A NordicTrack treadmill can be a significant financial investment. As of September 2010, the treadmills listed on the NordicTrack website range from $600 to $3000. You will get longer life out of your treadmill if you perform some basic maintenance tasks. The tasks required will vary depending on the age and model of your treadmill. For example, many of the newer NordicTrack treadmills don't require any belt lubrication. Always consult your owner's manual for specific maintenance and care instructions.
Things You'll Need
Clean the treadmill after every workout. Use a clean, dry cloth to wipe the treadmill belt, side rails, console and handles.
Lubricate the treadmill belt. Check to make sure your model requires lubrication. NordicTrack recommends lubricating the belt after every 12 to 15 hours of use. Use only lubricant obtained through or approved by NordicTrack. Wipe the treadmill deck under the walking belt with a dry, clean cloth. Lift the treadmill belt on one side and apply the lubricant along the length of the deck. Follow the directions on the package for the amount of lubricant to apply. Repeat on the other side. Walk on the treadmill for a few minutes to spread the lubricant.
Check the tension of the walking belt. Lift the middle of the belt on one side of the machine. The belt should raise 3 to 4 inches off the deck. If the belt requires tightening, use an Allen wrench to turn the rear roller adjustment bolts--located at the end of the treadmill--clockwise 1/4 of a turn. Depending on the model of your NordicTrack treadmill, you will either turn both bolts or just the right bolt to adjust the belt tension.
Inspect the nuts and bolts. Walk around your treadmill regularly and check for any loose hardware. Tighten as needed.
Do not attempt to service the treadmill motor yourself. Contact your NordicTrack dealer for professional service.
