REDUCED DRIVE CHAIN HOIST INSTALLATION INSTRUCTIONS (if applicable)
STEP 12 ALIGN THE SPROCKETS
Feed the hand chain through the pocket wheel assembly (installed in step #4),
around the cast iron hand chain wheel, and connect the two end links.
Align the chain hoist so that the 41B9 sprocket on the pocket wheel assembly is
in line with the 41A40 sprocket bolted to the barrel. Next, tighten the hoist-
locking bolts to lock the pocket wheel assembly to the shaft to prevent it from
shifting or rocking.
Hoist locking bolts must be tight to ensure hoist cannot shift
and permit roller chain to come off, thereby allowing door to
drop possibly causing severe injury or death.
Next, connect the #41 roller chain between the pocket wheel assembly sprocket and the barrel sprocket. Now run the
door up and down several times to ensure that the roller chain does not come off. If it does, go back and check the
alignment of the sprockets.
Keep loose clothing, fingers, hands, and arms away from all
moving mechanisms and places where chain meets either
sprocket, or serious injury or death could result.
STEP 13 INSTALL THE CHAIN KEEPER
Now install the hand chain keeper to the wall
approximately four feet above the finished floor with the
hardware provided. Refer to the figure in step #7 of this
manual for an additional view.
