Fault 2: It is difficult for the roller to move

Possible causes and solutions: (1) Hydraulic system failure: Check whether the hydraulic oil is sufficient, and if it is insufficient, add it in time; check whether there is hydraulic oil leakage, and if so, repair the seal at the oil leakage area. (2) Running wheel failure: Clean the debris around the running wheel to ensure that the wheel can rotate normally.

Fault 3: The road roller vibrates abnormally

Possible causes and solutions: (1) Vibration shaft failure: Check whether the vibration shaft is worn, broken or loose. If there is any problem, replace or repair it in time. (2) Insufficient hydraulic oil in the vibration system: Check whether the hydraulic oil in the lubrication system is sufficient. If it is insufficient, add more. (3) The vibration spring is damaged: Check the status of the vibration spring and replace it if it is damaged.

Fault 4: Roller brake is not working properly

Possible causes and solutions: (1) Brake failure: Check whether the oil circuit of the brake is smooth, and clean it if it is blocked; check whether the brake friction plate is worn, and replace it if it is worn. (2) Insufficient brake fluid: Check whether the amount of brake fluid is sufficient, and add it in time if it is insufficient.

Fault 5: Roller engine overheating

Possible causes and solutions: (1) Insufficient coolant: Check whether the amount of coolant is sufficient, and add it in time if it is insufficient. (2) Fan failure: Check whether the fan is operating normally. If not, repair or replace the fan.

The above is only a brief introduction to some common faults and solutions that may occur with second-hand rollers. Of course, different models and brands of rollers may have different faults and solutions.
