Common Problems

• Check that all the screws are right.

• Sometimes the motors won’t work properly if the potentiometer knob is between settings.

• The frame's brackets can be misaligned.

• Shaft sleeves can be misaligned.

• The tank stands and the posts are both adjustable, so their relative positions may need to be tweaked to prevent the rollers from sitting on the tank walls.
