This guide provides clear, step-by-step instructions to help you complete this maintenance safely and correctly, ensuring many more miles on your favorite fitness equipment.
How To Lube Treadmill Belt Horizon
Before you begin the lubrication process, you need to gather the right supplies and prepare your treadmill. Having everything on hand will make the job quicker and easier.
Gather The Necessary Supplies
You will need a few specific items to properly lubricate your Horizon treadmill. Using the correct materials is essential.
- 100% Silicone Lubricant: This is the only type of lubricant you should use. Horizon specifically recommends 100% silicone. Do not use WD-40, petroleum-based oils, or spray silicone with additives, as these can damage the belt.
- A Clean Lint-Free Cloth: For wiping the deck and cleaning any debris.
- A Phillips Head Screwdriver: For adjusting the belt tension if needed.
- A Treadmill Lubricant Applicator (Optional): Some silicone lubricants come with a thin nozzle or applicator tube that makes applying under the belt simpler.
Prepare Your Treadmill Space
Create a safe and clear workspace around your treadmill. Unplug the machine from the electrical outlet. This is a critical safety step to prevent any accidental startup while your hands are near the belt. Clear any items from around the base and make sure you have good lighting.
Check Belt Tension And Alignment First
Before applying lubricant, it’s a good idea to check the belt’s tension and alignment. A belt that is too tight won’t benefit as much from lubrication, and a misaligned belt can wear unevenly. To check tension, you should be able to lift the belt about 2-3 inches off the deck at the midpoint. If it’s tighter or looser, you may need to adjust it using the rear roller adjustment bolts.
Locate The Application Area
You do not need to remove the treadmill belt to lubricate it. The lubricant is applied between the belt and the deck. You will need to lift the edges of the running belt to access the deck underneath. Focus on the area where you typically run or walk, which is usually the center two-thirds of the deck length.
Step By Step Lubrication Instructions
Follow these steps carefully to ensure you apply the lubricant correctly and effectively.
Step 1: Lift The Treadmill Belt
Stand at the side of the treadmill. Firmly grip the edge of the running belt and lift it upward. You should be able to create a gap large enough to see the deck board underneath. You might need to slide your hand under slightly. Do this at a point about halfway down the length of the treadmill deck.
Step 2: Apply The Silicone Lubricant
With the belt lifted, apply the 100% silicone lubricant directly onto the deck board. Do not apply it to the belt itself. Use the recommended pattern for best coverage.
- Apply a thin, 2-inch wide line of lubricant down the center of the deck, from near the front roller to near the rear roller.
- Then, apply two more parallel lines, one about 3-4 inches from the left edge and one the same distance from the right edge of the deck.
- The total amount is usually about 1/2 ounce or a 15ml packet, but refer to your treadmill manual. The goal is a thin, even layer, not a puddle.
Step 3: Spread The Lubricant By Running The Belt
After applying the lubricant, lower the belt. Now, you need to spread it evenly. Reconnect the power cord. Stand on the side rails, not the belt. Start the treadmill at a very slow speed, like 1 or 2 mph. Let it run for 2-3 minutes. This allows the belt to naturally spread the silicone lubricant across the entire deck surface. You may hear some squeaking initially which should fade as the lubricant distributes.
Step 4: Final Check And Cleanup
After running the belt, turn off and unplug the treadmill again. Wipe any excess lubricant from the edges of the deck or the belt with your clean cloth. Check the belt tension one more time by feel. Your Horizon treadmill belt is now properly lubricated and ready for use.
How Often Should You Lubricate Your Horizon Treadmill
The frequency of lubrication depends on how often you use your treadmill. A general rule is to lubricate it every three months or every 130 miles of use, whichever comes first. However, your specific model’s manual is the best source for this information.
Signs Your Treadmill Needs Lubrication
Don’t wait for a set schedule if you notice these signs. They indicate that the belt and deck are creating excess friction.
- A squeaking, squealing, or rubbing noise coming from the belt area during use.
- The belt feels like it’s sticking or hesitating, especially at lower speeds.
- You can feel more resistance when manually moving the belt by hand.
- The motor seems to be laboring more than usual, or the console shows an error code related to motor or belt performance.
Common Mistakes To Avoid
Avoiding these common errors will protect your treadmill from damage and ensure the lubrication is effective.
Using The Wrong Type Of Lubricant
This is the most critical mistake. Only use 100% silicone treadmill lubricant. Household oils or general-purpose sprays will degrade the belt material and the deck, leading to permanent damage and costly repairs.
Over-Lubricating The Deck
More is not better. Applying too much silicone can cause the belt to slip, which creates a safety hazard and can strain the motor. It can also make a mess, attracting dust and debris that acts like sandpaper. A thin, even layer is all that’s needed.
Neglecting Belt Tension And Alignment
Lubrication is not a fix for mechanical issues. If your belt is too loose, too tight, or misaligned, lubricating it will not solve the underlying problem. Always check tension and alignment as part of your regular maintenance routine.
Troubleshooting Post-Lubrication Issues
If you experience problems after lubricating your treadmill, here are some likely causes and solutions.
Belt Is Slipping Or Hesitating
If the belt slips underfoot after lubrication, you likely used too much lubricant. To fix this, you need to remove the excess. Sprinkle a small amount of talc-free baby powder or treadmill belt powder under the edges of the belt. Run the treadmill at a slow speed for a few minutes to distribute it, which will absorb the excess silicone. You may need to repeat this.
Unusual Noises Persist
If squeaking continues after lubrication, the issue might not be the belt-to-deck friction. Other sources of noise include:
- A dry or worn rear roller bearing.
- The motor drive belt needing adjustment or replacement.
- Debris caught in the roller or motor area.
Inspect these areas if noise continues. Sometimes the deck itself can become warped over time, which lubrication won’t fix.
Error Codes After Maintenance
If your treadmill displays an error code after you’ve worked on it, first double-check that all safety keys are properly inserted and that the power cord is fully seated. Some Horizon models have a calibration sequence that might need to be run if the belt tension was significantly adjusted. Consult your owner’s manual for specific error code meanings.
FAQ About Lubricating Horizon Treadmill Belts
Can I Use Any Silicone Spray On My Treadmill?
No, you cannot. You must use 100% silicone lubricant formulated for treadmills. Many general silicone sprays contain petroleum distillates or other additives that can break down the belt fibers and the deck board. Always check the label to ensure it says “100% silicone” and is recommended for treadmill use.
How Do I Know If My Horizon Treadmill Is Self-Lubricating?
Some newer Horizon treadmill models feature a self-lubricating system. You can check your owner’s manual or the product specifications online. If your model is self-lubricating, it will have a lubricant reservoir or cartridge that you fill periodically, and the machine distributes it automatically. You do not need to manually lift the belt and apply silicone.
What If I Haven’t Lubricated My Treadmill In Years?
If it’s been a very long time since lubrication, the deck and belt may have experienced accelerated wear. You should still perform the lubrication process. After applying the silicone and running the belt, monitor for excessive slipping or noise. If performance does not improve, the deck may be worn out and require inspection or replacement by a technician.
Is There An Alternative To Liquid Silicone Lubricant?
Some manufacturers offer pre-measured silicone lubrication sheets or packets. These are designed for convenience and to prevent over-application. They are still 100% silicone. You simply place the sheet or empty the packet under the belt in the correct pattern. They are a good option if you are concerned about using too much liquid lubricant.
Should I Clean The Deck Before Applying New Lubricant?
It is a good practice to wipe the deck with a dry, lint-free cloth before applying fresh lubricant. This removes any dust or partical debris that could mix with the silicone and create an abrasive paste. However, you do not typically need to use soap or solvents to strip old silicone, as the new application will blend with it.
