我看了一下应该可以自己试试.
把门和opener脱开.再把门推到顶,固定好.There will be little torsion left at this time.轮盘是由两个螺丝固定在轴上的,拧松螺丝 轮盘就活动了.把钢丝卷回去.调一下位置."左侧的钢丝从轮盘中脱出来了"是位置不正造成的.拧紧螺丝,把门放下来,就行了.
门开着干,位置上不是很顺手.可还能够到. spring is not under torsion should be safer.

First you have find the exact reason why it is so tight. It may be caused by other reason. I adjusted my garage door two weeks ago. The problem was the door couldn't be closed even I turned the force to max. I released the door with the opener and checked the movement carefully. I found the reason was the track was not installed so vertically. When the door moved down to 1/3 postion, the door touched the track and got more and more friction. I adjusted the track and gave the door 1/2 cm more room to move. Now it moves smoothly and requires the opener small force.
BTW, don't take off the door and track for the adjustment! Loose some screws and use a hammer to adjust it.
