BELT ADJUSTMENT

You may need to adjust the running belt during the first few weeks of use. All running belts are properly set 

at the factory. It may stretch or be off-centre after use. Stretching is normal during the break-in period. 

ADJUSTING THE BELT TENSION 

If the running belt feels 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 8MM 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 turn 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 excessive 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 

COUNTER-CLOCKWISE 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-centre. This deflection is normal and the running belt will centre when no body is on the 

running belt. If the running belt remains consistently off-centre, you will need to centre the running belt 

manually. 

A). 

Start the treadmill without anyone on the running belt, press (SPEED UP) bottom until speed reached 

6kph. 

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.
