Procedure

1. To create a "C" link, cut the welded side of the link with a hack saw. Clamp one side of the "C" link in a vise and bend it open by using pliers to grip the exposed part of the link.
2. If you are replacing the hand chain, disconnect it at the "C" link and carefully remove the hand chain.
3. To replace chain: a. Cut a length of chain 2 times the required hand chain drop plus 1 foot (30 cm). b. Run the new chain up through the left hand chain guide, around the hand wheel, making sure the hand chain is seated in the hand wheel pockets, and back down through the right hand chain guide.
4. To adjust chain length: a. Add or remove a length of chain 2 times the desired amount of chain adjustment.
5. Connect the hand chain ends with the "C" link(s), make the total number of links even, and bend the "C" link(s) shut.
6. Make sure the hand chain is not twisted. To untwist, open a "C" link and remove one hand chain link.
