5. Check that the chain is not twisted at the
bottom hook. All welds should face the same
direction (Figure 4).
Figure 4
6. For hoists with two or more falls of chain, make
sure the bottom hook is not capsized (turned
over). This may cause the chain to twist.

Raising the Load
To raise load, pull right side of hand chain (A,
Figure 5) so that wheel turns clockwise.
To lower load, pull left side of hand chain (B,
Figure 5) so that wheel turns counterclockwise.
Important:
Make sure hoist has an adequate
length of load chain to raise or lower the load in a
safe manner. Do not attempt to lower hoist beyond
its limit.

Hand chain: Cutting
and installing
To cut hand chain in order to lengthen or shorten:
1. Insert one link lengthwise into a vise (Figure
6). Be sure that the side opposite the weld lies
completely below surface of vise jaw (about
1/3 of a link). This prevents nicking or cutting
the lower part of the link.
Figure 6
2. Using a hack saw, cut through upper part of
link at the weld.
3. Loosen the link, reposition link vertically at
edge of vise with the level of the cut above the
vise jaw (Figure 7).

4. Tighten
vise
jaw.
5. Using an adjustable wrench, twist the link
horizontally from front to back. (Figure 8)
Open just far enough to insert (or remove) a
second chain link.
Figure 8
Note:
Chain length is now ready to lengthen or
shorten.
6. Insert (or remove) the second end link at the
opening in the first end link.
7. Using an adjustable wrench, twist the link
horizontally until the link is in the original
closed position. See Figure 9.
