Servicing your product

It takes care of you, so you should do the same for it. Regular maintenance is necessary to preserve the performance of your equipment and extend its service life.

Maintenance after each use

1. Turn off and unplug your treadmill.

2. Apply a little gentle detergent to a pure cotton cloth.
Do not spray detergent directly onto your treadmill and do not use ammonia- or acid-based cleaning products.

3. Wipe down the console and screens.

4. Wipe any dust and marks from the handrails, footrests, frame and motor cover.
You should also wipe the platform alongside the belt.

Regular maintenance

Tighten the screws and bolts once a month.

Lubricate the deck after 200 kilometres of use.

Lift or move your treadmill to vacuum underneath it.

Storage tips

How to check if your running belt has the proper tension

The tension on the W500's running belt should be set to 0.76 (+/- 0.03). This is the motor belt tension.

After checking the tension on the console:
- If the figure is too low, you need to tighten the running belt.
(Tightening is done by turning the roller's two rear wheels clockwise).

- If the figure is too high, you need to loosen the running belt.
(Loosening is done by turning the roller's two rear wheels anti-clockwise).
A half key turn = 0.03

For the setting: select the "Running belt tension" tab in the MAINTENANCE section.

How to check the tension on the console:
1. Stand on the footrests.
2. With the safety key removed, press and hold the "START" and "STOP" buttons for three seconds.
3. The console will display the word "start". Press the "START" button and insert the safety key.
4. The treadmill will start at 5 km/h and display the running belt tension. (Make any adjustments necessary).
5. Press the "STOP" button.
