1. Emergency stop lever: The manual engine stop lever

when emergency.

2. Upper control chamber: The cover is install for inside

control.

3. Electronic control chamber: The electronic signal oper-

ates the operation lever. It is sealed and can not

control.

4. Adjusting screw: Adjusting screw is the controlled

max. fuel capacity. If the length of the nut is long, the

torque is decrease. if the the length of the nut is short,

the torque is increase.

5. Fuel stop plate: The plate controls the increasing fuel

as the preventing movement of adjusting screw.

6. Operation lever: It is the connecting lever to operate

the fuel rack.

7. Fuel rack: It controls the fuel capacity of the fuel injec-

tion pump connected link lever.
