Running The 6690L After Full Service On My Door

Here I did a service on the Doorlink model 491 and I show how it runs after. The door was ever so slightly heavy so I add a little tension to the torsion springs. Now it just floats and remains neutral. DO NOT DO THIS IF YOU ARE NOT A TRAINED PROFESSIONAL I’M NOT LIABLE FOR ANYONE WHO ATTEMPTS THIS ON THEIR OWN.
