Inspect the Hit-Air to determine if there is any damaged prior to
wearing.
If there is any damage, consult with an authorized dealer.
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.
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.
The Neck Hit-Air is to be used for the rider’s safety when
riding a motorcycle and not for any other purpose.
The Neck Hit-Air of the right size is to be worn as an
outerwear on the upper half of the body.
Do not take any parts of the Hit-Air apart.
Remove sharp on pointed objects such as pins or pens from the
Neck 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 Neck 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℉

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 P13) may activate and inflate the Hit-Air.
Connect or disconnect the “one-touch release” while you are on the motorcycle.
4-4
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.
Once a gas cartridge is used, it cannot be used again. Buy a new one from an authorized
dealer.

Coiled Wire
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 . P13).
This causes the gas cartridge to release the CO2 gas into the air cushions to inflate them
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.
The Neck Hit Air (Shock–buffering Protection System) is to be worn as an outerwear
when riding a motorcycle.
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.
However, this does not imply or guarantee rider’s safety.

The Neck 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 Neck Hit-Air may not be repairable in some cases.
As soon as the “activation distance” is reached, the Hit-Air is activated and the CO2gas is
sent into the air cushions so that it will provide protection from the shock of impact even
before it is fully inflated.
The CO2gas cartridge and the “key box” area is covered by an ABS protector with buffer
material to protect the rider’s breast from the projecting objects in case of an accident.
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
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 maximum pressure is about 35kpa(0.25kg/㎠) when the air cushion is fully
inflated, but gradually decreases as gas comes out of the air cushion.
*1 Even if no damage is visible, there may be damages to the air cushion. Therefore, take
the Hit-Air to an authorized dealer for a maintenance check to test the air cushion for
leaks and inspect its parts to make sure it will function properly in case of an accident.
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 gas is sent from the “key box” to each air cushion through urethane tubing.
The Hit-Air is designed to act as a shock absorber and may break depending on the
shape of the object against which it strikes and also the extent of impact given.
Function
Air Cushion
To relieve a pressure, unfasten the front fastener and the
buckle and move both ends of the air cushion backwards.
After the airbag (air cushion) is inflated in full, the gas will leak out gradually.
Depending on the extent of the shock given to the airbag by the accident, a feeling of
tightness may be felt to start with, but gradually subsides. In case of difficulty in
breathing, remove the cap of the gas release valve (see illus.)
or take the Neck Airbag off to relieve a pressure.
*Some models have no gas release valve.

The “key ball” holds a compression spring and an
interlocking needle in the “key box”.
When the system is activated, the “key ball” comes
out of the “key box” and a needle in the “key box”
is released and punctures the seal of the gas cartridge
to inflate the Hit Air immediately.
The “key ball” and the “key ring” are integrated parts.
CO2Gas Cartridge
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.
6. Do not cut or puncture the gas cartridge.
8. Use the gas cartridge for the Hit-Air only, and not for any other purpose.
10. Keep the gas cartridges out of the reach of children.
12. Screw the CO2cartridge fully until it seats firmly in the key box but do not
over tighten.
9. Use a Hit-Air CO2gas cartridge only. Do not use any other one.
11. Once the gas cartridge is installed, don’t attempt to turn, loosen or remove it.
5. Confirm that the used gas cartridge is empty of gas before disposing.
4. Do not let corrosion form on the surface of the cartridge.
If corrosion is noticed, replace it immediately.
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.
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.
The gas cartridge contains CO2gas.
7. The size (capacity) of the gas cartridge varies from model to model.
Install the designated size (capacity) for the model.
Visit http://www.hit-air.com "Replacement Gas Cartridges list"
to find out the right size for the jacket.
Screw the CO2cartridge fully into the bottom until it cannot go any further.
Otherwise, a needle in the “key box” may not puncture the seal of the CO2cartridge
and Hit-Air may not be activated properly.

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

Protector tube
Protect a motorcycle and a coiled wire against damage.
Pass a coiled wire through a protector tube to protect the part of the wire wound round the
frame or handlebar etc. of the motorcycle. Cut the excess tube depending on the part where
the coiled wire is fixed.
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.

Pay attention when the Neck Hit-Air is inflated as follows.
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.
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
upset. 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.
When the Neck 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.
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 25).
Whether it has external damages(holes, scratches,tears etc.)
The Neck Hit-Air system is designed to protect the wearer’s neck, so
when it is inflated, there will be some pressure around
the neck. If there is any difficulty in releasing the
helmet’s chin-strap, unfasten the front fastener and the
buckle and move both sides of the air cushion
backwards (see illus.) to relieve a pressure.
