In short
Unplug the pad, lift one edge of the belt and apply the lubricant the manual specifies, usually 100% silicone, in a line down the centre of the deck under the belt. Repeat on the other side, then walk slowly for a few minutes to spread it. Many makers suggest a small amount, often about 10 to 15 ml, every few weeks to few months depending on use. Always follow your manual.

Between the belt and the deck there is friction every time you take a step. A thin film of lubricant keeps that friction low, which helps the belt run smoothly, cuts strain on the motor and reduces wear on both surfaces. A dry belt can squeak, judder or trigger overload errors. Lubricating is a short job you can do with the pad in place. This guide covers which lubricant to use, how much, exactly where to apply it, and how often. Makers differ, so check your manual: some belts are pre-waxed and should not be lubricated at all.
Do you need to lubricate a walking pad?
Most walking pads and home treadmills need periodic lubrication. Many come with a small bottle of silicone oil in the box, which is a strong hint. A few treadmills use a pre-waxed belt or a deck designed to run without added lubricant, and adding silicone to those can cause problems. Your manual is the authority here.
Signs the belt may need lubricating include a squeak or hiss as you walk, the belt hesitating under your foot, a rougher feel on the underside of the belt, or overload or motor error codes. See walking pad making a noise and treadmill belt slipping for other causes.
Silicone vs wax and what not to use
Use the lubricant your manual names. If it says silicone, choose a product labelled 100% silicone for treadmills. Avoid sprays that are mostly solvent, and never use petroleum-based or general-purpose oils.
| Type | Used on | Notes |
|---|---|---|
| 100% silicone oil | Most walking pads and home treadmills | Usually supplied in a squeeze bottle with a long nozzle |
| Wax | Some commercial and pre-waxed belts | Only where the maker specifies it |
| Household oils, WD-40, cooking oil | Nothing | Can damage the belt and deck |
How to lubricate the belt, step by step
- 1
Switch off and unplug the pad. Remove the safety key.
- 2
Wipe the top of the belt and the deck edges to remove dust.
- 3
If the manual says so, loosen the rear roller bolts a little so you can lift the belt. Count the turns so you can return them exactly.
- 4
Lift one side of the belt and slide the nozzle under it towards the centre of the deck.
- 5
Apply a thin line of lubricant along the centre of the deck, front to back, as the manual describes.
- 6
Repeat from the other side.
- 7
Retighten the rear bolts by the same number of turns, if you loosened them.
- 8
Plug in, start at a slow speed and walk for a few minutes to spread the lubricant evenly.
- 9
Wipe off any excess at the belt edges.
Note:Always unplug the pad before lifting the belt or putting your hands near the rollers. Keep fingers clear of the rollers when the belt is moving.
How much lubricant to use
Less is more. Many makers suggest about 10 to 15 ml per application for a walking pad, but your manual may give a different figure. Too much can let the belt slip, collect dust and leak out at the edges onto the floor. Too little leaves dry patches.
If your manual gives no amount, apply a modest line along the centre on each side, walk on it, and check the feel. You can always add a little more next time.
How often to lubricate
Makers usually tie it to use. A common pattern is roughly every 50 hours of walking, or every one to three months for regular use, but follow your manual. Heavier use, heavier users and dusty rooms all mean more frequent checks.
A simple test: unplug the pad, lift the belt edge and feel the deck. If it feels slightly slick, it is fine. If it is dry, lubricate. Keeping a note of the date helps.
| Use | Check | Typical interval |
|---|---|---|
| Under-desk walking most days | Monthly | Every 1 to 2 months |
| A few walks a week | Every 2 months | Every 2 to 3 months |
| Occasional use | Every 3 months | When the deck feels dry |
After lubricating
Check the belt is still centred and its tension feels right. If it drifts, see how to adjust a treadmill belt. A mat underneath catches any drips and protects the floor. Choosing a new pad? The best quiet walking pads and the best walking pads list belt and deck details.
