Carefully read and strictly follow the warnings and cautions listed on this page. Service only by qualified personnel.
WARNING
• Always apply the caster brakes when a patient is getting on or off the stretcher. Push on the stretcher to ensure
that the brakes are securely locked. Always engage the brakes unless the stretcher is being moved. Injury could
result if the stretcher moves while a patient is getting on or off the stretcher.
• Be sure the siderail latching mechanism is working properly at all times. If it is not, refer to your stretcher
maintenance manual for “Siderail Latch Adjustment”.
• When using the transfer board to transfer a patient, always lock the brakes on all stretchers, beds, etc. being used
and always be certain the transfer board is placed securely on the surface of the mating stretcher or bed. The
patient stretcher and the mating surface must be at the same height before the patient is transferred.
• The weight of the patient’s head is resting on the head piece and must be supported by the operator when the
latches are released and the head piece is being positioned. Failure to adequately support the head piece while
positioning the head could result in patient injury.
CAUTION
• To avoid damage, remove any equipment that may be in the way before raising or lowering the litter height.
• When lowering the siderail to the collapsed position, keep extremities of patients and staff away from the siderail
spindles or injury could occur.
• To avoid injury or damage to the equipment, do not allow the siderail to lower on its own.
• Operation of the pneumatic Fowler is a manual procedure. Use caution when raising the Fowler while a patient is
on the stretcher. Use proper lifting techniques and get additional assistance, if necessary. Failure to use proper
lifting techniques could cause injury to the operator.
• Keep hands/fingers clear of the area around the Fowler release handle and the Fowler frame when lowering the
Fowler. Injury could result if care is not taken when lowering the Fowler.
• Do not reach between the side of the head extension and the articulating head piece to pull the release handle.
Finger injury could result.
• To avoid possible pinch points when adjusting the head piece, keep your fingers away from the jointed areas.
• When the transfer board is being used to transfer a patient, the support post must be in the stored (down) position.
Damage to the support post will occur if it is pushed up against a stretcher, table, etc.
• If the stretcher is equipped with the optional foot end I.V. pole, the I.V. pole must be in the raised position when the
foot extension/defibrillator tray is installed. If the I.V. pole is not raised, the foot extension will not function properly
and injury could occur.
• If the stretcher is equipped with the optional foot end push handles, use caution while the foot extension/defibrillator
tray is installed to avoid pinching your fingers.
• To avoid damage while transporting the stretcher, verify the I.V. pole is at a low enough height to allow it to safely
pass through door openings and under light fixtures.
• To avoid damage, the weight of the I.V. bags should not exceed 40 pounds.
• The unit cannot be raised (hydraulics on base) with a patient lift under the stretcher.
• The hood may not be used for stepping.
NOTE
• Clean hood storage area regularly.
• The bottom of the brake pads should be cleaned regularly to prevent wax or floor remnant buildup.

STRETCHER CLEANING
These instructions are intended to provide recommended cleaning methods for the Stryker Model 1079 Eye Surgery
Stretcher. They outline proper care that will provide effective cleaning and disinfecting of stretchers between patients
and prolong the life of the stretcher.
RECOMMENDED CLEANING METHOD
Note: Follow the cleaning solution manufacturer’s dilution recommendations exactly.
• Remove the mattress prior to washing the unit; do not wash the mattress with the stretcher.
• Wipe the unit with cleaning solution and water per manufacturer’s recommended dilution.
• Dry thoroughly. Do not replace the mattress on the stretcher until the unit is completely dry.
• Before returning the unit to service, verify that all labels are intact and that the brake/steer pedal locks properly in
both positions and check all components for proper lubrication.
DO NOT STEAM CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN THE STRETCHER.
Using these methods of cleaning are not recommended and may void this product’s warranty.
RECOMMENDED CLEANERS
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 over saturation and ensure that 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
suggested above are used to clean Stryker patient care equipment, measures must be taken to insure the stretcher is
wiped with a damp cloth soaked in clean water and thoroughly dried following cleaning. Failure to properly rinse and
dry the stretcher will leave a corrosive residue on the surface of the stretcher, 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.

Cleaning
MATTRESS CLEANING
These instructions are intended to provide recommended cleaning methods for stretcher mattresses. They outline
proper care that will provide effective cleaning and disinfecting of mattresses between patients and prolong the life of
the mattress.
RECOMMENDED CLEANING METHOD
• Hand-wash all surfaces of the mattress with warm water and mild detergent cleaner.
• Dry thoroughly.
• Apply disinfectant solution either by spray, solution or pre-impregnated wipes (do not soak mattress).
• Clean per hospital protocol for bed mattresses.
• Wipe up excess disinfectant.
• Rinse with clean water.
• Allow surface to dry.
RECOMMENDED DISINFECTANTS
IMPORTANT: DILUTE ALL DISINFECTANTS IN ACCORDANCE WITH MANUFACTURER’S DIRECTIONS
When used in concentrations recommended by the manufacturer, diluted bleach, diluted phenolic, or diluted quaternary
germicidal disinfectants are recommended. Chlorine Bleach, typically 5.25% Sodium Hypochlorite, should be used at
a dilution ratio of 1 part bleach to 10 parts water.
RINSE OFF CORROSIVE CLEANERS
These products are NOT considered mild detergents. They are corrosive in nature and may cause damage to your
stretcher mattress if used improperly. Mattresses must be rinsed with clean water and dried thoroughly after using
corrosives such as quaternary, phenolic, or chlorine bleach. Failure to properly rinse and dry the mattress leaves a
corrosive residue on the surface, likely causing premature corrosion.
Iodophor type disinfectants are not recommended for use because staining may result.
The following table lists the recommended cleaner types for each mattress cover material (see definitions below):
Vinyl Mattress Cover Polyurethane Mattress Cover
Recommended Phenolics Quaternary, Quat/Isopropyl
Acceptable Quaternary, Chlorine Bleach (1:10) Chlorine Bleach (1:10)
Not Recommended Quat/Isopropyl Phenolics
Quaternary Cleaners: identified by ingredients containing the phrase “…yl ammonium chloride”
Quat/Isopropyl Cleaners: identified by a quaternary ingredient above plus isopropyl alcohol
Phenolic Cleaners: identified by ingredients containing the suffix “-phenol”
Chlorine Bleach: known generically as “Sodium Hypochlorite”

MATTRESS CLEANING (CONTINUED)
SPECIAL INSTRUCTIONS
Velcro To clean and disinfect, saturate with disinfectant, rinse with water, and allow it to evaporate.
Soils or Stains Use neutral soaps and warm water. Do not use harsh cleansers, solvents or abrasive cleaners.
Hard-To-Clean Spots Use standard household/vinyl cleansers and a soft bristle brush on troublesome spots or
stains. Pre-soak heavy, dried-on soil.
Laundering Laundering is NOT RECOMMENDED. Laundering may substantially decrease the useful
life of the mattress.
DO NOT STEAM CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN MATTRESSES.
Using these methods of cleaning are not recommended and may void this product’s warranty.
REMOVAL OF IODINE STAINS
1. Make a solution of 1−2 Tablespoons Sodium Thiosulfate in a pint of warm water and use it to wipe the stained
area. Clean the stain as soon as possible after it occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface before wiping.
2. Rinse surfaces which have been exposed to the solution with clear water before returning mattress to service.
Note: Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
