Setting up and using your product

Thank you for purchasing a Domyos product. We've gathered together some handy tips to help you when you first set up and use your machine.

Quick start

You can start exercising when the word ""GO"" appears on the console.

The console comes on after one second of exercising. Alternatively, you can press the "..."button in the centre.

Pressing and holding the "..." button will enable the (AUTO) mode that will automatically scroll through and display indicators, one second at a time, or switch the treadmill off (OFF).

How does the target mode work?

When the word ""GO"" appears on the console, press on the "..." button in the centre to scroll through the various objectives: TIME, DISTANCE, CALORIES, NUMBER OF STEPS.

You can choose one objective at a time.

Use the "+" and "-" buttons to adjust the objective value. The counter on the display will start running when you take your first steps.

The counter will stop as soon as you reach your objective. 

Adjusting the speed

Use the lever on the right-hand side of the treadmill to adjust the intensity level.

To speed up, move the lever towards the "+" symbol. 

To slow down, move the lever towards the "-" symbol.

Directions for use

1. If you are a beginner, start by training for several days at a low speed, without overexerting yourself, and taking rest periods if necessary. Gradually increase the number or duration of your workouts. During your workout, be sure to ventilate the room where your treadmill is located.

2. Cooling down: After each workout, walk a few minutes at a low speed to gradually bring the body to rest. This cool-down phase helps bring your cardiovascular and respiratory systems, blood flow and muscles back down to normal. This makes it possible to eliminate counter effects such as lactic acid build-up, which is one of the major causes of muscle pain (cramps and muscle aches).

3. Don't forget to stretch. We recommend that you stretch and hydrate after each workout to relax your muscles and promote recovery.

How can you find out how much time you've spent on the treadmill?

Press the "..." button twice to display the total time.

Press the "..." button four times to return to the "GO" screen.

How can you find out the total distance you've travelled on the treadmill?

How can you change the stride length?

To access your treadmill's settings screens, wait for the "GO" screen to appear on the console and then hold the "+" and "-" buttons down simultaneously for three seconds.

The default value for the stride length on the settings screen is 0.70m.

Use the "-" and "+" buttons to adjust the value. Press the "..." button six times to confirm and return to the GO screen.

Calculating your average stride length couldn't be easier:

1. Walk for 100m and count the number of strides.

2. Divide the distance by the number of strides to calculate your average stride length.

E.g.: 100m ÷ 150 strides = 0.66m

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 small amount of mild all-purpose cleaner to a pure cotton cloth. Do not spray the cleaner directly onto the treadmill and do not use ammonia or acid cleaners.

 3. Wipe down the console and screens.

 4. Remove any dust or stains on the ramps, handrails, footrests, frame and motor hood. Remember to also wipe the platform alongside the running belt. Do not clean under the running belt.

Regular maintenance

Tighten the screws and bolts once a month.

Lubricate the deck after 200 kilometres of use.

Lift or move your equipment to vacuum underneath it.


Storage tips

Do not leave in a damp place or outdoors.

Do not leave your treadmill in direct sunlight or out on the terrace as this may cause the liquid crystals in the console to expand.

Place a standard floor mat (Domyos Training Mat) under your treadmill.

Use restrictions

For home use only. 

Maximum user weight: 110 kg.

Centring the running belt

If a gap appears at one side of the running belt, simply walk down that side until the belt moves back in its original position and the gap disappears.

Running belt tension

The running belt is a part that can wear and work loose over time.

If you can feel it jolting when you're using the treadmill, it means that it's not tight enough.

Turn the two adjustment screws a half turn clockwise to tighten the belt.

Keep doing this until the belt runs freely, without jolting. Warning: if you tighten the belt too much, this will increase the intensity level and may damage the rollers.

Running belt lubrication

It is important to do this regularly (every 200 hours of use) to extend your treadmill's life.

Please use Domyos lubricant only (Ref: 8326425). You can order it from your Decathlon store or online from our website: https://www.decathlon.fr/p/kit-lubrifiant-pour-tapis-de-course/_/R-p-119636?mc=8326425 1 and 2. Two sprays to the left and right of the running belt will suffice. 3. After spraying, walk for a minute or two on your treadmill to ensure the lubricant spreads evenly across the running belt.
