  • Page 27: Routine Maintenance

    • Clean Treadbelt Walking Surface: Vacuum treadbelt to remove loose dirt. If vacuuming does not remove dirt, Landice recommends the use of a medium stiff nylon bristle brush to remove dirt trapped in treadbelt surface. A damp (not wet!) sponge can be used to finish the cleaning process.

  • Page 28: Instructions For Lubricating Treadmills With Slipcoat

    4.3.2. How to Lubricate Note: Only use SlipCoat by Landice. Most standard greases, waxes, and silicone sprays will build up on the rollers and affect belt slippage and tracking and could void the warranty. 1. Before lubricating, loosen treadbelt and slide clean towel under the treadbelt and wipe the deck and under the belt to remove dirt and debris.

  • Page 34 Adjustments Treadbelt Tensioning Figure 5-4. Treadbelt Tensioning Screws To tighten treadbelt, turn both adjustment bolts (clockwise) exactly the same amount to maintain proper tracking. Failure to turn them equally will affect belt tracking. You are moving the take-up roller closer or further away from the deck to tension the treadbelt.

  • Page 35: Treadbelt Tracking

    Treadbelt Tracking Adjustments 5.4. Treadbelt Tracking Treadbelt tracking is maintained by ensuring that the drive and take-up rollers are parallel, each is at right angles to the frame, so that the treadbelt tension from side to side is equal as shown in the following figure. If the treadbelt is running diagonally, with unequal gaps between the treadbelt and sides then the rollers must be adjusted.

In this example, the treadbelt will change tracking as shown by the blue arrow due to the increased tension on the right side and the reduced tension on the left. Readjust if necessary.

    If the motor fails any of these tests, replace it. All Landice drive motors (110 & 220) are direct current (DC). A DC drive motor can generate a DC voltage when it is manually rotated. The DC output is linear to the speed at which the motor is rotated. To perform the Generation Test follow these steps: 1.

  • Page 47: Testing Elevation Motor

    Testing Elevation Motor Troubleshooting • 110 VAC treadmills use a 90 VDC drive motor. For every mile per hour you spin the drive motor you will gener- ate approximately 10 VDC output. So, at 1 mph you will measure 10VDC +/- and at 9mph you will measure 90VDC +/-.

    Troubleshooting Testing Elevation Potentiometer 7. Check for fractured housing or broken motor mounts. Replace if necessary. 6.6. Testing Elevation Potentiometer 1. Remove the elevation pot from elevation motor but do not disconnect the brown, orange and blue wires. 2. Using a digital voltmeter set to ohms (Ω), place probes on the potentiometer prongs with the (orange) and (brown) wires.

  • Page 49: Testing Speed Sensor

    Testing Speed Sensor Troubleshooting 6.8. Testing Speed Sensor The speed sensor is an optical emitter/detector assembly that has its light beam interrupted by a toothed speed wheel affixed to the motor’s shaft. When the speed wheel rotates the teeth interrupt the light emitted by the sensor’s LED and thus creates a pulse train from the detector.
