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
