    CONTENTS THE FOOTFALLS/HISTOGRAM SCREEN (See Figure 4.4 – 4.5.) Figures 4.4. and 4.5. Patients can view the Footfalls/Histogram screen with either Footfalls or Histograms displayed. In the Footfalls screen, the solid foot marks the user's last foot placement while the box is a target for the next foot placement.
  • Page 13 CONTENTS • Speed (Cycles/Second): Located at the top right of the screen. Use the associated L and M icons to set this goal to match the desired cycles per second. The step cycle default is 0.10 cycles/sec and the range is 0.1 to 5 cycles/sec. This parameter, in conjunction with the patient’s height, is used to determine belt speed (since walking speed is determined by step length and step cycle) and is important for developing proper gait patterns.

  • Page 35: Maintenance

    QUARTERLY MAINTENANCE Lubricate Treadbelt and Slider Deck The Biodex Lubricant Kit is designed to reduce friction between the treadbelt and the slider deck. It is required for all institutional treadmills. Proper and timely application of the lubricant will prevent premature failures due to excessive wear and load. Items affected by inadequate lubrica- tion are the treadbelt, slider deck, motor, and motor controller.

  • Page 36: Maintenance Procedures

    Allow the Gait Trainer to dry for approximately 10 minutes. NOTE: Use only the Biodex lubricant kit with your Gait Trainer. Most standard greases, waxes and silicon sprays will build up on the rollers, causing belt slippage and affecting tracking.
  • Page 37 CONTENTS Remove the two aluminum traction strips, located one on each side of running deck. These are secured by four Allen screws located on top of traction strips. Remove rear treadbelt roller. The roller is secured by two treadbelt tensioning bolts. Once bolts have been removed, lift out the roller assembly.
  • Page 38 CONTENTS Tracking Tracking adjustment is necessary when a pronounced bump appears toward the left side of the belt, approximately two inches from the left edge. This occurs when the belt works its way out of the Exact-Track grooves. To Adjust Treadbelt Tracking: Tighten the hex tensioning bolt on the side to which the treadbelt has migrated, turn bolt in 1/8 increments clockwise.
