Summary of Safety Precautions

Before operating this stretcher, it is important to read and understand all information in this manual. Carefully read and strictly follow the warnings and cautions listed on this page.

WARNINGS

Always apply the caster brakes when a patient is getting on or off the stretcher. Push on the stretcher to ensure 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 lowering the siderail to the collapsed position, keep extremities of patients and staff away from the siderail

• spindles or injury could occur. Keep fingers/hands clear of area around the Fowler release handle and the Fowler frame when lowering. Injury

• could result if care is not taken when lowering the Fowler. 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.

CAUTIONS

To avoid damage, remove any equipment that may be in the way before raising or lowering the litter height.

• To avoid injury or damage to the equipment, do not allow the siderail to lower on its own.

• The push handles were designed for use while transporting the stretcher. Avoid using other parts of the stretcher as

• push/pull devices because damage could occur. If the Pneumatic Fowler is difficult to operate, refer to the stretcher maintenance manual for “Pneumatic Fowler

• Adjustment”. To avoid damage, the weight of the I.V. bags should not exceed 40 pounds.

• 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. 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 rings should be cleaned regularly to prevent wax and/or floor remnant buildup.

Cleaning

Hand wash all surfaces of the stretcher with warm water and mild detergent. Dry thoroughly. Do not steam clean, pressure wash, hose off or ultrasonically clean the stretcher. 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 over saturation 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 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.

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. (Appropriate disinfectant for nylon Velcro® should be determined by the hospital).

FOLD DOWN SIDERAIL LATCH ADJUSTMENT

Tools Required:

1/8” Hex Allen Wrench

•

WARNING

The siderail latches are preset at the factory, and do not normally need adjustment. If adjustment must be done, it is important to follow the procedure below. If adjustment is not done properly, injury to the patient or user could result.

Procedure:

Using a 1/8” hex Allen wrench, adjust the hex Allen screw located on the latch assembly opposite the latch. Turning

1. the screw clockwise will decrease the amount of ”play” in the latching mechanism. Turning counterclockwise will

increase the amount.

Note

The amount of “play” in the siderail, when in full up engaged position, should be approximately 1/8 to 3/16 inches.

CAUTION

Too much “play” when the siderail is in the full up engaged position will give the siderail the appearance of being unstable and could also cause premature wearing of the latch system.

Too little “play” will obstruct the latch and keep it from engaging completely in the full up position, which may result in damage to the latch and/or injury to the patient or user
