OPTi 604/6848 - Centering the Running Belt

When you run, you may push off harder with one foot than with the other. The severity of the deflection
depends on the amount of force that one foot exerts in relation to the other. This deflection can cause the belt
to move off-centre. This deflection is normal and the running belt will centre when nobody is on the running
belt. If the running belt remains consistently off-centre, you will need to centre the running belt manually.
Care and Maintenance
Centering the Running Belt
1. Start the treadmill without anyone on the running belt, press “Speed+” button until speed reaches
6Km/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 will find its new position; if it’s still moving toward left side, turn the bolt
further for 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 center, repeat the above steps until the running belt is centered.
3. After the belt is centered, increase the speed to 12km/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,
you may need to increase the belt tension.
