CENTERING THE RUNNING BELT
MOTER BELT TENSION ADJUSTMENT
17
During your workout, if you find the running belt is not running smoothly, it could mean that the motor belt
has lost some tension, please follow the below steps to adjust the motor belt tension:
1.
Turn the motor belt adjustment bolt using an M8 Allen wrench 1/4 turn in clockwise direction.
2.
Re-Start the treadmill and run on the treadmill; if the running belt is still not working properly, repeat
above step.
3.
Please do not make the motor belt too tight; if the belt is over tightened, it will cause the treadmill over
loading and reduce the motor life.
1.
Start the treadmill without anyone on the running belt, press “Speed+” button until speed reaches
4mile/h.
2.
Observe whether the running belt is toward the right or left side of the deck.
a) If toward the left side of the deck, using 6# Allen Wrench, turn the left adjustment bolt
clockwise 1/4 turn and let the running
belt find its new position;
if it’s still moving toward left side,
turn the bolt another 1/4 turn.
b) If toward the right side of the deck, using 6# Allen Wrench, turn the right adjustment bolt
clockwise 1/4 turn and let the running belt will find its new position;
if it’s still moving toward right
side, turn the bolt further for 1/4 turn.
c) If the belt is still not centered, repeat the above steps until the running belt is centered.
3.
After the belt is centered, increase the speed to 8mile/h and verify that it is running smoothly.
Repeat the above steps if it is necessary. If the above procedure is unsuccessful in resolving the
off-center issue, you may need to increase the belt tension.
