8. Keep tension on the end of the new chain and
press the DOWN button on the controller, until
chain clears the hoist. Stop hoist when 1 to 2
feet of new chain remains on the slack side.
9. Install the limit block, spring and chain stop on
the slack end of the chain.
10. Install chain container, making sure to install the
self-locking nut on the screw. Do not fill chain
container by hand.
11. Remove load hook from old chain and install on
new chain end.
12. Test limit switches by raising and lowering hook.
Inspect chain for any signs of twist or binding,
and correct before continuing.
13. Lubricate new chain with light coat of oil.
13.1.3 Vertical and horizontal links
Vertical and horizontal are determined by the
relationship to the load chain sheave. Vertical links
will be guided by the center slit in the sheave.
Horizontal links will engage the oval pockets on the
sheave. See Figure 13-4.

13.1.4 Double fall chain hoists
1. Locate the flexible chain puller that was
provided with your hoist.
2. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.
3. Remove chain container.
4. On the slack end of the chain, remove the chain
stop, spring, and limit block (Figure 13-2). Keep
these handy for later re-installing.
5. Keep tension on chain and press DOWN on
controller until slack end of old chain comes free
of the hoist.
6. Insert chain puller through hoist as shown in
Figure 13-2.
7. Connect hook of chain puller to the link on new
chain (Figure 13-3) and move chain through
until sprockets are engaged.
The link on the load side
end must be a vertical link, as shown in
Figure 13-3. If it is a horizontal link, the chain
will have a twist in it.
8. Press DOWN on controller while pulling chain
through until it completely engages the sprocket
and emerges from other side. Do not let the
chain twist or bind as it is being pulled through
the hoist.
9. Keep tension on the end of the new chain and
press DOWN on the controller, until 1 to 2 feet
of new chain remains on the slack side.
