If the motor stalls or the mount does not tracking smoothly, most likely the meshing is too tight. You
may loosen it by about 1/8 turn (or less for tracking).
Tighten the set screw in the small hole to LOCK the gear screw (important) before test the
mount.
Adjust again if needed, but no more than ¼ turn in total.
If you feel there is free play between the worm and gear, you may tighten the meshing adjustment
plunger to see if it can be eliminated. If not, contact iOptron for service.
NEVER turn the plunger all the way in. It may get gear switch stuck or damage the worm assembly.
