Proper Grounding

LifeSpan equipment must be grounded. Improper connection of the equipment’s grounding conductor can result in the risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product or use a ground plug adapter to adapt to a non-grounded outlet. If the plug will not fit in the outlet, have the proper outlet installed by a qualified electrician.

Power Cord Options

This treadmill should only be used with the proper power cord and power outlet. Several power cord options (shown below) are available from LifeSpan. We do our best to include the correct power cord with the treadmill for your area. In the event that the correct power cord is not included in the packaging please contact your local distributor.LifeSpan TR800B Treadmill Base Power Cord OptionsWarning-icon.png Do not use extension cords between the treadmill and power outlet.
Warning-icon.pngDo not plug into a GFI outlet or circuit as it may trip the breaker.

Maintenance and Tips

Belt Lubrication

Use only 100% silicone and avoid using aerosol silicone sprays which include additives and petroleum distillates. One ounce of silicone should be used for each application. LifeSpan offers 100% silicone lubricant that can be ordered at
The walking belt should be lubricated with one fluid ounce every 50 hours of use or three months, whichever comes first.
To lubricate, unplug your treadmill.

  1. Power off your treadmill and unplug it from the power outlet.
  2. Starting toward the front (motor end) of your treadmill, slide your hand underneath the belt and create separation between the deck and belt.
  3. Slide the lube tube as close to the center of the deck as possible.
  4. While gently applying controlled pressure to the squeeze bottle, apply approximately ½ oz (1/8 of the bottle) to the underside of the belt. Apply as close to the middle of the belt as possible, since this is where your feet make contact.
  5. Move the belt with your hands or feet so that you apply a full ounce on the entire inner surface of the belt.
  6. Plugin the treadmill, power it on, and run the belt without walking on it at 3 mph for 3 minutes to disperse the treadmill lubricant evenly.

Note: When lubricating the belt, make sure the treadmill is on a surface that can be easily cleaned. After lubricating clean any excess silicone off the walking surface of the belt and side rails.LifeSpan TR800B Treadmill Base walking

Daily Cleaning

It is recommended to wipe the treadmill down after each use to keep the treadmill clean and dry. A mild detergent may be used at times to help remove all dirt and salt from the belt, painted parts, and the display.

Monthly Cleaning

This cleaning includes removing the motor cover and cleaning around the motor and electronics. It is recommended to clean the motor compartment if the treadmill is in an area where there might be plush carpet fibers that could get pulled up into the motor compartment. It is a good idea at this time to tighten all assembly hardware and check the power cord for damage, or anything else that would indicate the need for service.

Safety and Integrity

The safety and integrity designed into the machine can only be maintained when the treadmill is regularly examined for damage and repaired. Worn or damaged components shall be replaced immediately or the treadmill is removed from service until the repair is made. Pay special attention to components most susceptible to wear.
Warning-icon.pngWARNING: Keep treadmill stable on flat ground.
Warning-icon.pngWARNING: Unplug the power cord before removing the motor cover.
Warning-icon.pngIMPORTANT: If service is required, turn the power off and remove the power cord to ensure the unit cannot be used. Let all other users know the treadmill needs service.
Warning-icon.pngCAUTION: Acidic cleaning detergents may damage painted or powder-coated surfaces and should not be used. Such cleaners may void the LifeSpan warranty.

Belt Tensioning

If the belt begins to slip and needs to be tensioned, tension bolts are accessible from the back of the treadmill. Before tensioning the belt, start the treadmill and set the speed to 3 mph (5 kph).
A. Using a 6 mm Allen wrench, included in your hardware bag, turn the right and left tension bolts 1/2 turn clockwise.
B. Test to see if the slipping is eliminated. If the belt slips repeat step A and test again.

Note: Adjusting one side more than the other will cause the belt to drift to the side of the treadmill and will require belt alignment. Check to be sure the running belt is still aligned. If belt alignment is off refer to the Belt Alignment section.LifeSpan TR800B Treadmill Base ClockwiseWarning-icon.pngCAUTION: DO NOT tighten more than 2 full turns on each side.
Over tensioning the belt can cause unnecessary friction and wear and tear on the belt, motor, and electronics.

Belt Alignment

A. Press Start, then increase the treadmill speed to 3 mph (5 kph).
B. Stand behind the treadmill to see which way the belt is drifting.
C. If the belt drifts to the left, turn the left adjustment bolt 1/4 turn clockwise and the right adjustment bolt 1/4 turn counter-clockwise. (See FIG. 1)
D. If the belt drifts to the right, turn the left adjustment bolt 1/4 turn counter-clockwise and the right adjustment bolt 1/4 turn clockwise. (See FIG. 2)
E. Observe the alignment for two minutes. Repeat steps A-D as needed.LifeSpan TR800B Treadmill Base fig

Moving the Treadmill Base
  1. Make sure the ON/OFF switch is turned OFF. Unplug the power cord and data cable from the treadmill.
  2. Make sure nothing is on or near your treadmill which might spill, be knocked off, or prevent the treadmill from moving.
  3. Place both hands under the support bar located under the back of the walking belt to make sure you have a solid lifting point.
  4. Lift the back of the treadmill and roll to the desired location.LifeSpan TR800B Treadmill Base fig 1

Warning-icon.pngCAUTION: When lifting, use proper safety precautions and lifting techniques. Bend your knees and elbows, keep your back straight and lift evenly with both arms.
