When a running belt has excessive wear, it creates a lot of friction which causes the drive motor to work harder. When the drive motor works harder it will start overheating. If the belt is not lubricated periodically, it will ruin the deck, the drive motor, and cause other electrical problems such as tripping the breaker [after a while, the circuit breaker on the treadmill will need to be replaced.
It is suggested to lubricate the belt every month. At this point, you may need to replace both your deck and your running belt.

Hi
not to sound funny but are you sure that you have this tread set in the units (mpg/kph) that you require. i have worked in loads of gyms and its a common problem that people think the belt is running to fast because its set in kph and that thinks its in miles eg 9mph = 14.5kph
you can check and change the units in the club setting menu.
hope this helps :)

SOURCE: The belt of my treadmill

Hi stewarvm,

you either have a loose belt or possibly a bad bearing.

grab each roller (front and back of treadmill) and try and shake it up and down and front to back to
to make sure the bearings are ok...if they move a lot, then you probably have a bad bearing...if theres no movement, or very litte, they should be ok

now make sure the belts ok by looking at it and determining if one side is looser then the other (the right side should appear or feel looser) then tighten the right adjusting bolt till the belt tracks in the center. the adjuster is at the rear, one on each side of the rear roller.

HERE is a video and instructions of how to track your belt.

its pretty easy to fix and should only take a few minutes to get it right with a little trial an error if you never did it before.

let me know if you need further help.

The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.


Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Cuts off and speed is variable and shows err 4


Precor Error E4, Incomplete Initialization Probable Cause Indicates that an incomplete upper PCA to lower PCA initialization occurred. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Run the initialization program. Caution: The treadmill's running belt will accelerate to the treadmill's maximum speed (12mph). DO NOT stand on the treadmill's running belt during the procedure.
  1. Set the on/off switch to the OFF position. Wait a minimum of 10 seconds to allow the internal power supply to discharge.
  2. Remove the safety key from the console and set the on/off switch to the ON position.
  3. Press INCLINE UP and SPEED DOWN keys together. While pressing these keys, replace the safety switch on the console. Continue holding the INCLINE UP and SPEED DOWN keys until the display goes blank. INIT will appear in the time window of the display. The EEPROM is now clear and reset. After a second, 1.25 will appear in the distance/calories window, 15.0 (the maximum incline) will appear in the incline window, and 12.0 (the maximum speed) will flash in the speed/pace window.
  4. Press QUICKSTART to begin the speed calibration process. Power bits will appear in the incline window, the target speed will appear in the time window and the actual speed will appear in the speed/pace window. At the beginning of the process, the target speed will be .5mph. The running belt will start. Once the actual speed reaches .5mph, the target speed will then change to 12mph and the running belt will accelerate until it reaches 12mph, then it will stop.
  5. When the running belt stops, the display will return to the user mode and the initialization process is complete.

I currently replaced the walking belt on my C954i/C956i treadmill. When I plugged it back in and turned on the power, the treadmill has no power. What could have happened?


Dear Sir:
I can read you trouble, and follow the next steps:
ALIGNING AND ADJUSTING THE RUNNING BELT
The correct alignment of the running belt is critical to the smooth operation of the treadmill. The belt is properly aligned at the factory. However, during shipping and handling or by use on an uneven surface, the belt may move off center and require a few simple adjustments. Before aligning the running belt, check its operation by following the procedure in Checking the Alignment of the Running Belt. If you determine that the belt needs alignment, follow the instructions here. CAUTION: Special care must be taken when aligning the running belt. Turn OFF the treadmill while adjusting or working near the rear roller. Remove any loose clothing and tie back your hair. Be very careful to keep your finger or any other object clear of the belt and rollers, especially in front of the roller and behind the deck. The treadmill will not stop immediately if an object becomes caught in the belt or rollers. Realigning the belt takes a few simple adjustments. If you are unsure about this procedure, call Precor Customer Support (see Obtaining Service.) Take the following steps to align the running belt on the treadmill. To ensure your safety, make all adjustments while the treadmill is OFF. 1. Make sure the treadmill is OFF and the running belt has completely stopped. 2. Locate the right belt adjustment bolt in the rear end cap of the treadmill. (To determine left and right, stand at the rear of the treadmill and face the display.) See Diagram 24. The direction you turn the bolt depends on how the belt is tracking. Make all belt adjustments on the right rear corner bolt using the hex key provided. • If the belt is off center to the RIGHT, turn the adjusting bolt ¼ turn clockwise, which moves the running belt to the left. • If the belt tracks off center to the LEFT, turn the bolt ¼ turn counterclockwise; this moves the belt to the right. Important: Do not turn the adjusting bolt more than ¼ turn at a time. Overtightening the bolt can damage the treadmill. 3. Turn the unit ON. 4. Stand beside the treadmill and press QUICKSTART. 5. If you are prompted for a password, press INCLINE ??¼, SPEED ??¼, SPEED ??². The running belt starts automatically after the 3-second countdown appears on the display. 6. Press the SPEED ??² key until the display shows a speed of 3 mph (5 kph). 7. Walk around to the rear of the unit and observe the running belt for a few minutes. The belt should run centered along the running bed. If the belt drifts off center, you will need to make adjustments. CAUTION: If you hear any chafing or the running belt appears to be getting damaged, stop the running belt immediately by pressing the red STOP button. Contact Precor Customer Support. 8. If the belt needs additional alignment, repeat steps 1 through 7 until the belt is properly aligned. 9. After aligning the belt, press the STOP button and RESET. Turn OFF the treadmill. Tighten any loose fasteners or other components on the equipment. If you hear unusual noises or you feel that the treadmill is in need of repair or service, contact Precor Customer Support. Refer to Obtaining Service.
Finally, check if the power cord is loose, connect it again. a) See if the breaker of Home is tripped? b) See if the breaker of the Treadmill is tripped. If do the Belt is very Tighted! loose a little. Try again.
Thank you in advance, if you need assistance, you can contact me, Blessing. sincerely.

After walking for 10 minutes or so, or even sooner when I am jogging, the 921 loses power and trip my house circuit breaker. What needs to be replaced? Guessing it is the power cord as the 921 is 20...


Check your Amps on the circuit that is being tripped. The treadmill needs 15 Amps to run. If you have a 15 Amp circuit that is running the treadmill and other electronics (or lights), the circuit will trip. You may need to replace the circuit with more Amps.
