7. Remove the screw and washer holding the

end chain to the hoist (Figure 10). Mount the

bracket of the chain container in that location

as shown in Figure 11.

8. Put the chain stop into the container (Figure

11), and operate the hoist to bring the load

hook up until the upper limit switch is tripped.

9. Check the chain to ensure that all the non-

loaded chain is completely in the container.

Do not put chain into the chain

container by hand! By not following the above

steps, the chain can become twisted or kinked

and can damage the hoist.

Pre-Operation Inspection

Inspecting the Load Chain

Clean the chain with a solvent, and carefully

inspect the entire load chain. Replace damaged

chain before using the chain hoist. See “Inspection

Procedures: Allowable Limits” on page 18 for the

maximum pitch allowed for chain length. If the

chain exceeds this amount, it must be replaced.

Also replace the load chain if any of the following

are identified:

1. Seriously rusted or cracked.

2. Marks on the chain surface are deeper than

5% of the link’s diameter.

3. Links are twisted or deformed.

4. The links are stretched too long or seriously

worn on the surface, especially at the points

where links contact each other.

Never extend load chain by welding a second

piece to the original.

Do not operate the hoist with a

twisted, kinked or damaged load chain. Do not

splice the load chain.

Check that the chain does not twist along its length

from hoist to hook. If twist is present on units with

multiple falls, the hook must be passed back

through the chain loop to remove all twist in the

chain.

The load chain supplied with

your JET chain hoist is designed,

manufactured, and tested for proper fit and
