Electro help: SPORTSART - T680 - TREADMILL WALK BELT ADJUSTMENT

WALK BELT ADJUSTMENT IS NEEDED, WHEN THE BELT TRACKS TOO MUCH TO ONCE SIDE, OR WHEN THE BELT IS TOO LOOSE OR TIGHT.

To increase or decrease walk belt tightness, turn adjustment screws on both sides. Turning adjustment screws clockwise pulls the belt tighter. Turning counterclockwise makes the belt looser. Tip: To maintain tracking when tightening or loosening a walk belt, simultaneously turn adjustment screws on both sides an equal amount.

The walk belt should rotate in the center of the deck with equal space on both sides. To adjust a walk belt that tracks improperly to one side, turn one adjustment screw. Example: If the walk belt tracks to the right side, turn the right adjustment screw clockwise. This adjusts the right side of the rear roller toward the back, pushing the walk belt to the left side. Likewise, turning the left adjustment screw clockwise would make the walk belt move toward the right side.

Set speed to 4 KPH/2.5 MPH.

If belt tends to one side, adjust one side only until the margin [A&B] on both side is the same.

Test belt tightness by lightly bearing against it.

If too loose, turn adjustment screws on both sides equally one half to one turn. If too tight, turn adjustment screws on both sides counterclockwise one half to one turn.

When you test belt tightness, if the motor operates normally,

But the walk belt can be stopped for more than ½ second, the walk belt is too loose. Simultaneously rotate both adjustment screws clockwise 1/2 to one turn. Test again. Adjust until the walk belt slips briefly but quickly regains traction and begins to rotate.
And the walk belt cannot be stopped or slowed whatsoever, the belt may be too tight. Simultaneously rotate adjustment screws counterclockwise 1/2 to one turn. Test again.

Adjustment Circumstances

The walk belt is crooked or too far to one side.
