After using a plant protection drone for medication, if the equipment is properly maintained and maintained, the usage rate of the equipment will become higher. To prolong the lifespan of plant protection drones, maintenance and upkeep are very important. The better the upkeep, the longer the lifespan of drones. Let's take a look at what needs to be done in the daily maintenance of drones.

（8）After completing each high-intensity task, it is necessary to use a slow charging and maintenance battery.
Maintenance of fuel filling
1. Daily maintenance and upkeep
Attention: All maintenance activities require the fuel charger (hereinafter referred to as the fuel charger) to be turned off and cooled to prevent high-temperature burns.
（1） Before each use, please check if the water tank has enough coolant or water.
（2） Please ensure that the cooling fan of the water tank operates normally every time you use it.
（3） Please check the oil condition every 8 hours of operation.
（4） When the oil indicator light is constantly on, it prompts us to add oil.
（5） When the oil indicator light flashes, it prompts us to change the oil.
2. Regular maintenance
（1）After the first cumulative operation of 20 hours, please change the oil. After every 60 cumulative operation hours, please change the oil.
（2） The air filter element needs to be cleaned every 100 hours of engine operation.
（3） It is necessary to regularly check the condition of the fuel pipes and replace them if they are found to be hardened or cracked. Check the fuel tank, fuel cap, carburetor, fuel switch, and other components that come into contact with gasoline. If there is any damage or leakage, it must be replaced in a timely manner.
3. Storage of fuel filling
