General information about treadmills
Visible seam on the treadmill belt
A visible seam on the treadmill belt is not a defect, but a normal feature of high-quality treadmills resulting from the manufacturing process. It is created during the production of the treadmill belt and is part of its design.
As the treadmill is used, the belt adjusts – as a result, the seam generally becomes less noticeable. The seam has no effect on the treadmill’s function, performance or safety. The treadmill can be used safely and without restriction.

FAQ: Visible seam on the treadmill belt
There is a visible seam on the treadmill belt – is this a defect?
No. The visible seam is not a defect, but a normal feature of high-quality treadmills resulting from the manufacturing process.
Why is there a seam at all?
The seam is created during the production of the treadmill belt and is part of its design.
Will the seam become less visible over time?
Yes. In many cases, the seam becomes less noticeable as the treadmill belt adjusts with use.
Does the seam affect the treadmill’s function or safety?
No. The seam has no effect on the treadmill’s function, performance or safety. The treadmill can be used without restriction.
Can I receive a discount or compensation because of the seam?
No. Since this is not a defect and neither performance nor safety is affected, no discount or compensation is provided.
Do I need to do or take anything into account?
No. No action is required. Normal use is sufficient.
Static electricity on treadmills
The slight “electric shock” you may feel on a treadmill is caused by static electricity, not by a device defect. This phenomenon is common with treadmills, particularly in dry conditions.
Causes of static electricity
Static electricity builds up through friction between your body, clothing, shoes and the treadmill. Dry air in winter or when the heating is on, synthetic shoe soles and fabrics such as polyester can significantly increase this effect.
Running creates continuous friction, which increases the charge – when you touch the handles, you can feel it discharge.
Solutions & tips
Use the safety clip
Always use the safety clip to avoid continuous contact with the handles. This reduces the discharge when you grip them.
Further ways to reduce static electricity
Wear cotton clothing and shoes with flat soles. Increase the humidity using a humidifier, or wipe the belt with fabric softener.
A floor protection mat reduces vibrations and dust, which helps reduce static electricity.
Which oil should I use for the treadmill?
Suitable: 100% pure silicone oil. Viscosity: 300–1000 cSt (standard: 1000 cSt).
Not suitable: Oils containing additives or solvents, e.g. WD-40, motor oil or sewing machine oil, as well as silicone sprays containing propellants or solvents.
The instructions in the device’s user manual always take precedence.
