Regular treadmill maintenance is essential — and lubricating the belt is one of the most important tasks. A dry belt can cause friction, noise, motor strain, and even shorten the lifespan of your machine.

In this simple guide, you’ll learn how to lubricate your treadmill belt at home, with no special tools and in just a few easy steps.

🛠️ Why Lubricating Your Treadmill Belt Matters

Lubrication reduces:

• Friction between the belt and deck
• Noise during running
• Wear on the motor
• Risk of sudden stops or belt slipping

Most treadmill manufacturers recommend lubricating every 3 months or every 40 hours of use.

✅ What You’ll Need

• ✅ 100% silicone treadmill lubricant (Check your treadmill manual for recommended type)
• ✅ Clean cloth or towel
• ✅ Allen wrench (to loosen the belt)
• ✅ Gloves (optional)

❌ Never use WD-40, petroleum-based oils, or cooking sprays.

📋 Step-by-Step Guide to Lubricate Your Treadmill

Step 1: Turn Off and Unplug the Treadmill

Safety first! Always unplug the treadmill before doing any maintenance.

Step 2: Loosen the Treadmill Belt

Use an Allen wrench (usually provided with the machine) to loosen the belt at the rear roller.

• Turn both rear roller bolts counterclockwise about 1–2 turns
• Do not remove the bolts — just enough to slide your hand underneath

Step 3: Apply the Lubricant Under the Belt

• Lift the belt gently on one side
• Apply about 1 oz (2–3 sprays or drops) of silicone lube directly to the center of the deck
• Repeat on the other side

🎯 Focus on the area under where your feet land — the middle of the deck.

Step 4: Tighten the Belt

Turn the roller bolts clockwise to retighten the belt.

• Keep both sides even to avoid belt misalignment
• Test for correct tension (you should be able to lift the belt slightly in the center)

Step 5: Walk on the Treadmill

Plug the treadmill back in and turn it on.

• Walk at 1–2 mph (2–3 km/h) for 3–5 minutes to spread the lubricant evenly
• Avoid running immediately after lubrication

Step 6: Wipe Excess Lubricant

Use a clean cloth to remove any excess silicone that may seep out from the sides.

🧼 Bonus Tip: Keep Your Treadmill Clean

After every few uses:

• Wipe down the belt and console
• Vacuum around and under the machine to prevent dust build-up
• Check for unusual sounds or belt misalignment

⚠️ Signs Your Treadmill Needs Lubrication

• Belt feels dry or rough underneath
• Loud squeaking or grinding noise
• Belt sticking or slipping
• Burning smell from motor

If you notice these, don’t wait — lubricate immediately.
