Your unit has likely one of 2 problems. It most likely needs a new motor belt installed. The micro V belt can be ordered from ICON for about $20. The other possibility is the walking belt tension is too loose. Lift up the edge of the walking belt firmly in the middle and you should be 2-3 inches above the walking board. Don't overtighten the rear roller screws to increase the tension beacause it will make the motor work harder and if it is a worn motor belt, the extra tightening won't make much of a difference.

B) Walking Belt/Motor Belt too Tight:

If you have adjusted the walking belt or motor belt recently, check for this problem. When the belts start slipping, some people just crank

down the belts and on treadmills, tighter is not necessarily better. The tighter the belts, the more the drive system has to work to keep

everything moving. You should be able to lift the walking belt (with the treadmill unplugged) in the center of the treadmill about 3" without

straining. Tighter belts should be loosen but make sure you don't create a dangerous slipping situation by loosening.

The motor belt (with the treadmill unplugged) should be able to be turned by hand to almost a 90 degree angle from its normal operating

position. Loosen the belt if too tight. Make sure to test for slipping

and if it does with the proper tension, replace the motor belt.

I have a life fitness t5 and live in the middle of nowhere in new Mexico. I run at 6.5 mph for 40 minutes around 5 times a week. I have used it for approx 1 year. It is impossible to get reliable...

Dear Sir:

I will indicate some Tips for maintenance:

Any equipment is difficult to survie without a properly maintenance.

But you can do something very simple.
Cleaning Dirt and debris is a major cause of premature belt and deck wear. Clean between the belt and the deck once per week. Also clean the small exposed areas of the deck on each side of the belt. Dirt tends to accumulate in these areas. Wipe down the entire treadmill once per week. The outside surface of the belt can be cleaned with a damp sponge or cloth. Vacuum or wipe up the area around your treadmill at the same time. You should clean the motor area three or four times per year. Unplug the treadmill before removing the cover. Follow the instructions in your owner's manual for removing the cover. Carefully vacuum the dust and debris from around the motor.2)
Lubrication Read and follow your owner's manual for lubrication recommendations. Some treadmills do not require lubrication. In fact, unnecessary lubrication can cause damage. Many decks are made of materials that do not require lubrication or are pre-impregnated with wax. Lubricating these types of decks can actually increase the friction between the belt and deck, which can lead to motor damage. If your treadmill does require lubrication or waxing, follow the manufacturers guidelines.
Belt Tension Belt tension is pre-adjusted at the factory, however, new belts will stretch and require readjustment. If the belt is too loose, it will slip and cause excessive wear to both the belt and the deck. If the belt is too tight, it will cause wear to the rollers and to the motor. The belt should be set just tight enough so that is does not slip. With the belt running slowly, stomp your foot forcefully down and slightly forward on the belt. If you feel the belt slip, tighten both bolts 1/4 turn. Again, follow your manual for instructions specific to your make and model.
Belt Wear There are two components in your treadmill, which will require periodic replacement - the belt and the deck. Check the condition of your belt every three months. Feel the underside of the belt. If it feels rough and worn, it may be time for a new belt. Continuing to run on a worn out belt will increase the wear on the deck. The deck will eventually wear out also, but if you replace your belt when necessary, you will increase the life of your deck
I hope this will be keep your safe with your equipment.

When I run on my 620 it feels like it slips and I almost fall, like I'm running in my socks on a tile floor. This just started happening and now I can't use it at all, is there something I can tighten?

You mean front- to-back or side- to-side?

If its side to side, adjust the allen bolts at the bottom front of the treadmill. If its front to back, and your treadmill is at least a few years old, the belt is probably stretched and needs replacing. You can get a quote for a new belt at

When i start running it isnt a steady flow of the belt there is jerks every few seconds making it very hard to run and almost is enough to make you fall what do you think the problem might be

It sounds like you either have a loose walk belt or a slipping front drive pully. The walk belt shoould be tightened so that you can pull up on the edge of the belt about 2 inches. If that is OK, pull the motor cover, start the treadmill and walk trying to stop the belt with you feet. Watch the drive belt this time (the small one going from the drive motor to the front drive roller), if this belt stops, you need to tighten motor, or replace if it is older/wornout. If the drive belt keeps turning fine, watch the front roller and see if the pully connected to the drive belt keeps turning while the roller connected to the walk belt stops, if so you need a new front drive roller.

Hope this helps

The treadmill belt is making a noise and feel like it hesitates for a second while I am walking.

If it has a low pitch growling when you start unit then the running belt is too tight and the adjusting bolts need to be backed until the growling noise is lessened or eliminate without the running belt slipping.
If it is the drive belt slipping, the adjustment bolt is underneath the frame so you will need to elevate the treadmill and adjust the bolt until slippage is eliminated without over tightening the drive belt.

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

How do I adjust tension on walking belt

A good way to test your walk belt to see if it is slipping is to stand on side rails with treadmill running about 4mph and while holding onto handrails keep one foot on the side rail and put your one foot on the center of the belt in a slight stomping motion,if the belt is loose you will feel it slip. To adjust a loose belt tighten each screw at back of treadmill 1/2 tun each until the slippage goes away. Be sure not to over tighten belt as this will cause excessive wear.If the belt has shifted to one side and you need to center it, go to the side it has shifted to and turn the screw clockwise 1/4 turn at a time until it centers.
