Why does the belt keep veering left?

A belt is known to stretch and begin to slip after a certain amount of time/Also depending on use.

Try adjusting your treadmill belt, there should be two bolts on the right and left rear side of your machine.

Make sure to keep track of how many turns you give to each side, since you are tightening your belt you will be turning the bolts clockwise. Making equal turns on both sides.

After each adjustment, check the belt by pulling up on the belt from the center, you should not have too much space between the deck and the under side of the belt.

Once you feel the belt is tight enough, run the machine at a low speed.
Check to see that the belt is not veering off too much to one side, if it is moving over too much to one side this can cause fraying and damage to the belt.

Certain treadmill models have a safety feature that stop the machine when they know something is wrong, it could be that there is a problem with your main control board (Circuit Board).

You can remove the main shroud, and verify that the circuit boards LED's are on and that there are not any visually burnt or damaged components. If there are any, that could be a good indication of something being wrong with the board.

Mine has an adjustment setting on the rear as well and I lined mine up using the rear setting.

Tighten the LHS only. It runs to the LHS because the RHS has been tightened more. Try turning 180 deg clockwise on the LHS with the machine running @ 2 kph. The machine must be running to adjust.Turn 45 deg at a time if the first 180 wasn't enough.

hai ,
pls check 12pin communication cable and speed sensor wire also

hi, check the 12pin communication cable

Take the end caps and motor shroud off visually inspect the frame tension bolts to see if anything is bent. then loosen, ( count how rotation it took to loosen the so when tighten the belt up you won't have to guest at the tension ) the belt and edges of the belt to see if the weave is uneven this cause the belt to travel. If you can tip the treadmill on its side to inspect underneath to see if anything skewed. Take your time and observe the mechanical operation you may have the above a 1/2 a dozen time before you see the problem, other than that anything short of replacing the belt this my recommendation. Good Luck to you

If the walking belt is off-center, first remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left idler roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise 1/2 of a turn. Be careful not to overtighten the walking belt. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes.

there should be adjustment screws on the rear roller.
only adjust one of them (usually the left) if the belt rubs on the left turn the screw clockwise 1/4 turn and if the belt rubs on the right turn counterclockwise. Make small adjustments until the belt stays in the center

please look under the bottom of the treadmill and be sure that your alignment brackets are not benmt/missing. (put the machine in the storage position and look about 2/3 way down the side of the belt) you should see a metal bracket on each side pressing in on the belt. They should be pressing in about 1 1/2 -2 inches to help track the belt.

The rollers in the front and rear need to be adjusted. If its sliding to the left, than the left side needs to be adjusted out until the belt stops going that way and stays on straight.
