CAUTION
• Do not distort the link in any manner. It must be able to
pass over the pocket and idler wheels without binding.
7.
Connect the new chain to the old chain by hooking the end
of the new chain onto the 'C' link. Make certain the welds
and links on the new chain match the positioning of the
welds and links on the chain being replaced.
CAUTION
• Ensure that chain does NOT become twisted during
reeving. All chain welds must align while chain is hanging
free.
8.
Slowly run the hoist in the raise direction, running off the
old chain and reeving the new chain over the chain wheel.
The first link of new chain over the chain wheel must be a
standing link. Refer to Dwg. MHP0472.
(Dwg. MHP0472)
9.
Reinstall the load hook and chain stopper.
WARNING
• A twisted chain can jam as it passes over the pocket wheel,
possibly resulting in damage to the hoist or even breaking
the chain and causing injury.
