Overview

Get the results you want whether you're in training or trying to shed a few pounds with the Livestrong LS8.0T folding treadmill. The LS8.0T is equipped with a 2.5-horsepower continuous-duty motor, powerful enough to deliver speeds of 0.5 to 12 miles per hour and an incline range of 0 to 12 percent (in 0.5-percent increments). As a result, you don't have to compromise when working out--a must when training hard. The treadmill is also extremely comfortable thanks to the MaxComfort cushioning system. The system's adjustable cushioning technology allows you to customize your workout with a softer or firmer feel. With more support for each part of your stride, you'll recover quicker between workouts.

Updating the Firmware (Couldn't get this to work)

Mac OS

1. Download the “ROM.bin” file in the references section below.
2. Insert your LIVESTRONG USB flash drive, allowing a few seconds for it to be installed into your computer.
3. By using the Finder tool, locate the flash drive in the “Devices” section.
4. Open up the “LS” folder and look for a folder named “FW”.
5. If “FW” does not exist, create a new folder by selecting File > New Folder, and name the folder “FW”.
6. Copy the ROM.bin file to your “FW” directory.
7. That’s it! Your LIVESTRONG USB flash drive now contains the new firmware needed to update your equipment.
8. Refer to your Owners Manual for instructions on how to update your equipment using the file copied to your USB drive.

Frequently Asked Questions

What brand of lubricant should I use on the running deck?

All LIVESTRONG® Fitness treadmills use lubricant that is 100 percent silicon. Important: it must be 100 percent silicon and not have other ingredients mixed in. It comes in oil or spray, but oil usually lasts longer.

Creating Your Own Programs

Using a USB drive formatted FAT32:

• create a folder structure as follows: Main folder called LS, with 3 sub-folders underneath named: FW, PROGRAMS and USERS:

We are interested in the XML under levels. You can define multiple difficulty levels.

Other observations:

• Fails to function properly if <6> has no values set to 1
• Anything you specify with a Repeat value of 1 will repeat (in the defined order) to get to the desired time specified in <t>.
• Comments between level and events cause the time not to get passed along

Plug your USB key in, your Livestrong treadmill and you will given the option to import the new routine.
