How to install the clock chains
When you get the new unit, the chains may or may not be on the unit. Sometimes there just laying in the box and have bounced out of the movement during shipping. Just put them back on over the wheel with the hook side on the direction of the ratchet wheel you cant turn toward. In other words the hook is supposed to go on the weight, so that is the side that will not spin so easy on the ratchet wheel.
Put movement on the seat board with the chains hanging down in between the seat board as it was before. Screw the screws in and make it finger tight and then a little more with a flat screw driver.
