Thank you for selecting the revolutionary PROFORM

®

LX 450 treadmill. The LX 450 treadmill combines ad-

vanced technology with innovative design to help you

get the most from your exercise program in the conve-

nience and privacy of your home. And when you’re not

exercising, the unique LX 450 treadmill can be folded

up, requiring less than half the floor space of other

treadmills. 

For your benefit, read this manual carefully before

you use the treadmill. If you have questions after

reading this manual, please see the front cover of this

manual. To help us assist you, note the product model

number and serial number before calling. The model

number of the treadmill is PFTL31404.1. The serial

number can be found on a decal attached to the tread-

mill (see the front cover of this manual for the location). 

To avoid a registration fee for any service needed

under warranty, you must register the treadmill at
