Mini roller compactor failure causes and repair solutions

Image
  The mini roller compactor has the advantages of convenient operation, small size, light weight, suitable for compaction operations in narrow areas and places where large road rollers cannot be driven. It has been widely used, but due to factors such as large engineering workload and long working hours, When mini road roller is performing compaction work, it is inevitable that there will be some failures. If it is not solved in time, it will not only affect the work efficiency but also delay the construction period. Engine won't start Causes of failure: fuel exhaustion; fuel filter blockage; fuel pipe leakage; battery leakage or poor connection. Solution: Fill the fuel tank with fuel; replace the filter; check whether the battery is deficient, charge it in time if it is deficient, replace the battery with a new one, and check the circuit.
