Interior Depending upon the treadmill environment, dust and or lint can accumulate under the hood. Periodic internal cleaning by an authorized technician is recommended (see Service Manual).
Disinfection If it is necessary to disinfect the treadmill, follow the procedures established by your institution. ♦ 3-2 Maintenance/Troubleshooting
Do not use liquids on the deck surface. Cardiac Stress Treadmills User Guide
Adjustments Tools Required: hex wrenches, Phillips screwdriver Warning!
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. Hold onto the handrail for balance and walk heavily on the treadmill by marching flat-footed. a. If the belt hesitates or lags noticeably, tighten the belt as in steps 3 and 4. Caution!
Do not use all your weight to resist the belt movement. Too much resistance applied too long (more than two seconds) will shut down the system. If this should occur, recycle power to resume normal operation.
b. Increase the speed to 4.5 mph (7.1 km/h) and jog on the treadmill. If the belt hesitates or lags noticeably, tighten the belt as in steps 3 and 4. c. Increase the speed to 6.5 mph (10.3 km/h) and run on the treadmill. If the belt hesitates or lags noticeably, tighten the belt as in steps 3 and 4. 3. Locate the two adjustment bolts at the rear of the treadmill
