I bought a used Eagnas ST 250 from this forum, but the user manual/guide that came with the machine is for ST200. Can I donwload the user manual somewhere? Or how can I get one? Thanks!
Actually, you don't need the user guide. The mounting is very intuitive. What you need is an electronic tension calibrator to check the accuracy and consistency of the tensioner. Also, you need a key ring with a string attached and a starting clamp (don't use Eagnas's starting clamp).
I do not know how to do all the things you mentioned....that's why I was looking for a manual..... Is there any guidelines I can find online?
First, you have to mount the frame: http://www.eagnas.com/jpg2/st250ca3.jpg http://www.eagnas.com/st250.html Please post photos of the ST-250 with the frame mounted. To start main string, follow these instructions: http://badmintoncentral.com/forums/showthread.php?t=44504
there is a section in the manual of ST-200 (which you have on hands) talks about the calibration and how to use the tensioner. that part is the exactly the same as the ST-250. in order to do a good calibration, you need a tension gauge or a digital fishing scale (you can get one from Wal-mart). have fun.
If you are using an electronic calibrator or electronic fisherman scale, make sure the reading stays on for at least sixty seconds. You should watch the drop in tension. The resulting locked out tension should be slightly above the reference tension before the electronic gauge turned itself off.
As a rule of thumb, lock out tensioner pulls to the reference tension and locks out. After lock out, the string tension drops by approximately 3 lbs. Therefore, you have to adjust the latch cage and/or the tensioner spring & tensioner increment screw distance to compensate.
