Key Box
The "key ball" comes out from the "key box" when it
was pulled by a certain tensile force.
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.
Do not take the "key box" apart or remove
any parts.

Key Ball

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.

Hit-Air CO2 gas cartridge

The Hit-Air CO2 gas cartridge contains CO2 gas.
When the "key ball" is released from the "key box", a needle punctures the seal of the CO2
gas cartridge to let the gas go into each air cushion.
Screw the Hit-Air CO2 gas 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 Hit-Air CO2 gas
cartridge and Hit-Air may not be activated properly.
Do not reuse the Hit-Air CO2 gas cartridge once used. Change it to a new one.
The seal at the bottom of a used cartridge is pierced with a hole.
Observe the followings to avoid a burst
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.
Visit https://www.hit-air.com/
"List of replacement gas cartridge size" to find out the right size for your Hit-Air.
8. Use the gas cartridge for the Hit-Air only, and not for any other purpose.
9. Use a Hit-Air CO2 gas cartridge only. Do not use any other one.
10. Keep the gas cartridges out of the reach of children.
11. Screw the Hit-Air CO2 gas cartridge fully until it seats firmly in the key box but do not over tighten.

Function and Structure
1.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
Back
shock of impact even before it is fully inflated.
2.The Hit-Air CO2 gas 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.
3.After the airbag 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.
4.The Hit-Air may not function properly if there is a damage on the Hit-Air,
CAUTION
fabric part, air cushion, Velcro, zipper, buckle or other parts. If there is any
damage or deterioration on any part, consult with an authorized dealer. The
Hit-Air may not be repairable in some cases.
5.Whenever the Hit-Air inflated, even if there is no visible damage, we recommend

*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 if it will function properly in case of an accident.
