 While winding the 7 foot high dyeing machine garage door spring, you must make  quarter turns and while winding 8 foot garage door springs you must turn 31 to 33 quarter turns. once this is done, you can check whether you have done a good job.To do this, lift the door all the way up past the top. Ensure that there is still some tension perceived on the cables. If the tension is inadequate, then you may probably need to wind the spring up by one or two more quarter turns. [Details]
