1 The wrecker boom is slow and incapable to stretch 1 hydraulic power system failure
2 telescopic mechanism control valve, overflow valve failure 1 inspection, adjustment
2 Disassemble, clean, adjust or replace damaged components
2 Wrecker boom extension stretching vibration 1 boom slider issue
2 telescopic cylinder is abnormal 1 Insufficient lubrication between the sliding surface of the boom box and the slider should be applied grease; slider surface deformation is too large, the slider should be replaced; the surface of the lifting arm should be damaged, the surface should be repaired
2 check processing
3 The length of the lifting boom of the wrecker cannot be compensated 1 solenoid valve failure
2 circuit failure 1 Clean the oil filter and replace the electromagnet
2Check the external line fault
