Page 14 Safety Tips Chapter 1: Introduction Brake and Steer Pedals Always keep the casters in the brake position when the bed is occupied. Patients often use the bed for support when getting in or out of bed, and serious injuries can result if the bed moves. After brakes are set, rock the bed gently to ensure that they are locked.
Page 15 Safety Tips Chapter 1: Introduction CPR Release Only healthcare professionals should use the emergency CPR release. The two release handles are located under the head section of the bed near the seat section. To activate the CPR release, pull the handle away from the bed. Continue to pull out on the handle until the head section is flat.
Page 16 Safety Tips Chapter 1: Introduction WARNING: Prop up the head section before removing the cotter pins and clevis pins. Failure to do so could result in personal injury or equipment damage. WARNING: You must use the 2" x 4" pieces of lumber to support the foot yoke. The foot yoke will fall during this procedure if not supported.
Page 17 Follow the product manufacturer’s instructions. Failure to do so could result in personal injury or equipment damage. WARNING: Adhere to the Infection Control Policies and Procedures from Hill-Rom. Failure to do so could result in the spread of infection. WARNING: Powered bed mechanisms can cause serious injury.
Page 18 Safety Tips Chapter 1: Introduction WARNING: Only facility-authorized personnel should perform preventive maintenance on the bed. Preventive maintenance performed by unauthorized personnel could result in personal injury or equipment damage. WARNING: Inspect the pivot point fasteners semi-annually. Failure to do so could result in personal injury or equipment damage.
Page 19 Safety Tips Chapter 1: Introduction WARNING: The voltage in the electrical system presents an electrical shock hazard. Perform standard electrical service procedures before attempting service within the P.C. board enclosure. Adhere to all electrical safety precautions when servicing the bed’s electrical system. Failure to do so could result in personal injury or equipment damage.
Page 20 Safety Tips Chapter 1: Introduction CAUTION: Remove the battery if the bed will not be in service for extended periods of time. Failure to do so could result in damage to the life of the battery, or damage to the bed. Contact the appropriate maintenance personnel. CAUTION: Do not position the head of the bed against a wall or beneath any fixtures.
Page 21 Safety Tips Chapter 1: Introduction CAUTION: For shipping and storage, place the removed P.C. board in an antistatic protective bag. Failure to do so could result in equipment damage. CAUTION: Support the siderail during the removal procedure. Failure to do so could result in equipment damage.

Page 281: Chapter 6: General Procedures
Chapter 6 General Procedures Cleaning WARNING: Follow the product manufacturer’s instructions. Failure to do so could result in personal injury or equipment damage. SHOCK HAZARD: Unplug the unit from its power source. Failure to do so could result in personal injury or equipment damage. SHOCK HAZARD: Do not expose the unit to excessive moisture which would allow liquid to pool.
Page 282: Cleaning Hard To Clean Spots
Caring for the Wood Components Wood is selected for use on beds because of its beauty and warmth. All Hill-Rom wood products are treated with a resin-based sealer and finish that provide resistance to abrasion, staining, and fluids. Many disinfectant/cleansers have a softening effect on any painted or finished surface if used in high concentrations.
Page 283: Servicing The Bed
Servicing the Bed Chapter 6: General Procedures The bed should be cleaned by wiping a soft dampened cloth over the surface, followed by wiping with a dry cloth. At no time should a wet cloth be allowed to lay on the surface. Any liquid spilled on the surface should be wiped up immediately.
Page 284: Component Handling
Component Handling Chapter 6: General Procedures Component Handling CAUTION: To prevent component damage, ensure that your hands are clean, and only handle a P.C. board by its edges. Failure to do so could result in equipment damage. CAUTION: When handling electronic components, wear an antistatic strap. Failure to do so could result in component damage.
Page 285: Lubrication Requirements
CAUTION: Do not use silicone-based lubricants. Equipment damage could occur. Hill-Rom uses maintenance-free DU bushings at major load and pivot points throughout the bed. These bushings are designed to run dry without lubrication. If the bushing squeaks during operation, apply anti-seize compound to its bearing surface.

Page 295: Using Loctite® Adhesive
Using Loctite® Adhesive Chapter 6: General Procedures Using Loctite® Adhesive The proper use of Loctite® retaining compounds during service is essential to enable certain fasteners to be correctly retained.
