LEFT 

ADJUSTMENT

When adjusted properly, the 

Avari® Adjustable Height Treadmill’s

WALKING BELT(11)

 will roll smoothly 

around the 

BOARD(10)

 and over the front and rear rollers without catching or rubbing. For the belt to run 

smoothly, there are a few points that need to be noted

.

BELT ALIGNMENT

The 

WALKING BELT(11)

 must be in the center of the 

BOARD(10)

 to prevent it from rubbing against the 

FLYWHEEL COVER(9).

 If the belt rubs the 

FLYWHEEL COVER(9),

 it will be difficult to keep the belt moving 

and will eventually damage the edge of the belt. The treadmill has belt guides welded to the bottom of the 

treadmill frame that move the belt toward the center of the treadmill. However, the 

REAR ROLLER(8)

 must 

be properly aligned with the treadmill frame and 

FRONT ROLLER w/FLYWHEELS(7)

 if the belt is to remain 

centered on the treadmill. The bolts in the rear of the treadmill (one on the left and the other on the right) 

adjust the alignment of the 

REAR ROLLER(8)

 as well as the tension of the belt

The belt will run to the side of the loose rear bolt.

Hint: 

Visually check the 

REAR ROLLER(8)

 to make sure both the right side and the left side of the 

REAR 

ROLLER(8)

 are the same distance from the back edge of the treadmill. Using the 5mm 

ALLEN 

WRENCH

, make adjustments by turning the bolts clockwise to tighten and counterclockwise to loosen. 

BELT DRIFTING LEFT

Adjust by turning the left screw 1/4 turn CLOCKWISE and the right screw 

1/4 turn COUNTERCLOCKWISE. Walk on the treadmill to check alignment. 

Repeat if needed.

BELT DRIFTING RIGHT

Adjust by turning the left screw 1/4 turn COUNTERCLOCKWISE and the 

right screw 1/4 turn CLOCKWISE. Walk on the treadmill to check alignment. 

Repeat if needed.

NOTE:

When you believe the 

WALKING BELT(11)

 is centered, use the treadmill for three (3) minutes to verify the 

WALKING BELT(11)

 won’t drift to one side or the other. If the 

WALKING BELT(11)

 continues to drift, the 

floor may not be level. Rotate the treadmill 90 degrees or move the treadmill to another location.

BELT TENSION

The 

WALKING BELT(11)

 should be taut and not lying loosely on the treadmill 

BOARD(10).

 If the belt is 

too loose, it will slip on the front roller and you will notice a jerky movement when you walk on the treadmill. 

If the belt is too tight, the edges of the belt will begin to curl and more effort will be required to move the 

belt. Excessive belt tension can also damage the bearings in the rollers. The bolts on the ends of the 

MAIN 

FRAME(1)

 (one on the left and the other on the right) adjust the 

WALKING BELT(10)

 tension as well as 

the 

REAR ROLLER(8)

 alignment.

BELT TOO LOOSE:

  Use  the  5mm 

ALLEN WRENCH

 to tighten the bolts on the ends of the 

MAIN 

FRAME(1).

 Tighten both bolts 1/4 turn clockwise at a time until the belt stops slipping on the 

FRONT 

ROLLER w/FLYWHEELS(7).

BELT TOO TIGHT

:

 Use the 5mm 

ALLEN WRENCH

 to loosen the bolts on the ends of the 

MAIN FRAME(1). 

Loosen both bolts 1/2 turn counterclockwise at a time until the belt begins to slip on the 

FRONT ROLLER 

w/FLYWHEELS(7).

 Then use the procedure above to tighten the belt to the proper tension.
