BELT ADJUSTMENT
BELT ADJUSTMENT
You may need to adjust the running belt during the first weeks of use. All running belts are properly
set at the factory. It may stretch or be off-center after use. Stretching is normal during the break-in
period.
ADJUSTING THE BELT TENSION
If the running belt feel as though it is "slipping" or hesitating when you plant your foot during a run,
the tension on the running belt may have to be increased.
TO INCREASE THE RUNNING BELT TENSION
A) Place 6mm wrench on the left belt tension bolt. Turn the wrench clockwise 1/4 turn to draw the rear roller and
increase the belt tension.
B) Repeat STEP "A" for the right belt tension bolt. You must be sure to run both bolts the same number of turns, so
the rear roller will stay square relative to the frame.
C)
Repeat STEP "A" and STEP "B" until the slipping is eliminated.
D)
Be careful not to tighten the running belt tension too much as you can create excessively pressure on the front
and rear roller bearings. An excessively tightened running belt may damage the roller bearings that would result
in bearing noise from the front and rear rollers.
TO DECREASE THE TENSION ON THE RUNNING BELT, TURN BOTH BOLTS COUNTERCLOCKWISE THE SAME
NUMBER OF TURNS.
CENTERING THE RUNNING BELT
When you run, you may push off harder with one foot than with another. The severity of the deflection depends on the
amount of force that one foot exerts in the relation to the other. This deflection can cause the belt to move off-center. This
deflection is normal and the running belt will balanced or no body is on the running belt. If the running belt remains
consistently off-center, you will need to center the running belt manually.
A) Start the treadmill without anyone on the running belt, press (SPEED UP) button until speed reached 6 kph.
B)
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 wrench, turn the left adjustment bolt clockwise 1/4 turn and the right adjustment bolt
counterclockwise 1/4.
b.
If toward the right side of the deck:
Using wrench, turn the right adjustment bolt clockwise 1/4 turn and the left adjustment bolt
counterclockwise 1/4.
c.
If the belt is still not centered, repeats the above steps until the running belt is on center.
C)
After the belt is centered, increase the speed to 16kph 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.
