 Attach the Strain Relief Wire (2) to Cable Support L (1).
2.) Dual Speed Cylinder Model (DA)
 Refer to Figure 3-5.
 The Coiled Push Button Cord is factory installed onto the hoist body.
 Attach the Coiled Push Button Cord to the Chain Container with the Wire Tie provided, so
that the Load Chain hangs in the center of the Coiled Cord and the clamp part of the Wire
Tie faces up and away from the Load Chain.
