Warning/Caution/Note Definition The words W A R N I N G , C A U T I O N , and N O T E carry special meanings and should be carefully reviewed. WARNING Alerts the reader about a situation which, if not avoided, could result in death or serious injury. It may also describe potential serious adverse reactions and safety hazards. CAUTION 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 misuse. N o t e - Provides special information to make maintenance easier or important instructions clearer.
Summary of safety precautions Always read and strictly follow the warnings and cautions listed on this page. Service only by qualified personnel. WARNING • Always keep your hands clear of the red safety bar pivots when you load, unload, or change the height position of the cot. • Always use both hands when transporting the cot. • Always relieve pressure before you disconnect hydraulic or other lines. Escaping fluid under pressure can penetrate the skin and cause serious injury. Tighten all connections before you apply pressure. If an accident occurs, see a doctor immediately. • Do not use bare hands to check for hydraulic leaks. CAUTION • 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. • Always use authorized parts to avoid the risk of product damage. • Always check hoses and lines regularly to avoid damage to the cot. Check and tighten loose connections. Hydraulic lines, hoses, and connections can fail or loosen due to physical damage, kinks, age, and environment exposure. • Do not tip the cot onto its load wheels and actuate the product as this will allow air to enter the hydraulic system. • Do not lubricate the bearings in the X-frame as it will degrade the performance of the cot and may void its warranty. • The use of accessories, transducers, and cables, other than those specified or provided by the manufacturer, could result in increased electromagnetic emissions or decreased electromagnetic immunity and result in improper operation. • The emissions characteristics of this equipment make it suitable for use in industrial areas and hospitals (CISPR 11 class A). If it is used in a residential environment, for which CISPR 11 class B is normally required, this equipment might not offer adequate protection to radio frequency communication services. The user might need to take mitigation measures, such as relocating or reorienting the equipment. • Portable RF communications equipment, including peripherals such as antenna cables and external antennas, should be used no closer than 12 inches (30 cm) to any part of P o w e r - P R O and S M R T charger, including cables specified by the manufacturer. • Avoid stacking or placing other equipment adjacent to P o w e r - P R O and S M R T charger to prevent improper operation of the products. If such use is necessary, carefully observe P o w e r - P R O and S M R T charger and the other equipment to make sure that they are operating properly.

Product description The Stryker Model 6550 P o w e r - P R O ™ TL cot is a powered ambulance cot that consists of a platform mounted on a wheeled X-frame designed to support and transport a maximum weight of 700 lb (318 kg) in pre-hospital and hospital environments. The device is collapsible for use in emergency vehicles and the NiCd battery-powered hydraulic lift system allows operators to raise and lower the cot using the powered controls. The cot is equipped with a manual back-up release handle to allow the operation of cot functions in the event of power loss. The device is equipped with the following: retractable head and foot sections to reduce foot print and allow the cot to maximize maneuverability in tight spaces, siderails, patient securement straps, an adjustable pneumatic backrest and various optional accessories that assist with transport of the patient. Maximum patient comfort is attainable with the three different litter positions of shock, flat leg, and optional knee Gatch positioning. The S M R T ™ power system consists of a S M R T charger and a S M R T Pak. The S M R T Pak powers the hydraulic lift system of the Stryker powered ambulance cots.
Indications for use The Stryker P o w e r - P R O TL is a powered wheeled stretcher that is intended to support and transport the entire body of a traumatized, ambulatory or non-ambulatory human patient (includes infants and adults). The battery-powered hydraulic lift system helps to reduce the effort required by the operator to raise and lower the cot. The device is made to support patients in a supine (horizontal) or sitting position and to facilitate the transportation of associated medical equipment (such as oxygen bottles, monitors, or pumps) in emergency or transport vehicles. This ambulance cot is to be used in pre-hospital and hospital environments, in emergency and non-emergency applications. It is rated to a maximum capacity of 700 lb (sum of the patient, mattress and accessory weight) and the intended operators of the device are trained professionals, including emergency medical service and medical care center personnel, as well as medical first responders. P o w e r - P R O TL is not intended for extended stay or use as a hospital bed or in devices that modify air pressure, such as hyperbaric chambers.

Expected service life P o w e r - P R O has a seven year expected service life under normal use conditions and with appropriate periodic maintenance. The S M R T charger has a seven year expected service life under normal use conditions and with appropriate periodic maintenance. The S M R T Pak battery has a two year expected service life under normal use conditions.
Disposal/recycle Always follow the current local recommendations and/or regulations governing environmental protection and the risks associated with recycling or disposing of the equipment at the end of its useful life.

Preventive maintenance WARNING • Always relieve pressure before you disconnect hydraulic or other lines. Escaping fluid under pressure can penetrate the skin and cause serious injury. Tighten all connections before you apply pressure. If an accident occurs, see a doctor immediately. • Do not use bare hands to check for hydraulic leaks. CAUTION • Always use authorized parts to avoid the risk of product damage. • Always check hoses and lines regularly to avoid damage to the cot. Check and tighten loose connections. Hydraulic lines, hoses, and connections can fail or loosen due to physical damage, kinks, age, and environment exposure. • Do not tip the cot onto its load wheels and actuate the product as this will allow air to enter the hydraulic system. Establish and follow a maintenance schedule and keep records of the maintenance activity. Remove product from service before you perform the preventive maintenance inspection. You may need to perform preventive maintenance checks more often based on your level of product usage. Service only by qualified personnel. When using maintenance products, follow the directions of the manufacturer and reference all material safety data sheets (MSDS).
Lubrication The cot has been designed to operate without the need for lubrication. C A U T I O N - Do not lubricate the bearings in the X-frame as it will degrade the performance of the cot and may void its warranty.
Regular inspection and adjustments The following schedule is a general guide to maintenance. Factors such as weather, terrain, geographical location, and individual usage will alter the required maintenance schedule. If you are unsure how to perform these checks, contact your Stryker service technician. If you are in doubt as to what intervals to follow to maintain your product, consult your Stryker service technician. Check each routine and replace worn parts if necessary.
