Units are now dual handed and can be used in either the right or left side.
1. Select right (R) or left (L) handing for the sprocket and hoist as
needed.
• For JDC models, the drive sprocket can be mounted on either
the right or left side.
• For JHDC models with manual hand chain systems, the drive
sprocket can be installed as a right (R) hand or left (L) hand.
NOTE: The hoist will need to change location depending on the wall
mount or front of hood application shown in the images below.
• To reposition the hoist:
a. Remove the four allen bolts.
b. Pull the housing down and away from the motor, then rotate the housing 180 degrees.
c. Place the housing back up to the motor and tighten back in place using the allen bolts.

potential damage caused by an overhung load, position the sprocket as close to the center of the exposed drive
shaft.
