COUNTERBALANCE SPRING REPLACEMENT
COUNTERBALANCE SPRING KIT #88–0316–17–00
Required Tools:
Blade Screwdriver
Replacement Procedure:
1. Raise bed to full up position.
CAUTION
Disconnect power plug from wall receptacle.
2. Remove headboard, foot mattress, foot extension, foot pans, I.V. pole and leg supports.
3. Set brake with casters turned as though the bed is being pushed backwards. The casters at the head end
of the bed must be five feet away from the wall.
4. With the assistance of another person, lift the foot end of the bed chassis and rotate the rear casters until
the upper frame–headboard mounts touch the floor.
5. Remove the retaining clip wire off each of the two ball joint sockets of the defective spring.
6. Use the blade screwdriver to pry the socket off the ball joints and remove the faulty spring. To verify spring
is defective, hold large end firmly in your hands, place the small end on the floor, and push down. If the
spring collapses, the spring is defective. If it is not defective, remove the other springs and test.
7. Install the replacement spring by snapping the sockets on the ball joints and installing the retaining clip wire
through the ball joint socket.
NOTE
Be sure to install the spring in the same direction it was prior to removal.
8. Be sure all screws, cables and electrical connections are secure.
9. With the assistance of another person, tilt the bed back down to the floor.
10. Plug the power cord into the wall receptacle. Run through all functions on the hand pendant at least three
times to ensure proper operation. Check for proper cable routing and attachment to prevent interference.
11. Check electrical safety in conformance with specified hospital requirements (leakage current, ground conti-
nuity, etc.)
12. Remount all items removed in step two and return bed to service.
