky...maybe someone here might see my plight...stranded in centex.

now this may sound silly, might not even work but it's a thought I'm having. It's the engineer in me...
It might work, or it will be total failure :-) Problem - dish is too heavy for motor. Need to lighten dish's downward force on motor. Possible solution: Create a cantilevered arrangement to pull up on the top of the dish - take some load off the motor. Similar to below, but extend a pole up over the top of the dish and install a pully (so the support rope or wire can move). For the counterweight side, use a free hanging weight that can move up and down via the pully. This keeps constant tension on the top of the dish as it moves thru the arc.

Paco,
The DG380 has automatic backclash adjustment. How old is your motor? How heavy is your dish and LNBF?

When did you buy your motor? How heavy is your dish & LNBF?
