Belt moving over to one side

There are two holes on each side of the back covers of the treadmill. They have the adjustment bolts in them for the rear roller and It will require an Allen wrench to adjust it. If you tighten one of the bolts it causes the belt to move away from that side. So if it's the left side of the belt that's moving close to the rail then tighten the left side and vise versa for right. Turn the unit on and set the speed to about 3. Tighten the side that the belt closer to the side rail about a quarter turn. Be patient and give it a minute to settle after you adjust it. Repeat until the belt has moved back to center. If it moves too far just back it off a bit.

Hey Joe, at the back of the treadmill, you have the rear roller. The roller has a tension screw in both sides that are the adjusters as well. As you tighten the right side it will force the belt to the left, and vice versa. I turn the walk belt on to speed two, be carefull the belt will be moving. Slowly adjust one side and watch the belt move, then the other side until it centers. Shut it off, the belt should lift from the middle no more than two inches with a firm lifting force. That's it. You might need to tweek it to keep it centered.

Hope this helps, Matt

First, check the level of your power steering fluid and top up the level if low. Then adjust your serpentine belts. A loose belt may be causing the the steering wheel. To adjust your alternator belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp. Facing the back of the car, reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change or adjust the belt.
To take off or adjust the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the adjuster pulley (right side ,belt is on the left) . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley forward and backward to adjust the steering pump belt tension

BEFORE ADJUSTING THE ALTERNATOR BELT DISCONNECT THE NEGATIVE BATTERY CABLE OR YOU MIGHT BLOW AN EXPENSIVE HIDDEN FUSE.
I would replace the steering pump belt at the same time you do the alternator belt (buy both).

When you purchased the treadmill it came with an allen wrench to assemble the machine. That is the adjustment tool.
Inspect the rear plastic cap (the adjustment bolts are there) make sure it is not damaged. If the plastic is broken, it will need to be replaced. This job is not easy. If it is not broken, adjust the belt as follows..
If the belt is already rubbing, locate the adjustment screw at the back of the treadmill on the side that is rubbing.Adjust that screw tuning it 1/2 turn clockwise. Move the belt manually 3 full rotations.. If it is still rubbing, turn another 1/4 turn. Again move the belt manually 3 rotations. Once the rubbing stops, run the machine slowly and watch the belt from the back of the machine..

Tighten the rear adjusting bolts until the walk belt it tight enough to lift about 1.5 inches at the sides of the walk belt. After you do this, Turn the treadmill on to speed setting 2, and be ready to tighten the side that the belt is closest to.( if the belt is against one side, start with that side) Tighten only 1/2 a turn at a time and watch the belt start to move. It wont take much once it starts to move. Only tighten each side ( if necessary) dont loosen the bolts. Once the belt is in the middle, leave it alone. The belt is now adjusted. You may see it travel to one side, breifly, but it will return on its own.

The walking belt may be too loose. If you have made recent adjustments, lubricated, or had repairs, a belt can slip if not tightened. The belt can slip if you have too much friction or if the belt has been recently lubricated. If lube does not help your problem and you have exhausted all other possibilities, the walking belt is most likely worn out and must be replaced.
To adjust the belt: Less Belt Tension: turn both adjustment bolts on back of treadmill in a counter-clockwise direction. More Belt Tension: Turn both adjustment bolts equally in a clockwise direction. Center Adjustment (moves belt center to the left): Turn left-side adjustment bolt counter-clockwise. Center Adjustment (moves belt center to the right): Turn the left-side adjustment bolt clockwise.
An over tightened walking belt can raise the amp draw of your treadmill, contribute to seam separation on the walking belt, or both, so do not over tighten the walking belt.
You should be able to lift the belt in the center on the side by approximately 2” to 3”, if you cannot lift it by 2” to 3”, the belt is too tight.
