safety memory unit before handling with the steering system. In order to
remove or install the airbag components, please disconnect the negative grid
of the battery and wait for at least 1 minute.
Removal/Installation
The hairspring is installed between the steering wheel and the steering column. When
installing the hairspring, pay attention to the installing position and direction, otherwise it
would cause insufficient turning angle or heavy rotation of the steering wheel.
In order to remove and install the hairspring, it is necessary to check the hairspring clearance
during rotating.
Warning: In order to check the clearance, turn the hairspring carefully until we can feel the
resistance. After that turn back for about 4 cycles and align it with the clearance marking.

4. AIRBAG COMPONENTS
(1) Airbag components
The airbag components consist of the airbag decoration cover, airbag and inflating
components. The airbag is made of nylon fabric. The internal layer was treated with synthetic
glue for sealing air. When the airbag is not open, it is folded like a bag of the unopened
parachute and installed between the upper part of air inflator and the airbag cover. There is a
impression line for tearing on the surface of the airbag decoration cover so that the decoration
cover can be torn off easily during the inflation of the airbag and reduce its resistance to let
the airbag passes through.
When the vehicle is collided, normally the airbag will start to inflate within 10ms after the
first collision, and the total inflation time from the starting of inflation through the entirely
activation of the airbag is about 30mS. When the airbag is activated, it spreads out along the
steering column to the direction of the windshield and thus prevents the driver’s face to
collide with the windshield, and his chest to collide with the steering wheel.
There is an air discharging hole at the back of airbag (opposite to the driver). When the driver
