Cleaning CLEANING Model 1015 stretchers are designed to be power−washable. The unit may show some signs of oxidation or discoloration from continuous washing. However, no degradation of the stretcher’s performance characteristics or functionality will occur due to power washing as long as the proper procedures are followed. S

Follow the cleaning solution manufacturer’s dilution recommendations exactly.

S

Remove the mattress prior to washing the unit; do not wash the mattress with the stretcher.

S

Position the Fowler at 45_, place the unit in full reverse Trendelenburg (foot end down), raise the siderails, and place the I.V. poles and push handles in the up position.

S

Stryker Medical recommends the standard hospital surgical cart washer for power washing Model 1015 stretchers.

S

Do not replace the mattress on the stretcher until the unit is completely dry.

S

Before returning the unit to service, verify all labels are intact, verify the brake/steer pedal locks properly in both positions and check all components for proper lubrication.

DO NOT STEAM CLEAN THE UNIT. Use a maximum water temperature of 180_F/82_C. Maximum air dry temperature (cart washers) is 240_F/115_C. Water pressure − 1500 psi/103.5 bar. If a hand held wand is being used to wash the unit, the pressure nozzle must be kept a minimum of 24 inches/.61m from the unit. Stretchers must have maintenance performed after a minimum of every fifth washing. Refer to the maintenance manual for specific lubrication instructions. Failure to comply with these instructions may invalidate any/all warranties. Do not use abrasive cleaners to clean the display enclosure for the optional scale system. Do not allow cleaning solutions or other fluids to pool on the display unit. Wipe dry all surfaces after spills or cleaning.

Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% Sodium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach to 100 parts water are not considered mild detergents. These products are corrosive in nature and may cause damage to your stretcher if used improperly. If these types of products are used to clean Stryker patient handling equipment, measures must be taken to insure the stretchers are rinsed with clean water and thoroughly dried following cleaning. Failure to properly rinse and dry the stretchers will leave a corrosive residue on the surface of the stretcher, possibly causing premature corrosion of critical components. NOTE Failure to follow the above directions when using these types of cleaners may void this product’s warranty.

REMOVAL OF IODINE COMPOUNDS This solution may be used to remove iodine stains from mattress cover and foam footrest pad surfaces. 1. Use a solution of 1−2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area. Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to soak or stand on the surface. 2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.
