Tighten both
NOTE: Good door balance and freedom of movement are critical to the safety and perfor- mance of the door opener. If door is very heavy to lift or if springs are too tight making door hard to close or if door sticks or binds in the track, now is the time to correct it.

WARNING FAILURE TO MAKE ADJUSTMENTS COULD RESULT IN SEVERE OR FATAL INJURY.
Once the alignment light comes on, tighten all bolts and mounting screws. Finish securing all wire making sure not to break or open any of the conductors. Loop and secure any extra wire.
