Optimized Translation:

I. Poor contact at the battery terminal posts and oxidation of the contact surface significantly increase the probability of damage to excavator bucket teeth, computer board CPUs, and instruments. Similar to household appliances, if there is poor contact at the fuse box or switches, the light bulbs will flicker and are prone to burnout. The electrical system on excavators is similar to that of household appliances, so attention should be paid to ensuring reliable contact at the battery terminal posts.

II. Reversing the battery connections can cause severe malfunctions in the excavator bucket teeth, with a high damage rate. This can result in mild burnout of the fuse and severe burnout of the power circuits and CPUs of the computer panel and instruments. Some excavator wiring includes diodes, and reversing the positive and negative power connections will likely cause these diodes to burnout as well, making it an inevitable cause of failure.

III. Faults or abnormal operation of the accelerator motor. The accelerometer motors used in excavators include DC motors and stepper motors. If the motor overheats or shorts, it can easily burn out the control circuit of the computer panel throttle. This is an inevitable failure. Normally, attention should be paid to keeping the accelerometer motor assembly of the excavator clean to reduce the probability of faults occurring; when the excavator bucket teeth are powered on. When the excavator throttle motor linkage cannot be pulled, if force is used to move the throttle control lever, it may burn out the computer board of the excavator;
