SAMPLE PAGES FROM THE MANUAL :

Major symptom is that overall movement is slow, the engine emits black smoke and often stalls under load.

Procedure 1：Replace one high-speed solenoid valve at a time and perform functional check. If the problem cannot be solved after replacement, reinstall the original part (after checking its resistance), and proceed with the next procedure. Since the high-speed solenoid valve may be damaged either electrically or mechanically (wear, breakage, etc.), do not judge the nature of failure by only checking for electrical performance. There has been an instance that an broken inner filter caused the machine to become slow in its movement after the engine was started but this symptom disappeared after about 5 minutes. The problem of this part falls under the wear-related failure mode and in many cases, this part eventually becomes short-circuited. Moreover, it is closely related to secondary damage to PVC and once occurred, this phenomenon will last.
Procedure 2：Replace the angle sensor and perform functional check. If the problem cannot be solved after replacement, reinstall the original part (after confirming that there is no short), then proceed with the next procedure. Since the angle sensor may be damaged either electrically or mechanically, do not judge the nature of failure by only checking for electrical performance. Be careful since the sensor failure depends on the temperature.
Procedure 3：Replace the pressure sensor and perform functional check. If the problem cannot be solved after replacement, reinstall the original sensor (after checking for resistance), then proceed with the next procedure. Since this sensor may be damaged either electrically or mechanically (broken diaphragm), do not judge the nature of the failure by only checking for electric performance. The problem of this part falls under the wear-related failure mode and once occurred, this phenomenon will last.
