72cc Post Hole Digger Earth Auger

The maintenance cycle and methods of the excavator are as follows:
1. Daily maintenance:
Cleaning: After each use, promptly clean the surface of the excavator and the engine of dust, soil, and oil stains, maintain the cleanliness of the heat sink, and avoid affecting the heat dissipation effect. • Inspection: Check the fuel and oil levels to ensure they are within a safe range; Check if the fasteners are loose and tighten them in a timely manner. Lubrication: According to the user manual, regularly add lubricating oil to rotating parts to reduce wear.
Regular maintenance:
Oil change: The oil is usually changed every 30 hours of use. For two-stroke engines, the mixed oil needs to be replaced regularly according to the oil mixing ratio.
• Fuel system: Regularly inspect and clean the fuel filter to prevent blockage; For a four stroke engine, the fuel filter and air filter should be replaced regularly.
Hydraulic oil:
If the excavator uses a hydraulic system, replace the hydraulic oil regularly according to the manufacturer's recommendations. Electrical system: Check electrical circuits and plugs to ensure no damage and good contact.
Blade and drill bit: Check if the blade or drill bit is worn or damaged, and replace or sharpen it if necessary.
Long term storage and maintenance:
Oil seal: If not used for a long time, the fuel in the tank should be drained to prevent the oil from deteriorating and damaging the engine. • Battery: For electric excavators, the battery should be fully charged and removed, stored in a dry and well ventilated place, and regularly charged to prevent battery aging.
Starting system: For manually started excavators, the starting rope can be pulled several times regularly to maintain the activity of the starting system. Professional maintenance:
Deep maintenance: After running for a certain number of hours (such as 100 hours, 300 hours, etc.), a comprehensive inspection should be carried out, which may include disassembly inspection, replacement of worn parts, adjustment of clearances, etc.
Troubleshooting: Once abnormal vibration, abnormal noise, or difficulty starting are found during operation, the machine should be immediately shut down for inspection and sent for repair if necessary to avoid causing greater damage.
The maintenance cycle and content may vary depending on factors such as the model, frequency of use, and working environment of the excavator. Therefore, the most important thing is to follow the specific guidance provided by the manufacturer in the user manual and regularly carry out maintenance to ensure that the excavator is always in the best working condition and extend its service life.
