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.

What programmes are available?

This treadmill offers 24 pre-set programmes that vary the speed and incline.

The programmes are divided into several segments. Each segment corresponds to a time, speed and incline setting. Please note: two successive segments can have the same settings. You can modify the speed or incline to suit your level at any time during the programme.

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.

Centring the running belt

You will need the 6mm Allen key (BTR) that came with your treadmill: 

1.  Start your treadmill at a low speed (4km/h).2.  Insert the key into the screw on the side where the running belt is off-centre.3. Turn it a quarter turn clockwise (wait 30 seconds between each quarter turn) until the belt is back in the correct position.


Running belt tension

The running belt is a wearing part that becomes loose over time. Re-tighten it as soon it begins to go slack (sliding sensation, jerky motion).


1&2. Turn the two adjustment screws a half turn clockwise (repeat if necessary, but make sure you don't over-tighten the belt).


3. The belt is properly tightened if you can lift the edges 3 to 5 cm on each side.

Running deck lubrication

It's important to do this regularly (every 200 hours of use) to keep your treadmill working as long as possible.  1 & 2. Simply spray twice underneath the running belt on the right and on the left.  3. Then set your treadmill off at 5 km/h for 5 minutes, without standing on it.

Preventative maintenance

1. Check the motor and the drive belt every 600 hours of use or every 3600 km*2. Replace the running belt every 500 hours of use or every 3000 km*3. Replace the running deck every 700 hours of use or every 4200 km*4. Replace the rollers every 600 hours of use or every 3,600km*


*To find out the number of hours of use or the total distance run, go to the FAQ and read " HOW TO FIND OUT THE DISTANCE RUN AND HOURS OF USE ON YOUR TREADMILL" in the SETTING UP AND USING YOUR PRODUCT section.

Regular maintenance

Regular maintenance is necessary to preserve the performance of your appliance and extend its service life. To get rid of any annoying noises coming from your treadmill, remember to

                       Tighten the screws and bolts once a month.

                       Lubricate the running belt after 200 hours of use.

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



                      Turn off and unplug your treadmill.

                      Apply a small amount of gentle universal cleaner to a pure cotton cloth. Do not spray the cleaner directly onto the treadmill and do not use ammonia or acid cleaners.

                      Wipe the console and screens.

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