Product operation method

Thank you for choosing our excavator rotary motor reducer products. In order to ensure that you can give full play to the performance and safe operation of the excavator, the following operation method guide is provided for you:

Pre-start inspection: Before operating the excavator, it is important to carry out a comprehensive inspection. Check whether the liquid level is sufficient, whether the lubricating oil is normal, and whether there are abnormal conditions in the reducer. Ensure that all levers, pedals and buttons are in working order.
Start the excavator: Follow the starting procedure in the operation manual to ensure that there is no abnormality during the starting process of the excavator. Please run without load for a period of time after starting to ensure that the lubricating oil of the reducer is in place to reduce the impact and wear during starting.
Operation order: When operating the excavator, always follow the correct operation order. First put the lever in neutral, then slowly adjust it to the desired speed. When changing gears, it is necessary to operate smoothly to avoid excessive load on the gearbox caused by sudden shift.
Acceleration and deceleration: When accelerating and decelerating, please keep steady and try to avoid sudden braking and rapid acceleration. Frequent rapid movement increases the risk of wear and failure of the gearbox.
Lubrication maintenance: excavator rotary motor reducer is a key component, maintaining adequate lubrication is very important. Please follow the cycle specified in the operating manual to replace and maintain the lubricating oil to extend the life of the reducer.
Avoid overload: When operating the excavator, avoid overload operation. According to the rated load and working conditions of the excavator, the operation should be reasonably adjusted to avoid unnecessary pressure and damage.
Regular inspection: check the working status of the gearbox regularly and handle any anomalies in time. If there are abnormal phenomena such as noise and oil leakage, please stop using immediately and contact professional maintenance personnel for maintenance.
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.
