Carefully check the styrofoam and the machine itself. Some parts (bolts, screws and the like) may already be attached to the machine.

Check that all cables are properly connected. The aluminium legs are delicate and must stay straight. If you get an error message after assembly, carefully straighten the aluminium legs; this often solves the problem.

Treadmills are assembled with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

The belt should have 5–7 cm of slack. Test this by standing on the foot rails and lifting the belt on both sides. The manual explains how to adjust the belt tension. Your supplier may also have an instruction video.

Fit the folding lock/gas spring with two people: one holds the treadmill, the other installs the lock.

The manual explains step by step how to calibrate the treadmill. No longer have the manual? Request a new one from your supplier.

Possible causes:

• The sensor cables aren't properly connected or came loose during use.
• The sensors are wet, dirty or greasy. Clean them regularly.
• Calluses on your hands can interfere with the reading. In that case, use a chest strap.

Adjust the tension roller. If the belt drifts to the left, tighten the left side; if it drifts to the right, tighten the right side. Turning clockwise tightens. Your supplier may have an instruction video.

A slight thumping sound is normal. The belt is fused together in the middle and this seam can make the sound while you run.

The belt runs over a smooth plate that carries your weight. With every step, the belt is pressed onto this plate. The plate must stay smooth to prevent friction or jamming, so lubricate the deck regularly.

Every treadmill has a Safety Key that must be in place on the console. The treadmill won't work without it. Check the manual for where the key goes.

Solution 1: under the motor cover, near the roller, is a speed sensor. If it's too far from the magnet, the speed can't be read and E1 appears. Move the sensor closer to the magnet.

Solution 2: if that doesn't work, the cable may have come loose due to vibrations. Reconnect the cable to both the sensor and the circuit board.

E3 indicates a faulty circuit board. Replace the entire board; it's usually fastened with two screws. Take a photo of the board before unplugging any cables. Cables may be glued in place: gently loosen them with a small screwdriver. Then connect the new board according to the photo.

The Safety Key isn't in place on the treadmill. Attach the key to the display to continue.

Remove the Safety Key after use. Always switch off the main power before removing the key.

Carefully check the styrofoam and the machine itself. Some parts (bolts, screws and the like) may already be attached to or inside the machine.

Tighten the left pedal anticlockwise and the right pedal clockwise. If you tighten the left pedal clockwise, you may damage the thread and the pedal can no longer be used.

Check that all cables are properly connected. The aluminium legs are delicate and must stay straight. If you get an error message after assembly, carefully straighten the aluminium legs; this often solves the problem.

The heart rate cables run inside the handlebar and are often partly hidden. Pull them out as far as possible before assembly; this takes very little force.

Fit the transport wheels to the front of the machine.

Many exercise bikes are assembled with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

Inside the housing, near the flywheel, is a sensor that measures speed, just like a regular bike computer. A magnet is attached to the spoke with the sensor close by. If the sensor is too far from the magnet, the speed can't be read and the display shows E1. Locate the sensor in the housing and slide it towards the magnet until it almost touches.

First, lubricate all moving parts with silicone spray. A squeak can also occur if a screw is too tight or too loose and causes friction. Find out where the sound is coming from and adjust that screw slightly. Screws should be tight enough that you can still loosen them by hand.

First, listen for the motor. When you increase or decrease the resistance, you should hear a short sound.

• If you hear the motor, the electronics are working and the V-belt has probably slipped off. Open the housing and put the V-belt back.
• If you don't hear the motor, the motor or display may be faulty. First check that the cable running through the tube is still properly connected. If it is, replace the display. If that doesn't solve it, replace the motor.

This is probably caused by one of the pedals. Remove the pedals and refit them. Note: tighten the left pedal anticlockwise and the right pedal clockwise. Tighten them firmly. If the noise persists, contact your supplier.

Possible causes:

• The sensor cables to the display aren't properly connected or have come loose.
• The sensors are wet, dirty or greasy. Clean them regularly.
• Calluses on your hands can interfere with the reading. In that case, use a chest strap.

The console needs a firmware update. Watch the instruction video.

Connect the adapter to the back of the exercise bike, right at the bottom. Don't plug it into a random port on the display.

Only use the adapter supplied with the machine. An adapter with a different voltage or amperage can cause damage.

Carefully check the styrofoam and the machine itself. Some parts (bolts, screws and the like) may already be attached to or inside the machine.

Check that all cables are properly connected. The aluminium feet are very delicate and must stay straight. If you get an error message after assembly, carefully straighten the aluminium feet; this often solves the problem.

Fit the transport wheels to the front of the machine.

The upright post of the cross trainer is secured with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

Inside the housing, near the flywheel, is a sensor that measures speed, just like a bike computer. A magnet is attached to the wheel spoke with the sensor close by. If the sensor is too far from the magnet, the speed can't be read and the display shows E1. Locate the sensor in the housing and slide it towards the magnet until it almost touches.

Were wave washers supplied with the machine? Fit them between the upright post and the arm.

First, lubricate all rotating parts with silicone spray. A squeak can also occur if a screw is too tight or too loose and causes friction. Find out where the sound is coming from and adjust that screw slightly. Screws should be tight enough that you can still loosen them by hand.

First, listen for the motor. When you increase or decrease the resistance, you should hear a short sound.

• If you hear the motor, the electronics are working and the V-belt has probably slipped off. Open the housing and put the V-belt back.
• If you don't hear the motor, the motor or display may be faulty. First check that the cable running through the tube is still properly connected. If it is, replace the display. If that doesn't solve it, replace the motor.

The flywheel inside the housing is probably hitting a cable with each movement. It's annoying but harmless. Open the housing and reposition the cable, or secure it with a cable tie.

Possible causes:

• The sensor cables to the display aren't properly connected or came loose during use.
• The sensors are damp, dirty or greasy. Clean them regularly.
• Calluses on your hands can interfere with the reading. In that case, use a chest strap.

Many rowing machines are assembled with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

First, listen for the motor turning inside the housing. When you increase or decrease the resistance, you should hear a short sound.

• If you hear the motor, the electronics are working and the V-belt (similar to a bicycle chain) has probably slipped off. Open the housing and put the V-belt back.
• If you don't hear the motor, the motor or display may be faulty. First check that the cable running through the tube is properly connected to the display and that the aluminium legs aren't bent. If the cables are fine and the problem persists, replace the display. If that doesn't solve it, replace the motor.

Connect the adapter to the front of the rowing machine. Don't plug it into a random port on the display.

Only use the adapter supplied with the machine. An adapter with a different voltage or amperage can cause damage.

Many indoor cycles are assembled with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

Inside the housing, near the flywheel, is a sensor that measures speed, just like a bike computer. A magnet is attached to the spoke with the sensor close by. If the sensor is too far from the magnet, the speed can't be read and the display shows E1. Locate the sensor in the housing and move it slightly closer to the magnet until it almost touches.

Resistance is controlled by one or two brake pads that press against the flywheel. If they aren't well lubricated, they can squeak as they rub against the wheel. Spray the brake pads with silicone spray to solve this.

Does your indoor cycle have a motor? First, listen for it turning. When you increase or decrease the resistance, you should hear a short sound.

• If you hear the motor, the electronics are working and the V-belt (similar to a bicycle chain) has probably slipped off. Open the housing and put the belt/chain back.
• If you don't hear the motor, the motor or display may be faulty. First check that the cable running through the tube is still properly connected. If it is, replace the display. If that doesn't solve it, replace the motor.

This is probably caused by one of the pedals. Remove the pedals and refit them. Note: tighten the left pedal anticlockwise and the right pedal clockwise. Tighten them firmly. If the noise persists, contact your supplier.

There's a battery on the back of the display. If the display stops working, replacing the battery often solves the problem.

If an indoor cycle with a V-belt slips, the belt isn't tight enough. You can tighten the belt in two ways:

• using the tensioner near the chain guard;
• if there's no tensioner: by pushing the flywheel forward, which increases the belt tension.

Carefully check the styrofoam and the machine itself. Some parts (bolts, screws and the like) may already be attached to or inside the machine.

Many home gyms are assembled with Allen bolts. Make sure the Allen key is fully inserted into the bolt before applying force. This prevents stripping the bolt head.

When fitting the cables from the weight stack to the pulley, make sure each cable runs properly over the pulley wheel. This applies to all cables. Fully unroll each cable before fitting it and straighten any curled cable first.
