2. If replacing existing chain, remove chain block kit from
loose end of chain by removing the two (2) screws
from opposing sides of the block. Remove lower hook
assembly by removing the pin holding the chain into the
assembly.

3. Using a connecting link, attach new chain to the “loose
end” of starter chain (existing chain if replacing) and
guide through lower hook block, through upper sheave
hanger and over sheave wheel, through center hole

binds.
4. Place dead end link into dead end slot, and insert pin.
Attach loose end link to frame of hoist, using the provided
screw. Tighten all fasteners securely.
To attach the chain to the dead end block on Models E,
E-2, H, H-2, R, R-2 and RR-2, proceed as follows:
1. Suspend the hoist from an adequate support.
2. On Models E, E-2, H and H-2, insert the last link of the
load chain into the dead end block (1) and secure it with
the dead end pin, washer and cotter pin furnished with
the suspension. Ensure there are no twists in the chain.
3. On Models R, R-2, RR and RR-2, slide the contact block
up the chain until it is against the bottom of the hoist
and the dead end block is projecting through the square
opening in the bottom of the block. Insert the last link of
the load chain, making sure there are no twists between
the hook block and the dead end block, into the dead
end block. Push the contact block up slightly and secure
the load chain to the dead end block using the dead end
pin, washer and cotter pin furnished with the suspension.
The dead end pin also supports the contact block (See
Figure 8)

Do not remove the plastic ties from the load chain at this
time. After the suspension is installed, hoists with a hook
suspension can be suspended from its permanent support
and then connected to the power supply system (refer to
page 14). For hoists with a lug suspension that are to be
suspended from a Series 635 Low Headroom Trolley, attach
the hoist to the trolley per the following instructions.
