iOptron CEM26 User Manual

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 eliminate it.
To Adjust RA Gear:
The RA gear meshing adjustment plunger is located next to the RA Gear Switch. The adjustment is
same as that for DEC gear/worm.
DO NOT over tighten the gear meshing adjustment plunger to avoid damage it.
