  • Page 14: Safety Information

    Safety Information Chapter 1: Introduction SAFETY INFORMATION Train and educate your staff on the hazards associated with electric beds. Do not allow persons to have their entire body below the sleep surface and within the confines of the bed. Unplug the bed from its power source, and put the lockout switch in the locked position before you clean or service the bed.

  • Page 15: Water Mattress

    Hill-Rom recommends the use of Hill-Rom® mattresses that have been designed and tested specifically for the bed. If you purchase a replacement mattress from Hill-Rom or another manufacturer, make sure that the safety features of the bed have been tested and verified to operate correctly with the replacement mattress.

    Chapter 6 Cleaning and Preventive Maintenance CLEANING WARNING: Follow the product manufacturer’s instructions. Failure to do so could cause personal injury or equipment damage. WARNING: Failure to unplug the bed could cause injury or equipment damage. WARNING: Do not expose the unit to excessive moisture which would allow liquid to pool. Personal injury or equipment damage could occur.

  • Page 190: Disinfecting

    ARING FOR THE OMPONENTS 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.

    Servicing the Bed Chapter 6: Cleaning and Preventive Maintenance SERVICING THE BED WARNING: Powered bed mechanisms can cause serious injury. Operate the bed only with persons clear of mechanisms. Failure to do so could cause personal injury or equipment damage. WARNING: Unplug the bed from its power source and put the lockout switch in the locked position during routine maintenance or cleaning.

    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.
