Frequently Asked Questions

How often should I lubricate my NordicTrack treadmill?
Most NordicTrack treadmills should be lubricated every 3-6 months or every 150 hours of use, whichever comes first. Heavy usage may require more frequent lubrication.
What type of lubricant should I use for my NordicTrack treadmill?
Use only 100% silicone treadmill lubricant specifically designed for fitness equipment. Never use petroleum-based products, WD-40, or household oils as these can damage the belt and void your warranty.
Can I use my treadmill immediately after lubricating?
Yes, but start with a slow speed (1-2 mph) for the first few minutes to distribute the lubricant evenly. Avoid high-intensity workouts for the first 10-15 minutes after lubrication.
Why does my NordicTrack keep showing the Lub error after lubrication?
If the error persists, you may not have reset the maintenance reminder properly, used insufficient lubricant, or there could be a sensor issue. Check your manual for the reset procedure or contact NordicTrack support.
Is it normal for the treadmill to feel slippery after lubrication?
A slightly different feel immediately after lubrication is normal, but excessive slipperiness indicates too much lubricant was applied. Run the treadmill at low speed to help distribute excess lubricant.
