describe potential serious adverse reactions and safety hazards.
CCAAUUTTIIOONN -- Alerts the reader of a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury to the user or patient or damage to the product or other property. This includes special care necessary for the safe
and effective use of the device and the care necessary to avoid damage to a device that may occur as a result of use or

Always read and strictly follow the warnings and cautions listed on this page. Service only by qualified personnel.
WWAARRNNIINNGG
• Do not clean, service, or perform maintenance while the product is in use.
• Do not steam clean, pressure wash, hose off, or ultrasonically clean mattresses. These methods of cleaning may void
the product’s warranty.
• Do not immerse the mattress in cleaning or disinfectant solutions. Excess moisture could cause product malfunction that
results in product damage or patient injury.
• Do not allow fluid to pool on the mattress. Fluids can cause corrosion of components and may cause the safety and
performance of this product to become unpredictable.
• Always inspect mattress covers for tears, punctures, excessive wear, and misaligned zippers every time you clean the
covers. Remove and replace a damaged mattress to prevent cross-contamination.
• Always disinfect the mattress between patients. Failure to do so could result in cross-contamination and infection.
• Always use two people to perform this procedure.
• Always remove the litter and the base hood before you begin to service jacks. Operator injury or equipment damage may
occur.
• Always lower the jack rod to the lowest position to relieve pressure on the pump piston side of the jack to avoid hydraulic
fluid loss or product damage when the base plugs are removed.
• Always make sure that both siderails latch in both the high and low positions to avoid injury to the patient or operator.
Make sure that the release handle is lubricated. Make sure that the dowel pin through the sides of the siderail is secure.
• Always put the product into the proper mode to avoid release of the foot cylinder, which may cause injury to the operator
or damage to the product.
CCAAUUTTIIOONN
• Improper usage of the product can cause injury to the patient or operator. Operate the product only as described in this
manual.
• Do not modify the product or any components of the product. Modifying the product can cause unpredictable operation
resulting in injury to patient or operator. Modifying the product also voids its warranty.
• Some cleaning agents are corrosive in nature and may cause damage to the product if you use them improperly. If you
do not properly rinse and dry the product, a corrosive residue may be left on the surface of the product that could cause
premature corrosion of critical components. Failure to follow these cleaning instructions may void your warranty.
• Do not let the pump piston come out of the jack or damage may occur.
• Only use Mobil Aero HFA hydraulic fluid. Using other types of oil may damage hydraulic units.

The life of the mattress can be affected by an increase in frequency of usage, which might include more frequent cleaning
and disinfection.
1. Use a clean, soft cloth to wipe down the entire mattress with a mild soap and water solution to remove foreign material.
5050-109-002 Rev A.2 11 EN

2. Wipe down the mattress with a clean, dry cloth to remove any excess liquid or cleaning agents.
