ENDRAIL CENTRAL COLUMN ASSEMBLY REPLACEMENT (CONTINUED)
4. Using a #2 Phillips screwdriver, remove the two screws (D) holding the lower end of the central column to the lower
structural member (E).
5. Using a #1 Phillips screwdriver, remove the eight screws (F) holding the top half of the upper plastic cover (G) to
the bottom half of the upper plastic cover (H).
6. Insert a small regular screwdriver between the two halves of the upper plastic cover to separate them. Use caution
to avoid scratching the covers or damaging the lower cover snap pins.
7. Lower the rail to the 14 in. locking position and place adjustable supports under the rail to support it when the
central column is removed.
8. Using a cordless drill and a #2 Phillips bit, remove the 14 screws (J) holding the upper end of the posts and the
central column to the upper structural member.
9. Using a 1/2 in. socket, remove the two bolts and two washers (L) holding the upper end of the two guide posts to
the structural member (K).
10. Remove the lower plastic cover.
11. Lift the defective central column to remove it. Use caution to avoid damaging the seal. Set the defective column
aside.
Note
The seal must be replaced if it is damaged during the procedure. Do not install a damaged seal.
12. Using a 3/32 in. Allen wrench, remove the set screw (A) holding the handle to the defective central column shaft.
Remove the handle and install it on the new central column, (see Figure 22,
13. Install the new column by first inserting the bottom end into the brake shoe and slide the column until the bottom
is seated in the cavity (W) of the lower plastic cover. Use caution to avoid damaging the seal while inserting the
column into the lower plastic cover. While the column slides though the brake shoe, rotate the handle to open the
lock stops (N) when the column reaches each of the fixed stops.
14. Install the remaining components in reverse order.
15. Check the stop catch positions and complete steps 16 to 21 if adjustments are needed.
Note
Proper adjustment centers the stop catches and evenly distributes the load of the rail. If the stop catches are not
centered they will rub against the plastic extrusion.
16. Raise the siderail to the upper position.
17. Using a #2 Phillips screwdriver, remove the two screws (O) holding the brake shoe cover (P) to the brake shoe
support (S) and remove the cover.
18. Using a 1/2 in. socket, loosen the two locknuts (Q) holding the brake shoe (R) to the brake shoe support (S) and
the two locknuts (T) holding the brake shoe support to the frame.
19. Move the brake shoe back and forth (head end to foot end) and the brake shoe support left to right to properly
position the stop catches (N). Tighten the locknuts.
20. If the stop catches still rub on the plastic extrusion, loosen the locknut (U) using a 3/8 in. combination wrench and
turn the adjustment screw (V) using a 3/32 in. Allen wrench until the proper alignment is achieved.
21. Verify the handle and four rail positions (lower, 9 in., 14 in., upper) for proper operation before reinstalling the brake
shoe cover and returning the stretcher to service.
