Introduction Overview The Cardiac Stress Treadmills are heavy-duty medical treadmills designed specifically for stress test applications.
Treadmill Configuration Treadmill Configuration The following illustration shows a typical treadmill configuration. 1 2 3 4 Figure 2-1: Example of a Treadmill TM 55/65 Treadmill 4.
Introduction Treadmill Controls Power The circuit breaker located on the front of the treadmill hood, controls the power to the treadmill (see item 1 in Figure 2-2). The circuit breaker must be set to ON for the treadmill to run. As long as the treadmill is plugged into a powered socket and the circuit breaker is set to ON, the treadmill is receiving power, even when the monitoring system power is turned off. ! WARNING! Danger of electric shock.
Operation Operation All patient data displays on the monitoring system screen. Use the operator manual supplied with the monitoring system for instructions on how to control the treadmill. Emergency Stop Button If the treadmill is equipped with an optional emergency stop button, it is located on the front handle bar. Pressing the emergency stop button causes the treadmill to stop sending power to the belt drive motor and the grade motor. Note: The emergency stop button is intended only for emergency use.

3 Operating the Treadmill The stress test monitor controls all treadmill operation. Please read the following treadmill-specific information, then refer to the operator manual supplied with your stress test monitor for operational procedures. TM 55/65 Treadmill 4.
Operating the Treadmill Guidelines for Safe Operation Keep the treadmill area clear. Maintain a minimum open space of 1.5 feet (0.5 meter) on each side and 6 feet (2 meters) at the rear. Before using the treadmill, verify that the correct cable connects the treadmill to the monitoring system. Do not start the treadmill when someone is standing on the belt. Never place chairs or other objects on treadmills. Do not leave a patient unattended on the treadmill.
Instructing the Patient Instructing the Patient 1. Before each test, describe the complete procedure to the patient: • Remind the patient to not use the handrail for support during the exercise unless absolutely necessary. Explain that gripping the handrail can affect the accuracy of the test measurements. • Describe how you will change the belt speed and treadmill grade during the test. 2. Demonstrate how to get on and off the moving belt: a.
Operating the Treadmill Starting the Exercise To start the exercise: 1. Start the treadmill walking belt while the patient stands on the side of the deck or straddles the walking belt. ! WARNING! Risk of injury. Do not start the belt while someone is on the treadmill belt. 2. Set the speed and grade to the minimum settings. 3. Have the patient step onto the treadmill as previously instructed. 4. Before changing speed or grade, inform the patient of the change.
Ending the Exercise Ending the Exercise 1. Tell the patient when the test is about to end. 2. Decrease the speed and grade gradually to minimum settings. 3. Before stopping the walking belt, tell the patient to grasp the handrail for balance. 4. Stop the walking belt. 5. Tell the patient to hold the handrail and step off to the side. ! WARNING! Unsteady patient. The patient may be slightly unsteady for several seconds after stepping off the walking belt. TM 55/65 Treadmill 4.

TM 55/65 Treadmill 4.
Maintenance/Troubleshooting Daily Visual Inspection Check the following items daily: Inspect the treadmill power cord and walking belt for wear. Check the position of the walking belt; be sure it is not rubbing against the frame. It should be centered on the deck within 0.25 inch of the sides; adjust if necessary. Check the handle bar and optional attachments to be sure they are fastened securely. Remove potential hazards from the treadmill area. 4-2 70-00297-01 A TM 55/65 Treadmill 4.
Cleaning Cleaning Exterior ! WARNING! Electric shock hazard. Turn off the treadmill and unplug the power cord from the wall outlet before cleaning. Daily Keep the treadmill free of dust and debris. Clean the exterior and walking belt with a damp sponge; do not soak surfaces. Dry all surfaces thoroughly. ! Caution. Damage to exterior. Never wipe the deck beneath the belt, even when changing the belt. Wiping can damage the wax finish. Do not use detergents or cleaning agents on any part of the deck.
Maintenance/Troubleshooting Adjustments Tools Required: Hex wrenches Phillips screwdriver Torque wrench ! WARNING! Catching of clothing. Secure long hair and loose clothing before using the treadmill or working near the treadmill walking surface or pulleys. Belt Tension Adjust the belt tension whenever the belt slips or moves unsteadily during operation: 1. Use the controls on the monitoring system to start the treadmill at minimum speed and grade, then increase the speed to 2.5 mph. 2.
Adjustments 4. Turn both adjustment bolts clockwise 1/4 turn. Test the belt tension as in Step 2. Repeat if necessary until the belt runs smoothly without slipping. If more than three adjustments are necessary, call an authorized technician. ! Caution. Belt damage. Do not overtighten the walking belt. Overtightening can damage the belt and rollers. Do not torque adjustment screws beyond 80 in/lb (9 Nm) maximum. 5. Stop the treadmill. 6.
Maintenance/Troubleshooting Belt Tracking Perform this procedure whenever the belt moves to one side or the other. ! WARNING! Falling hazard. Stay off the belt when adjusting the tracking. Do not touch or grab the walking belt while it is moving. To adjust the belt tracking: 1. Use the controls on the monitoring system to start the treadmill at minimum speed and grade. 2. Increase speed to 6 mph (9.
Adjustments Rear Roller Guards Check the position of the rear roller guards each time you readjust the belt tracking or the belt tension. The roller guards are located at the rear of the treadmill between the rear roller and the deck (see Figure 4-2). 1 2 Figure 4-2: Roller Guard 1 Adjustment Screws 2 Roller Guard Adjust the guards when the gap between the roller and the guard exceeds 3/8 (0.375) inch (9.5 mm). 1. Disconnect the treadmill power cord from the power source. 2.
Maintenance/Troubleshooting Electrical Testing Electrical testing is to be done by the facility’s biomedical department as required. Check the leakage current of the treadmill periodically—at least every nine months—to be sure it does not exceed local or provincial standards. 4-8 70-00297-01 A TM 55/65 Treadmill 4.
Moving the treadmill Moving the treadmill ! WARNING! Moving the treadmill requires two people. To move the treadmill: 1. Set the treadmill to 3 to 5% grade. 2. To avoid electric shock, turn off the treadmill circuit breaker and the monitoring system, then remove the power cord from the power source. 3. Disconnect all cables that are attached to the treadmill or any other equipment which is attached to the treadmill. ! WARNING! Pinch hazard.
Maintenance/Troubleshooting Storing the Treadmill When storing for prolonged periods, cover the treadmill with a dust cover. Do not store in damp areas. ! WARNING! Falling hazard. Do not store the treadmill on its end as it could fall on someone. Before re-using the treadmill after moving or storage, check the power cord and all attachments to be sure they are undamaged and securely connected, then test the system for proper operation. 4-10 70-00297-01 A TM 55/65 Treadmill 4.
Troubleshooting Troubleshooting If the walking belt does not run, check the monitoring system for an error code. Record the code, if present, then call an authorized technician. If no error message is present, recycle the power by powering the monitoring system off and on again. If this does not eliminate the fault, check the interface cables for proper connection. If problems persist, refer to the Troubleshooting Guide that follows.
