Console Operation

Start

The treadmill starts after you press the "Start" button.

Number of programs

24 preset programs and 3 modes.

Safety key function

If the safety key is removed, "E7" appears on the display and the treadmill stops immediately. After the key is put back, all data is cleared after 2 seconds.

Control knob

In display mode:

• When adjusting speed, the display shows the current speed.
• When adjusting incline, it shows the incline value.
• When no adjustment is being made, it alternates between the current speed and incline angle every 5 seconds.

In control mode:

• Start — press the knob while the treadmill is stopped: the display shows a 3-2-1 countdown and the treadmill starts.
• Pause — press the knob while the belt is moving: the treadmill enters pause mode and gradually slows to a stop. Pressing again starts a 3-2-1 countdown and resumes the workout.
• Stop — hold the knob for 5 seconds: the treadmill stops completely and all data is cleared.
• Speed adjustment — turning the knob clockwise increases speed by 0.1 km/h, turning it counterclockwise decreases speed by 0.1 km/h.
• When stopped, a short press has no effect; a long press (5 sec.) switches the treadmill fully off.

Display

Body Fat Measurement

In standby mode, press the "Program" button to go to the body mass index (BMI) test. A test icon appears on the display, and the speed window shows the parameters (Gender: 001 — Male, 002 — Female; Age — 025; Height — 170; Weight — 070; Fat test — "---").

Press the "Mode" button to go to the next step. Use the speed control knob to change the values.

When you enter the body fat test screen, the speed window shows "---" and you can start the test.

Test steps:

Hold the metal heart rate sensors with both hands for about 3 seconds. Your body fat percentage will then appear on the display. Check that the weight and height values are correct.

• Below 19% — underweight
• 25–29% — overweight
• Over 30% — obese

* These data are for reference only and are not a medical assessment.

Smart Shock Absorption

• Turn on the treadmill. While the treadmill is in standby mode, do not step on it — remove the safety key, then insert it again. Wait 5–8 seconds, stand on the side rails and hold the handrails on both sides.
• After the treadmill starts, wait a few seconds — it will determine the cushioning pressure according to the user's weight. The smart shock absorption system then completes the measurement, and the user can adjust the settings as desired.
• The running belt firmness can also be adjusted manually using the "Shock absorption +" and "Shock absorption –" buttons.

Preset Programs

The duration of one workout segment is calculated as the total set time divided by 16.

Error Codes and Troubleshooting

Care, Storage and Maintenance

Maintenance

Regular cleaning

Turn off the power before cleaning and use a minimal amount of water and soapy solution to prevent moisture from getting onto electrical parts.

Clean the running belt and other parts of the treadmill regularly. After each workout, wipe down the entire treadmill, including the console, with a mild soapy solution, then dry it thoroughly with a dry cloth. Simple care will keep the equipment looking great for many years. Do not use abrasive or rough brushes and cloths, as they may damage the surface of the equipment. Do not let cleaning agents or liquids get onto the surface of the equipment. Do not use harsh chemicals or solvents to clean the treadmill.

Lubricating the running belt

Use only lubricants recommended by the manufacturer, such as silicone treadmill lubricant. Other types and compositions of lubricants may damage the equipment.

Lubrication frequency

• Light use (less than 3 hours per week): lubricate once every 10 months.
• Heavy use (more than 7 hours per week): lubricate every 2–5 months.

Lubrication procedure

Lift the running belt, locate the caps and spread the lubricant evenly along the entire length of the belt.

After applying the lubricant, run the treadmill at 4–5 km/h and walk on it for a few minutes so that the lubricant spreads evenly over the deck.

Avoid over-lubrication

Do not apply too much lubricant, as this can make the belt too slippery and dangerous. Remove excess lubricant with a clean towel.

Running Belt Adjustment

Check and adjust the tension and alignment of the running belt to prevent wear and ensure safe operation.

Checking belt alignment

Make sure the treadmill is placed on a level surface. Run the belt at 3–8 km/h and watch how it moves. If the belt drifts to the left or right, use the adjustment bolts to correct its position.

Belt drifting to the left

• Turn the left adjustment bolt 1/2 turn clockwise.
• Then turn the right adjustment bolt 1/2 turn counterclockwise.
• Check the belt position after 1–2 minutes. If the belt has not returned to the center, repeat the procedure.

Belt drifting to the right

• Turn the right adjustment bolt 1/2 turn clockwise.
• Then turn the left adjustment bolt 1/2 turn counterclockwise.
• Check the belt position after 1–2 minutes. Repeat the adjustment if necessary.

Adjusting belt tension

• If the belt is too loose, it may slip during operation. To check the tension, run the treadmill at 1 km/h and press lightly on the belt with your foot.
• If the belt stops while the motor and rollers keep running, the tension is too loose and must be tightened.
• Turn the adjustment bolts at both ends of the belt 1/2 turn clockwise. Make sure you turn both bolts the same number of times for even tension.
• Check the tension again and make sure the belt does not slip but is not overtightened.

Avoid overtightening

• Do not overtighten the running belt, as this puts excessive pressure on the front and rear roller bearings, causing squeaking and accelerated wear.
• With correct tension, you can slightly lift the edges of the belt by 50–70 mm on both sides.

Storing the Treadmill

Recommended storage and operating conditions

• Temperature: +10…+35 °C.
• Humidity: 50–75%.
• Acclimatization: if the treadmill has been stored at low temperature or high humidity (there are signs of condensation), keep it under normal conditions for at least 2–4 hours before use. Only then may you start using the treadmill.

Warm-up and Cool-down Exercises

A successful workout program consists of three parts: warm-up, aerobic exercise and cool-down.

The warm-up is the most important part of a workout and should be done before every session. It helps warm up the body, stretch the muscles and prepare the body for more intense exercise. Repeating the warm-up exercises after your workout helps relieve muscle tension and soreness.

We recommend doing suitable warm-up and cool-down exercises as shown below:

Head rolls

First tilt your head toward your right shoulder, stretch your neck and rotate your head once clockwise and once counterclockwise; then tilt your head toward your left shoulder and make one counterclockwise rotation. Repeat.

Shoulder lifts

Raise your left shoulder and make 5 backward rotations; then raise your right shoulder and make 5 backward rotations, alternating sides.

Side stretch

Raise your arms above your head, then grasp your right wrist with your left hand and reach upward until you feel your right arm fully stretched. Hold for 5 seconds before switching to the other arm.

Quadriceps stretch

Holding onto a wall with your right hand for balance, pull your left foot back with your left hand, bringing the heel as close to your buttock as possible. Hold for 15 seconds, then repeat with the other leg.

Inner thigh stretch

Sitting on the floor, put the soles of your feet together, clasp them with both hands and pull them in as close to your body as possible. Slowly press down on both heels and hold this position for 15 seconds.

Toe touch

Slowly bend forward, relax your back and shoulders and reach for your toes. Bend as low as you can and hold the position for up to 15 seconds.

Hamstring stretch

Sit down, straighten your right leg and bend your left leg. Hold your left ankle with your left hand and pull it inward so that your left foot is as close to your body as possible, with the sole against the inner side of your right thigh. Then lean your body forward and reach both hands toward your toes — the deeper the stretch, the better. Hold this position for 15 seconds, then switch legs.

Calf stretch

Lean against a wall with both hands, tilt your body at a 45-degree angle to the floor and alternately move your left and right legs back, as if walking.
