Cleaning

CLEANING

Model 1004 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 T rendelenburg (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 1004

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.

Cleaning

CLEANING (CONTINUED)

Hand wash all surfaces of the stretcher with warm water and mild detergent. DRY THOROUGHLY. Do n o t
steam clean, pressure wash, hose off or ultrasonically clean. Using these methods of cleaning is not recom­mended and may void this product’s warranty.

Suggested cleaners for stretcher surfaces:

Quaternary Cleaners (active ingredient − ammonium chloride)
Phenolic Cleaners (active ingredient − o−phenylphenol)
Chlorinated Bleach Solution (5.25% − less than 1 part bleach to 100 parts water)

Avoid oversaturation and ensure the product does not stay wet longer than the chemical manufacturer ’s
guidelines for proper disinfecting.

CAUTION

SOME CLEANING PRODUCTS ARE CORROSIVE IN NATURE AND MAY CAUSE DAMAGE TO THE
PRODUCT IF USED IMPROPERLY. If the products described above are used to clean Stryker patient care
equipment, measures must be taken to insure the beds are wiped with clean water and thoroughly dried fol­lowing cleaning. Failure to properly rinse and dry the beds will leave a corrosive residue on the surface of
the bed, possibly causing premature corrosion of critical components. Failure to follow the above directions
when using these types of cleaners may void this product’s warranty.

For mattress cleaning instructions, please see the tag on the mattress, or contact the mattress manufacturer.

Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate.
