Jeff, Can't agree more with what was just posted. Several weeks ago I repaired a machine that I spent at least an hour wiping down because the adhesive spray acts light a magnet, attracting dust to it and to the machine. The cutout on the Z-index PCB , (A circuit board that is crucial to all the calibration aspects of the machine) had such a build up of lint and dust that it was no wonder the machine was not operating well. Establishing a Daily and Weekly General Maintenance Schedule is very important. Look the machine over, check your hoops for loose screws, are all the thread tubes connected to the back of the feeder rollers? Are there any cones of thread out of the tube and hanging there waiting to be wrapped up into the head or behind the rotary hook? A clean work environment and good ventilation will keep the lint and dust to a controllable level as well. Anyway suffice it to say that Jeff's comments are right on target. Very well put.
