How To Lubricate A True Treadmill

Keeping your treadmill running smoothly is key to a good workout and a long machine life. If you own a TRUE treadmill, regular care is essential. This guide will show you exactly how to lubricate a TRUE treadmill the right way. Proper lubrication reduces wear on the belt and deck, making your runs quieter and preventing costly repairs.

How to Lubricate a TRUE Treadmill

Before you start, it’s crucial to check your treadmill’s manual. TRUE has used different lubrication systems over the years. Some older models require manual application, while many newer ones have a self-lubricating system. Using the wrong method or product can void your warranty. Always confirm your model’s requirements first.

What You’ll Need

Gathering the right supplies makes the job quick and easy. You won’t need many tools. Here’s your checklist:

  • TRUE Treadmill Lubricant: This is the most important item. TRUE recommends their specific silicone-based lubricant for manual application. Using a generic oil or silicone spray can damage the belt.
  • Clean Rags or Paper Towels: For wiping away any old residue or excess lubricant.
  • Allen Wrench Set: Usually needed to loosen the belt for access.
  • A Vacuum or Soft Brush: To clean the deck and belt area before you start.
  • Isopropyl Alcohol (optional): For a deeper clean of the deck if it’s very dirty.

Step-by-Step Lubrication Guide

Follow these steps carefully to ensure you lubricate your TRUE treadmill correctly and safely.

Step 1: Safety First & Preparation

Unplug the treadmill from the wall outlet. This is non-negotiable for your safety. Move the treadmill to a clear space if you can, giving you room to work. Take a moment to visually inspect the belt and deck for any obvious damage or excessive wear.

Step 2: Clean the Running Deck

Lift the belt on one side and peek underneath. Use your vacuum hose or a soft brush to remove any dust, hair, or debris from the deck surface. A clean deck allows the lubricant to spread evenly. If there’s sticky residue, a rag lightly dampened with isopropyl alcohol can help, but make sure the deck is completely dry before moving on.

Step 3: Loosen the Treadmill Belt

Locate the tension bolts at the rear of the treadmill. Using the correct size Allen wrench, turn each bolt counter-clockwise about a quarter to a half turn. You don’t need to loosen them much—just enough so you can lift the belt easily with your fingers. The belt should have about 2-3 inches of lift in the middle.

Step 4: Apply the Lubricant

If your model requires manual lubrication, this is the key step. With the belt loosened, lift it up along one side. Apply a thin, continuous bead of TRUE lubricant along the deck, about 1-2 inches from each edge. Do not over-apply. A little goes a long way. Then, lift the belt on the other side and repeat the process, creating two long lines of lubricant down the deck.

Step 5: Re-Tension and Distribute the Lubricant

Once the lubricant is applied, re-tighten the rear tension bolts you loosened earlier. Turn them clockwise until they are snug, but do not over-tighten. Now, plug the treadmill back in. Stand on the side rails, start the belt at a slow speed (around 2-3 mph), and let it run for 2-3 minutes. This spreads the lubricant evenly across the entire deck surface.

Step 6: Final Check and Cleanup

After the distribution run, stop the treadmill and unplug it again. Wipe off any excess lubricant that may have seeped out from the edges with a clean rag. Do a final check to ensure the belt is centered and has proper tension. You’re all done!

Checking a Self-Lubricating TRUE Treadmill

Many newer TRUE treadmills have an Ez-Lube or similar automatic system. For these, you don’t apply lubricant manually. Instead, you need to check the lubricant reservoir. It’s usually located near the front of the machine under the hood. Consult your manual to find it. If the reservoir is low or empty, simply fill it with the recommended TRUE lubricant until the indicator shows full. The machine will do the rest, releasing lubricant at set intervals.

How Often Should You Lubricate?

Frequency depends on how much you use your treadmill. A good general rule is to check lubrication every 3 months or every 130 miles of use, whichever comes first. If you notice the belt sounding louder or feeling sluggish, it might need attention sooner. For self-lubricating models, check the reservoir level every 1-2 months.

Common Mistakes to Avoid

  • Using the Wrong Lubricant: WD-40, household oils, or general-purpose silicone sprays are not suitable. They can degrade the belt and deck.
  • Over-Lubricating: Too much lubricant can cause the belt to slip and attract more dirt. It can also create a mess.
  • Forgetting to Re-Tension the Belt: A belt that’s too loose will slip; one that’s too tight will wear out fast and strain the motor.
  • Neglecting to Clean First: Applying lube over dirt just creates an abrasive paste that damages the deck.

FAQs About TRUE Treadmill Lubrication

Can I use a different brand of treadmill lubricant?

It’s strongly recommended to use TRUE’s own silicone lubricant. Other brands may have different formulas or consistencies that could affect performance. Using a non-approved lubricant might void your warranty, so it’s not worth the risk.

How do I know if my treadmill belt needs lubrication?

Listen and feel. A dry belt often makes a squeaking or rubbing noise, especially near the rear roller. You might also feel more resistance when walking or running, as if the belt is sticking. If you lift the belt and the deck looks dry or feels rough, it’s probably time.

What if my belt still slips after lubrication?

Slipping is usually a tension issue, not a lubrication one. First, ensure you didn’t over-lubricate. If the belt is properly tensioned and still slips, the belt or deck may be worn out and need replacement. It’s a good idea to contact TRUE customer support for advice.

Is it hard to replace the lubricant reservoir?

No, replacing the reservoir bottle on a self-lubing system is typically very simple. It usually just twists out and a new one twists in. You can order replacement bottles directly from TRUE or authorized dealers. Make sure you get the correct part for your specific treadmill model.

Regular maintenance, including knowing how to lubricate a TRUE treadmill, is the best way to protect your investment. It ensures quite, efficient operation and extends the life of your machine for years of reliable workouts. Always refer to your owner’s manual for model-specific details and keep that bottle of TRUE lubricant handy.
