CAUTION: For a 2-Fall load block assembly, make sure the chain weld on chain link
faces away from chain wheel pocket on hoist and inward toward idler sprocket of
hook block assembly. See Figure 13 (drawing 2/2). Follow steps outlined below:
5. Run hoist “DOWN” in slow speed to feed chain through chain sprocket. Continue running until about
2.0 feet [60 cm] of chain is available out the other side.
6. Slide chain onto idler sprocket of load block making sure not to twist chain while inserting it. Link
weld must face inward toward the idler sprocket on load block assembly.
7. Attach chain anchor and chain to hoist body. Tighten chain anchor bolts per recommended torque
settings in Section 7.4.
8. Attach load block assembly on end of load chain. Attach fall stop at least 6.0 inches (150 mm) from
the end of the chain (on the chain container side). Refer to Figure 14 for details.
9. Make sure that chain is not twisted or kinked.
10. Attach chain container.
After chain installation:
1. Without a load, run chain up and down a few times to make sure load chain is not twisted. If so,
remove chain twist.
2. Lubricate load chain.
