Liugong mini excavators are versatile and compact machines that can be used for various tasks, from digging foundations to landscaping and demolition. These machines are designed to work in tight spaces and can easily manoeuvre around obstacles, making them ideal for construction sites, farms, and other work environments. They are known for their reliability, durability, and efficiency, but like any other machinery, they require regular maintenance to keep them running at peak performance. This article will discuss some vital maintenance considerations and tips for your Liugong mini excavator.

1. Regular Inspection and Maintenance:


Regular inspection and maintenance are essential to keep all Liugong excavators in good working condition. You should inspect your Liugong mini excavator before and after each use to ensure all components function correctly. Check the hydraulic hoses, fuel lines, and electrical systems for leaks, cracks, or other signs of wear and tear. Also, ensure the filters are clean and the oil levels are topped up.


In addition to daily inspections, it is essential to schedule regular maintenance services with a qualified technician. Liugong mini excavators have specific maintenance intervals, such as applying grease every 15 days, replacing the reducers after 520 hours of use, preheating the engine for a few minutes before use, and operating at a low speed for a little while before using the excavator normally – as outlined in a Liugong mini excavator owner’s manual. You should follow these guidelines to ensure your machine remains in good condition. During these services, the technician will inspect and replace worn-out components, check the hydraulic system, and perform other essential tasks to keep your Liugong mini excavator running smoothly. After 200 hours of work or once a month are a good rule of thumb.

2. Greasing and Lubrication:

Liugong mini excavators have many moving parts that require regular greasing and lubrication to prevent wear and tear. Grease the pins, bushings, and other pivot points at least once weekly to ensure they move smoothly. Also, lubricate the engine, hydraulic pump, and other components as the manufacturer recommends.

Using the proper grease and lubricant is essential to prevent damage to your Liugong mini excavator, such as Liugong Lithium Grease, or another Liugong genuine lubricant. Using the recommended grease and lubricant specified in the owner’s manual can ensure your machine operates at peak performance. Additionally, ensure you do not over-grease or over-lubricate, as this can cause damage to the machine.

3. Battery Maintenance:

The battery is a critical component of your Liugong mini excavator and must be adequately maintained to ensure reliable performance. Check the battery terminals regularly to make sure that they are clean and tight. Also, check the water level in the battery cells and top up with distilled water as needed.

It is essential to keep the battery charged to prevent damage. If the Liugong mini excavator will be out of use for an extended period, disconnect the battery to prevent it from draining. Additionally, ensure the battery is corrosion-free and the cables are securely attached.

4. Cleaning and Storage:


After each use, thoroughly cleaning your Liugong mini excavator is essential to prevent the buildup of dirt and debris. Use a high-pressure washer to remove dirt and grime from the machine’s exterior and clean the tracks and undercarriage. Also, make sure that the machine is stored in a dry and secure location to prevent damage from weather or theft.


When storing your Liugong mini excavator, turn off the engine and disconnect the battery. Also, cover the excavator to prevent dust and debris from accumulating.

5. Proper Use and Operation:

Proper use and operation are also essential to maintain your Liugong mini excavator. Ensure you use the Liugong mini excavator within its specified limits and avoid overloading or overworking the machine. Also, make sure that you operate the machine on stable ground and avoid operating near steep slopes or unstable terrain.

Additionally, follow the recommended operating procedures outlined in the owner’s manual. This includes starting and stopping the machine correctly, using the correct attachments, and operating it within its recommended speed range.

Liugong mini excavators are reliable and durable machines that can provide excellent performance for many years. However, following the recommended maintenance procedures and tips is essential to ensure that your machine operates at peak performance. Regular inspection and maintenance, greasing and lubrication, battery maintenance, cleaning and storage, and proper use and operation are critical to maintaining your Liugong mini excavator. Following these guidelines can keep your machine running smoothly and avoid costly repairs or downtime. Remember, a well-maintained Liugong mini excavator is a valuable asset that can help you complete your work quickly and efficiently, so ensure you take care of it properly.
