Quote:The grinding noises are from the motor(s) binding up.
Quote:You can unscrew the chrome plated screw on the side and with a flashlight, visually check the mesh between the motor spur and worm spur. I use a single strip of paper inserted between the 2 gears. Press them together, tighten the motor mounting screw and using the NC, spin the paper out of the way. This is a good spacing for the gears.
