The tech that serviced your door must not understand simple mechanics. The tracks do not move, so they do not need to be lubricated. All that does is make a mess. The rollers and hinges DO move, so it is logical to lubricate them, at the hinge barrel or pivot point, and in the little area near the stem of the rollers where you can see the bearings. Adding a bit of lube to the torsion spring also cuts down on the friction between the coils and makes the spring glide easier. However, too much will make it spritz out lube as the door opens and closes, and that it less than desirable. Same thing for pulleys on an extension spring door.
Should an object or individual become trapped, or if a malfunction occurs, pulling on the handle will allow the user to manually lift the door up or down. If a garage door is good working order, the spring system that runs across the top of the door opening should provide enough assistance so an average adult can lift the door with relatively little effort.
