INJURY TO PERSONNEL.
(3)
Using a 7" minimum diameter of 1/8" thick
abrasive wheel that will clear adjacent
links, cut a portion out of the second to
last link (flat link) on loose end of load
chain (55). Center a 3/8" long cutout on
the weld of the link, to form a coupling link.
Remove and discard the last link.
(4)
Attach new load chain (55) to the old chain
with the coupling link just created. Ensure
that the first link of the new chain is an
upstanding link with the weld facing away
from the liftwheel (21).
(5)
Attach power cord to a 110 Volt power
source and operate the hoist in the DOWN
direction until approximately 2-1/2 feet of
new chain remains on the loose end side.
Disconnect power cord.
(6)
The last link on the loose end side of the
new load chain must be an up-standing
link. If last link is not an up-standing link,
cut it off using cutting procedure as
described in step 3, above.
(7)
Slide stop block (19) onto new load chain’s
last link and secure that link to loose end
block (16) with a new pin (18).
(8)
Attach loose end chain to motor housing
(56) with flat washer (12), lockwasher (13),
and capscrew (14).
