Service manual TREADMILL ERGOMETERS 0344 Intended Use A Lode treadmill is a diagnostic tool intended to be used as a stress test device in a medical environment. The main goal of the use of a Lode treadmill is to create reproducible stress tests. The following parameters can be measured: • Speed (km/h or Miles/h) • Time (minutes and seconds) • Distance (km Miles Meters) • Optional: Heart rate (beats per minute) • Grade (%) In combination with other diagnostic tools, like ECG or pulmonary function equipment, other important physiological data can be obtained, allowing a physician to evaluate a test subject’s physical status. A Lode treadmill is designed both for manual operation and control by external ECG-, pulmonary equipment. In combination with optional software, the ergometer can also be controlled by a PC. The Lode treadmill has to be operated under the supervision of well-trained medical specialists, like cardiologists, pulmonologists and physiotherapists. The ultimate judgment whether a test subject should undertake a stress test with an ergometer and which protocols should be used must be made by the responsible medical specialist, based on the limitations of each individual, the medical history and all other applicable circumstances. Neither Lode BV nor her distributors take any responsibility for the final use of its equipment. Contra Indication The Lode treadmills are to be operated by classified personnel only.

Fig.1: Location Grade potentiometer Fig.2: Bottom side treadmill If, for some reason, the grade potentiometer is broken, the treadmill could be in a specific angle. To change the potentiometer, the best position would be the 25 % angle. Sometimes the treadmill doesn’t allow you to set the angle to 25 % because of the defective potentiometer. e.g. “STOP” will be displayed. In this case you should lift the rear end of the treadmill (the opposite side of where the motor is located.) Place this end on a stable frame so you have space to work under the treadmill. Fig 3: Lift backside of the treadmill WARNING Remove the power cable from the treadmill before you start working on the treadmill. Remove the allen screw which holds the potentiometer in position. Desolder the wires from the potentiometer. Heat the gear wheel at the axle of the potentiometer and slide it off without damaging it. Remove the screw which holds the potentiometer in the metal plate. Put the new potentiometer, 10-turns 10K, into the metal plate and fasten it with the screw. Place the gear wheel on the axle again buy using Loctide # 638. Service manual Valiant treadmill V1.00 24 Resolder the wires onto the potentiometer. Fig. 4: Wiring the potentiometer. Now you have to open the front cover of the treadmill, by removing the white housing. See service manual appendix B. When the white housing of the motor compartment has been removed connect a DC voltmeter to pin 2 ( U-elevation) and 3(GND) of connector 5. The DC meter should be in the range from 0-20 volt. Fig.5: Connector 5, Power supply board. Fig.6: Enlarged If the treadmill is not is the highest position, set U-elevation by turning the potentiometer at 0,5 Volt and press the “arrow up” key till the grade indicates 25%. The treadmill should elevate to 25%. At the display you will see the set angle and the actual angle. The actual angle at the display of the control unit will remain 2-3% (because the potentiometer is not mounted in the treadmill.) When the treadmill has reached 25% you can turn the potentiometer till U-elevation has reached 4.30 Volt ± 0.05 Volt. Read the Voltage from your DC Voltmeter. Now switch off the treadmill and place the potentiometer with the gear back in position. Service manual Valiant treadmill V1.00 25 Fig.7 & 8: Potentiometer gear positioning When you switch on the Valiant the treadmill should first go to the lowest position.

The grade should be within 1%, If the grade of the Valiant is not within specifications, check if the grade motor and grade potentiometer are working properly and make sure there is no obstruction in its way up or down. You can use an angle measurement tool to measure the grade of the Valiant. Service manual Valiant treadmill V1.00 46 But it can also be done as follows: - You can measure the height at a certain point (o) - After that you can measure the length (a) on the floor. - The grade can be calculated as follows: Service manual Valiant treadmill V1.00 47 6.4 Walking belt tension The walking belt can be tightened by means of the two outmost socket screws placed on the feed at the end of the frame: First decrease the tension on the walking belt fully by turning both tightener socket screws anti-clockwise. To prevent from unnecessary disturbance of the walking belt alignment the number of turns should be kept equal on both socket screws. The walking belt tension can be adjusted according to procedure 1 or 2: 1. When the walking belt is quit slack, start the walking belt at minimum speed. Turn both tightener socket screws an equal number of turns clockwise until the walking belt, when it is slowed down with your feet, just stops slipping on the driven roller. Then give both tightener socket screws 2.5 additional turns. 2. When the walking belt is quit slack, put two marks (on adhesive tape) in the middle of the walking belt with 1000 mm. distance between them. Turn both tightener socket screws an equal number of turns clockwise until the distance between the two marks is 1003 mm (the walking belt is stretched 3 mm. over a length of 1000 mm.). After each adjustment of the walking belt tension the alignment of the belt should be checked. Caution: Do not tighten the belt to much. This will shorten the service life of the walking belt and it will make the drive motor run unnecessary heavy. Service manual Valiant treadmill V1.00 48 6.5 Walking belt alignment The alignment of the walking belt is correct when the belt runs in the middle of the supporting plate. The walking belt alignment can be adjusted by means of the socket screw located at the left side of foot at the end from the frame. Set for a speed of approx. 10 km/h; the walking belt will react faster to adjustments made at a high speed. To adjust the walking belt alignment, use the left socket screw. To make the belt move to the left side, turn the socket screw anti-clockwise. When the walking belt moves too much towards to the left side, turn the same socket screw clockwise (see figure). Make sure to use only the left socket screw to adjust the walking belt tension, using both socket screws could result in a high walking belt tension. This will shorten the service life of the walking belt and it will make the drive motor run unnecessary heavy. The figure above shows the Valiant from the rear side. Service manual Valiant treadmill V1.00 49 6.6 Motor belt tension The tension of the motor belt can be checked by pulling the belt up and down in the middle between both pulleys. The full stroke must be about 10 mm. To change the tension of the belt remove the locking nut on the spanner socket screw of the motor belt. Turning the adjustment nut on the spanner socket screw will tilt the motor upwards (increase tension), or downwards (decrease tension). Caution: Do not over tighten the belt. This will shorten the service life of the motor belt and it will make the drive motor run unnecessary heavy. Service manual Valiant treadmill V1.00 50 6.7 Inclination system Remove the cover of the motor drive unit. Loosen the socket screw of the mounting bracket of the elevation feedback potentiometer. Turn the gear wheel of the potentiometer away from the driven gear wheel. Switch on the main supply, the inclination system will move to the lowest position and you must switch the main power supply OFF BEFORE the wheels contact the housing. Turn the potentiometer fully clockwise (seen from the left side of the Valiant). Turn the bracket back to the position where both gear wheels connect. Turn the gear wheel of the potentiometer half round anti-clockwise, without moving the driven gear wheel, before fastening. After adjustment of the potentiometer a functional test of the inclination system should be carried out. Caution: There must be some tolerance between the gear wheel of the potentiometer and the gear wheel of the elevation unit. This is to avoid damage of the potentiometer. Inclination system lubrication The gearing wheels and spindle should be lubricated annually with white grease. Service manual Valiant treadmill V1.00 51 ">
