To ensure maximum safety, the helmet should fit perfectly and feel comfortable. This means that it should not be either too tight, because it would be impossible to wear it for long periods of time, or too large, because it would not provide enough protection in the case of impact, or it could slip to the side or off your head while driving.

1. To determine the correct helmet size, the first thing to do is to measure your head by passing a tape measure around it a couple of centimeters above the eyebrows and ears.

2. Based on the helmet size that you have just determined, now you must try it on to make sure that it fits properly and feels comfortable. Pull both parts of the chinstrap to the side (see figure) and put on the helmet, sliding it from the back of the head to the front.

3. At this point, make sure that all the liner parts (sides, top, front) adhere to your cheeks, the top of your head and forehead. Keep your head still and try to turn the helmet slightly to the right and left, then move it up and down and backward and forward (see figure).

The helmet adheres properly if it pulls the skin on the cheeks and forehead, so if it turns too easily around your head it is too big and you should try a smaller size.

4. The last step is to fasten the chinstrap as tightly as possible but without hurting and with your head bent forward, try to remove the helmet by pulling it from the back to the front (see figure).

If the helmet comes off easily, it is not the right fit for you.

5. If the size seems to be right, keep the helmet on for a few minutes to make sure that it does not hurt or there are no pressure areas. If you are not sure, repeat the steps above until you find the helmet that fits the best. Always choose the smaller size if you are undecided between two different size helmets that both feel comfortable

Always remember to put on and fasten your helmet correctly. Never wear a scarf under the retention system or a hat under the helmet. The helmet should be put on and adjusted while the vehicle is not moving.

Periodically check the condition of the helmet and its components that are subject to wear (screws, mechanisms, buttons, plastic parts, etc.), particularly the following:

- The surface of the helmet, to make sure that there are no cracks;

- The chinstrap, to make sure that it is in good condition and that the retention system works correctly;

- The lining and buttons/attachments to the helmet, to make sure that they are in good condition;

- The visor, to make sure that it is not scratched and that you have perfect visibility;

- The visor mechanism, to make sure that it works correctly.

Bear in mind that wearing a helmet may deaden the sound of traffic and the surrounding environment, particularly if it is an integral helmet. Make sure that you can still hear sounds such as horns and emergency sirens, and correctly evaluate the impact of the helmet on your perception of external conditions.

Be prepared for sudden changes in the weather conditions that may occur while you are driving and which may influence the performance of the helmet (e.g. fogging of the visor due to a drop in temperature or rain, low visibility while driving through tunnels, etc.).

The helmet must always be handled and treated carefully so that its safety features remain intact.

Use the special all-purpose AGV cleaner to clean the shell and liner of the helmet, or alternatively use a soft cloth with neutral soap and warm water to wipe the outside of the helmet and non-removable liners. Rinse it by wiping it with a soft, wet cloth.

Removable liners can be washed by hand or in the washing machine using warm water (max 35°) and neutral soap. Always air dry the liner without exposing it to sources of heat. Make sure that the liner is completely dry before using the helmet again to prevent mould and unpleasant odours.

Do not use gasoline, benzene or other chemical products and solvents because they may jeopardize the functioning and structure of some of the parts and weaken the protective features.

We strongly advise against painting the helmet for the same reason, because paint solvents may damage the materials of the helmet.

Never modify the helmet (for example, drilling holes or cutting the shell, pressing the polystyrene, cutting the retention system or the liner) to avoid weakening the structure and jeopardizing the protective features. Always use original AGV parts if you need to replace a part and contact an AGV dealer if you are not sure how to perform an operation.

Avoid conduct or uses of the helmet that might compromise its performance:

- Do not drive with the helmet hanging from the anti-theft device/helmet hook or the seat so that it does not become bumped or scratched.

- Do not place the helmet on the stem of the rear-view mirror or the back of the seat so that the liner does not become damaged.

- Do not sit on the helmet or place it on the ground.

- Do not leave the helmet on places such as the gas tank or the seat because it could easily fall and become damaged. For the same reason, keep the helmet away from children and animals, which may cause it to fall, scratch it or ruin it.

- Never remove the structural parts of the helmet, such as the inner shell, the strap or the seals.

- Do not expose the helmet to very bright sunlight.

NB The Fluo colours are very delicate and sensitive to light: AGV does not guarantee the quality of the Fluo colours over time.

Always keep the visor in excellent condition to ensure perfect visibility. Replace it immediately if it becomes scratched, damaged or can no longer be cleaned properly.

In order to clean the visor properly, remove it from the helmet and wipe it with a soft cloth and the special AGV cleaner.

Alternatively, wipe the visor with a soft cloth and warm water, adding neutral soap to the water if the visor is very dirty. Rinse it under running water and dry it with a soft cloth. It is much easier and you will obtain the best results if you clean the visor and helmet immediately after use.

- Do not use gasoline, benzene, glass cleaners or other chemical products and solvents because they may jeopardize the quality of the visor

- Do not use sources of heat to dry the visor

- Do not use sharp or pointed objects to remove dirt from the visor so that it does not become scratched

- Do not apply stickers or sticky tape to the visor

Follow the instructions above to clean the plastic parts of the helmet such as the air inlets and visor mechanism. Use compressed air to remove dirt, dust or insects from the parts that you cannot reach with a cloth. Remove the lining or cover it with newspaper to protect it and prevent the inside of the helmet from becoming dirty during this operation.
