Lose speed the treadmill

There could be a few possible reasons for your Trojan Runx treadmill to have this issue:

1. Belt tension: The treadmill belt may not be tight enough, causing it to slip and lose speed. You can adjust the belt tension by using an Allen wrench to tighten the bolts at the back of the treadmill.
2. Motor: The motor may be overheating and shutting off, causing the treadmill to slow down. You can check the motor by opening up the motor cover and looking for any signs of burning or overheating.
3. Motor brushes: The motor brushes may be worn out and need replacing. This can cause the motor to run slower and eventually shut off.
4. Power supply: The power supply to the treadmill may be insufficient, causing it to lose speed. Make sure the treadmill is plugged into a dedicated circuit and not sharing power with other appliances.

If you're unsure about how to diagnose or fix any of these issues, it's recommended to contact a qualified technician or the manufacturer for assistance.

Be sure to verify if you are getting the noise while you are physically on the machine or with no one on it
Creaking or squeaking while running on the machine usually indicates an issue in your incline motor, deck frame, springs, and or pivot points

A loud grumbling noise getting louder and louder while elevating speed, usually means you have a bad bearing

Any knocking noise coming from a treadmill indicates bad bearings in your front roller, rear roller, or drive motor

Isolate the bearings in the front and rear rollers from the drive motor bearings

To test: Unplug machine, remove the main shroud, remove drive belt from drive motor and front roller pulley

After doing so, move the treadmill belt by itself by pushing it backward or forward with just your hands and listen for any noise, if you get any noise it is most likely coming from either the front or rear roller. To isolate the noise out of the two rollers you must remove the rollers and turn each one individually.

If no noise with the first test, go ahead and start the machine and run it at a low speed. You want to listen for noise, if you get knocking or grumbling while drive motor is running with no drive belt attached then the issue is in your Drive Motor.

A lot of times simple maintenance will save your treadmill from noise, you want to make sure and lubricate your treadmills *pivot points. Incline motor bolt, shaft, deck screws, and or any *pivot points on the bottom of your machine. Metal on metal *pivot points are usually the culprit in most cases.

*Pivot points are just areas of high friction where there may be a bolt, washer, and nut attached to the base of your frame or any hinges on your folding type treadmills. Metal to metal needs to be lubricated to minimize wear and tear of those areas.

Synthetic grease works best or any spray on lubrication works fine if you do not want to remove any bolts or hardware.
