Product attention


In order to ensure the safe operation of your excavator rotary motor gearbox and extend its service life, we provide you with the following precautions, hope that you can always stay alert during the operation and maintenance process to protect your investment and construction machinery.

Regular inspection and maintenance: Please check and maintain the excavator rotary motor reducer box regularly. Check whether the liquid level is sufficient, whether the lubricating oil is normal, and whether there is abnormal noise and leakage. Regular maintenance can detect potential problems early and avoid widespread failures and damage.
Use standard lubricating oil: Please use the appropriate lubricating oil recommended by the manufacturer, and replace it according to the specified service cycle. Suitable lubricating oil can ensure the normal lubrication of the gear and bearing inside the gearbox, reduce wear and friction, and improve the service life of the gearbox.
Avoid overload: Avoid exposing the excavator to an operating environment that exceeds its rated load. Long-term overload operation will increase the load of the gearbox, resulting in premature damage.
Smooth operation: When driving and operating the excavator, please keep it stable and avoid sudden braking and rapid acceleration. Frequent rapid movement increases the risk of wear and failure of the gearbox.
Prevent cold start: Avoid cold start at very low temperatures, it is recommended to preheat the engine in a cold environment to reduce the viscosity of hydraulic oil and lubricating oil and protect the reducer.
Pay attention to cleaning: In the working environment, please regularly clean the surface of the excavator rotary motor reducer box to prevent dust, mud or other impurities from entering the interior and affecting the normal operation.
Before stopping the excavator, please put the lever in neutral position before stopping the excavator, and then stop the excavator and pull the handbrake. Ensure that the vehicle stops working in a safe state.
Regular training of operators: Ensure that excavator operators are familiar with the relevant contents in the operation manual and safety manual to improve operation skills and safety awareness.
