The jacket with the Hit-Air is to be used for the rider’s safety when riding a motorcycle and not for any other purpose.

The jacket with the Hit-Air of the right size is to be worn as an outerwear on the upper half of the body.

Use the gas cartridge of the same size and contents as before when replacing and confirm that there are no holes or tears in its seal.

Do not take any parts of the Hit-Air apart.

Remove sharp on pointed objects such as pins or pens from the jacket with the Hit-Air or from the underwear before wearing. They may damage the air cushion before or at the time of the activation and prevent the function of the Hit-Air.

Keep open flames and cigarettes away from the jacket with the Hit-Air as holes or tears caused by them will prevent its function. Keep and use at temperatures below as the gas cartridge may burst at a high temperature.

40℃/104℉

To make sure the Hit-Air will function properly, take it to an authorized dealer for a maintenance check, once a year depending on frequency of use.

Keep the Hit-Air by hanging up on a coat hanger. Do not fold or lay anything on it. Avoid high temperature and high humidity.

To avoid any damage to the airbag, do not prick a needle or sew emblems or iron on the jacket with the Hit-Air. Consult with an authorize dealer where to sew an emblem.

Make sure the “coiled wire” is securely attached to the motorcycle. Improperattaching may prevent the function of the Hit-Air.

Don’t wash or launder the Hit-Air /all-in-one airbag.

If a fray, rust on wear is found on the “wire loop” or the “coiled wire” attached to the “key ball”, replace it immediately.

Disconnect the Hit-Air from the “coiled wire” at the “one-touch release (connector)” before dismounting the motorcycle. Otherwise, it may cause an accidental activation.

Inspect the Hit-Air to determine if there is any damaged prior to wearing. If there is any damage, consult with an authorized dealer.

Coiled Wire

The jacket with the Hit-Air (Shock–buffering Protection System) is to be worn as an outerwear when riding a motorcycle.

It will be activated/inflated immediately after a distance from the rider to the motorcycle exceeds the “activation distance” (*1) when the rider falls off or thrown off the motorcycle. It will be activated at the moment the key ball is pulled out from the key box (see . P12). This causes the gas cartridge to release the CO immediately. Inflated air cushions are designed to come between the rider’s body and objects against which the rider may strike after falling off or being thrown off the motorcycle. The Hit-Air will act as a buffer to absorb the shock of impact and reduce the risk of injury the rider who wears it.

However, this does not imply or guarantee rider’s safety.

The key ball requires considerable strength to be pulled out and will not be released easily because of the elastic nature of the coiled wire , thus the Hit-Air will not inflate under normally anticipated riding conditions including standing on pegs.

(*1) The “activation distance” is defined as the length of the coiled wire stretched to its full length from the motorcycle to the rider’s key box on the Hit-Air without any obstacles in between.

If the “coiled wire” running from the “key box” to the motorcycle touches an obstacle such as the rider’s body, any part of the motorcycle, a whip or any other projecting object, there is a possibility of accidental activation within the “activation distance” by a force strong enough to pull the “key ball” out of the “key box”.

If the rider crashes or falls down together with the motorcycle, unless the “activation distance” is exceeded, the Hit-Air will not be activated. The Hit-Air will not protect areas where the inflated air cushion does not cover.

If the rider wearing the Hit-Air forgets to disconnect the “one-touch release” and goes away from the motorcycle farther than the “activation distance”, a force of approximately 30kg-35kg (see P12) may activate and inflate the Hit-Air. Connect or disconnect the “one-touch release” while you are on the motorcycle.

Once a gas cartridge is used, it cannot be used again. Buy a new one from an authorized dealer.

As soon as the “activation distance” is reached, the Hit-Air is activated and the CO2 gas is sent into the air cushions so that it will provide protection from the shock of impact even before it is fully inflated.

The CO buffer material to protect the rider’s breast from the projecting objects in case of an accident.

After the airbag is inflated in full, the gas will leak out gradually. Depending on the amount of the pressure given to the airbag by the accident, a feeling of tightness may be felt but gradually subsides.

The Hit-Air may not function properly, if there is a damage to the Hit-Air, cloth of the wear,, air cushion, Velcro, zipper, buckle etc. If so, consult with an authorized dealer. The Hit-Air may not be repairable in some cases.

Whenever the Hit-Air is inflated, even if there is no visible damage, we recommend taking the Hit-air to an authorized dealer for a maintenance check *1

Air Cushion

The air cushions are made of high quality strong urethane film to absorb and reduce the shock of impact as much as possible when they are swollen.

The maximum pressure is about 30kpa(0.3kg/㎠) when the air cushion is fully inflated, but gradually decreases as gas comes out of the air cushion.

The strength against breakage depends on the material of the jacket the material of the inner tube (urethane) and the strength of the stitch it also depends on the degree of impact, shape or hardness of the object the rider may hit after the Hit-Air inflates.

The gas is sent from the “key box” to each air cushion through urethane tubing.

Key Box

◯

With a tensile strength of approximately 30kg-35kg by the “coiled wire”, the “key ball” comes out of the “key box”. Then a needle in the “key box” is activated and punctures the seal of the gas cartridge to inflate the Hit-Air instantly. The “key ball” can be pulled out from any direction (Photo 1).

Do not take the “key box” apart or remove any parts.

Red slide cover

◯

Whenever using the Hit-Air, make sure the red slide cover is in the ‘unlocked’ (up) position. (Photo 2)

To re-assemble the key box, the red slide cover is to be used to confirm that the key ball is properly set in the hole of the key box. (Photo 3) If the key ball is not set in the hole properly, the red slide cover will not come down.

When the red slide cover is in the ‘locked’ (down) position, the “key ball” cannot be released from the “key box”, then the Hit-Air will not be activated. This may cause an injury to the rider in case of an accident. Whenever using the Hit-Air, make sure the red slide cover is in the ‘unlocked’ (up) position. (Photo 2)

Even if the red slide cover is in the ‘locked’ position, if the wire is pulled strongly, the “key box” may activate the Hit-Air to inflate. The Hit-Air may also inflate accidentally when the red slide cover is moved from the ‘locked’ position to the ‘unlocked’ position after the wire is pulled strongly.

CO2 Gas Cartridge

The gas cartridge contains CO

When the “key ball” is released from the “key box”, a needle punctures the seal of the gas cartridge to let the gas go into each air cushion.

Screw the CO2 cartridge fully into the bottom until it cannot go any further. Otherwise, a needle in the “key box” may not puncture the seal of the CO and Hit-Air may not be activated properly.

Do not reuse the gas cartridge once used. Change it to a new one. The seal at the bottom of an used cartridge is pierced with a hole.

1. Keep and use at the temperature below 40ºC/104°F. Do not keep in the car where the temperature may go up high.

2. Do not give the cartridge a strong shock.

3. Do not heat the cartridge.

4. Do not let corrosion form on the surface of the cartridge. If corrosion is noticed, replace it immediately.

5. Confirm that the used gas cartridge is empty of gas before disposing.

6. Do not cut or puncture the gas cartridge.

7. The size (capacity) of the gas cartridge varies from model to model. Install the designated size (capacity) for the model.

*Shape and how to use the “one-touch releas” may be different from the Photos 1 and 2.

Before riding the motorcycle, make sure the red slide cover on the “key box” is in the ‘unlocked (up)’ position (see page 12, photo 2).

If it is in the ‘locked (down)’ position, the Hit-Air will not work properly in case of accident etc.

Attaching Coiled Wire to Motorcycle

Where and how to attach the “coiled wire” to the motorcycle varies with the motorcycle. The rider’s movement when riding also varies. Taking these into consideration, decide the length of the “coiled wire” and the part of the motorcycle where it is to be attached (see page 17 to 18). Improper attaching may cause an accidental activation of the Hit-Air when the rider touches the “coiled wire” with some force.

Fix the “coiled wire” not in use on the part of the motorcycle, to avoid the “coiled wire” touching the heated engine etc., obstructing rider’s movement, coiling around the wheel and causing damages to it or the motorcycle. If such problem is foreseeable, remove the “coiled wire” from the motorcycle.

Due to the elastic nature of the “coiled wire”, the “key ball” or the “one-touch release” may hit the fuel tank or other part of the motorcycle causing damages when the Hit-Air is activated.

If the “coiled wire” is not attached to the motorcycle properly, it may come off when it is stretched then the Hit-Air will not be activated.

Replace the “coiled wire” when wear,burns,peeling or cracks are found.

*Do not use the coiled wire other than the one supplied by an authorized dealer.

Coiled Wire

Loop setter

After a coiled wire is fixed to a motorcycle and its length is adjusted, place it in the grooves of the loop setter and tighten the wing screw.

1. When getting on a motorcycle, confirm that the wing screw is tightly screwed down.

2. Place a coiled wire in the grooves of the loop setter and tighten it firmly with the wing screw. Leave more than 2cm of the wire outside of the loop setter, cut any excess wire and cap the cut end.

3. After the length of the wire is adjusted, tie a knot tightly. Otherwise, a wire may come off the loop setter and the airbag will not be activated.

Pay attention when the jacket with the Hit-Air is inflated as follows.

The jacket with Hit-Air is designed to provide protection especially to the wearer’s neck, so when it is inflated, there will be some pressure around the neck, and if it is difficult release the strap of helmet, take the Hit-Air off immediately.

Watching around the situation calmly, unzip and release the buckle to take off the jacket.

If the scene of accident seems to be dangerous, go to the safe area before taking off the jacket.

When the Hit-Air is inflated, a feeling of tightness may be felt, but the gas will leak out gradually. Therefore, calm yourself even if the body with the inflated jacket is pressed down by something.

If the air cushion is punctured when fully inflated, the gas in all the cushions will immediately escape and the cushions deflate.

If the Hit-Air inflates accidentally for some reason while riding, do not be alarmed. Look for a safe place and take an appropriate action. To continue to ride with the inflated Hit-Air may be dangerous due to the increasing wind resistance etc. Remove it first.

If there is an external damage to the Hit-Air due to its activation, take it to an authorized dealer for a maintenance check and to replace the gas cartridge. In cases of extreme damages externally or internally, it may not be repairable.

Be aware of the points listed below when attempting to re-assemble the Hit-Air by yourself after it is activated.

Whether it has external damages(holes, scratches,tears etc.)

Confirm that the airbag is fully inflated when it is activated.

Confirm that the gas cartridge to be replaced is the correct size and unused.

Go over the points listed above and if there are no problems, re-assemble the Hit-Air carefully at your own risk. It may not work as designed if there are external or internal damages. For further details for re-assembling see Chapter 7, (pages 20 to 24).

We recommend to take the Hit-Air once activated to an authorized dealer for a maintenance check and re-assembling. It can be reused if it is re-assembled in accordance with the following procedure, but unless it is done properly, it may not work. It cannot be re-assembled if it is damaged by the previous activation.
