Reassembly Notes
When replacing the rear rope tensioner, be sure that the tensioner spring
area is positioned so that it faces you. This ensures that the rope
tensioner is in the right position to fasten to the translate frame (see
Figure 5-33).
To give yourself enough slack in the , fasten the drive rope ends to the
rope tensioner before hanging the drive rope over the top two pulleys.
Before applying tension by setting the rope tensioners, insert the ropes
into the rope coupler and attach the coupler cover plate (see Figure 5-31).
