Hand Chain Adjustment or Replacement
CAUTION
•When cutting the weld side of a hand chain link, do not cut or nick the opposite side. A damaged link must be replaced to prevent premature failure. A falling hand chain can cause injury.
(Dwg. MHP0016)
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 a pliers to grip the exposed part of the link.
(Dwg. MHP0014)
2.If the hand chain is being replaced, disconnect it at the “C” link and carefully remove the hand chain.
3.When replacing a hand chain, cut a length 2 times the required hand chain drop plus about one foot (305 mm). For adjustments, remove or add a length of chain twice the difference in hand chain height. To prevent the hand chain from twisting, maintain an even number of links, by removing or adding an even number of links.
4.If you are replacing the hand chain, run the new hand chain up through the left hand chain guide, around the handwheel, making sure the hand chain is seated in the handwheel pockets, and back down through the right hand chain guide.
5.Connect the hand chain ends with the “C” link(s), making the total number of links even, and bend the “C” link(s) shut.
6.Make sure the hand chain is not twisted. If twisted, untwist or open a “C” link and remove one hand chain link. Refer to Dwg. MHP0015 on page 12.
