1. Using the ratchet and ¼" socket, install the spring (K) and nut (J) on the
latch weldment (L). Tighten the nut to the bottom of the threads on the
latch weldment.
2. Assemble the main bushing release spacer (M), latch weldment (L), latch
guide (I), CPR release cable assembly (E), and the spring (K) as shown.
3. Attach the end of the spring (K) to the CPR release cable assembly (E).
4. Using the ratchet and ½" socket, install the two cable attachment screws
(G) and lockwashers (H) that secure the above assembly to the head drive
assembly (D).
5. Using the torque wrench, torque the two cable attachment screws (G) to
210 + 30 in-lb (23.7 + 3.4 N·m).
6. Install the pin (F) on the latch weldment (L).
7. Place the CPR release cable assembly (E) in position along the upper frame
and along the bottom of the siderail. Make sure the cable and ball are
properly seated in the CPR handle weldment.
8. Install loosely the cable adjusting nut (I) (see figure 4-4 on page 4-13).
9. Using the 5/16" Allen™ wrench, install the shoulder bolt (H) that secures
the CPR handle weldment.

cable clamps (B) that secure the CPR release cable assembly (E) to the
upper frame (see figure 4-33 on page 4-69).
11. Install the wire ties (C) along the upper frame. Cut the excess off of the
wire tie so it is flush with the lock mechanism.
12. While the siderail is in the down position, install a wire tie approximately
¾" (19.1 mm) from the wire jacket on both sides of the connector, and pull
the wire tie. Make sure a service loop of ½" (12.7 mm) exists in the electric
wire (K) before you tighten the wire tie (see figure 4-4 on page 4-13).
