Sounds like a component broken.

Unfortunately no manual is available online but if you contact http://www. synergyfitness. com.au/ they should be able to help you

adjust the Speed sensor, see the diagram, clean it, test for open or faulty, and tight the connector very well.
Lube the deck belt, see the video, lube the rollers bearing front+back too , test the drive belt motor and replace the belt if necessary. God bless you
However you must try to Run the software calibration after your fix it.

go to www.fitness.manualsonline.com and get it.

Hi I am using stex x6 machine 09 speed button not working

I am the same Problem with Stex 8020 T Error Code 1

If it reaches 250km then I suspect that the upper electronics is not functioning properly contact the distributor of Stex and If under warranty they sould cover it,but send out a servicer

To tighten the belt, start by locating the two bolts that adjust the rear roller (one on each side of the unit in the back). Run the unit at about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that what you do to one side, you MUST do to the other side or the belt will get off center. After you tighten it 1/4 turn, check the belt to see if it is still slipping. If it is then tighten the belt 1/4 turn again. Continue until the belt does not slip, but do not tighten the bolts more than 2 full turns.
As far as the manual, I have not been able to found it anywhere yet.
