CPR PNEUMATIC CYLINDER (OPTIONAL)
Tools Required:
• Needle Nose Pliers
• (2) 1/2” Combination Wrenches
• 11/16” Combination Wrench
• Strap (or equivalent)
Procedure:
Note
Unless otherwise indicated, refer to Figure 17, page 1-59, for this procedure.
1. Raise the bed to the highest position and apply the brakes.
2. Remove the head section plastic cover (if equipped).
3. Unplug the power cord from the wall receptacle.
4. Using needle nose pliers, remove the rue ring, washer, two nylon washers and clevis pin (A, Figure 8, page 1-40)
connecting the head actuator tube to the seat section lever arms.
Note
Apply grease to the clevis pin and the nylon washers before reconnecting the actuator tube to the head section.
5. Lift the head section completely and secure it using a strap.
6. Using two 1/2” combination wrenches, remove the nut (H) from the bolt holding the lower end of the pneumatic
cylinder. Partially remove the bolt until the lower end of the cylinder is free. Keep the shoulder spacer/sleeve (I).
Disengage the lower end of the cylinder from the remaining sleeve.
7. Using an 11/16” combination wrench, loosen the lock nut (J) and unscrew the cylinder completely from the end
fitting (K). Note the location of the lock nut before loosening it so the new cylinder will be properly screwed into the
end fitting.
8. Reverse the above steps to install the new cylinder.
9. Test the CPR mechanism for proper operation before returning the bed to service.
