1) Before starting to use, a matching cable of 40-80 meters should be selected, one end of which is connected to the designated position of the loader control electric box (or explosion-proof magnetic starter), and the other end is connected to a three-phase AC power supply with leakage protection and the grounding resistance is less than 2Ω's ground grid.
2) Check the electrical: Check whether the voltage of the leakage circuit breaker is normal, whether the cable is in good condition, whether the terminal is loose and falling off, if there is any abnormality, it is forbidden to work, and the operation must be repaired immediately.
3) Control system: each control handle should be in the neutral position, the control should be flexible, and there should be no sticking phenomenon.
4) Check the hydraulic system: the connection between the hydraulic system components and their connecting pipelines should be tight without obvious leakage, the hydraulic pipeline should meet the regulations (the oil volume is greater than 4/5 of the total volume of the fuel tank), and the hydraulic oil must be kept Clean, it is not allowed to use dirty containers for storage, it must be added from the hydraulic air filter that is refueled, and when the oil level is insufficient, it must be replenished in time.
5) Check the conveyor system: the conveyor belt should be in good condition, without deviation, with proper tension, flexible rotation of idlers, and no abnormal sound.
