Four precautions for the operation of the hottest

Fourth, pay attention to the operation of plant protection UAV

pay attention to pesticide safety. When dispensing, please use clean water, otherwise it will cause the residue of liquid medicine to block the application pipeline. When charging, please pay attention to the splashing of liquid medicine. Aim at the mouth of the medicine box or the lead pipe to introduce the medicine, so as to prevent the splashed medicine from corroding the battery and motor. When using medicine, if there is residue blockage, please clean it in time before using it. Please pay attention to wearing protective equipment to prevent human body from directly contacting pesticides. When applying other drugs, try to avoid rivers and drinking water sources to avoid pollution

pay attention to operation safety. The flying hand's lack of common sense and instant fault are the biggest threats to flight safety. If the installation is not secure, the result will be very unsatisfactory. A loose screw will even vibrate and scatter the whole plant protection UAV. When flying, you should concentrate, not be half hearted, operate according to rules, do not taste at will, and can provide effective support. Try uncertain actions, and don't take it for granted to create aircraft instructions to avoid blowing up the aircraft

pay attention to battery safety. Please make sure to confirm the voltage of the battery pack before using the battery. The new battery should avoid large current charging, and pay attention to the battery temperature during use to avoid excessive discharge. When the battery is not used for a long time, it should be placed in a dry and cool place with a temperature of 0 ℃ ~40 ℃, and the battery should be fully charged and discharged once a month. Instead, it should focus on 'how will users who actually contact the material feel' to open up new uses. 'check the voltage of a single battery cell once a week

pay attention to environmental safety. Fly in an open area with an altitude of less than 2000 meters and away from people. Fly in an environment with a temperature of 0 ℃ ~40 ℃ and good weather. Avoid flying in windy, rainy and snowy weather. Keep away from people, trees, power lines, airports, tall buildings, signal towers and other high-risk buildings. Do not hover on the seedlings at low altitude to avoid damage to the seedlings
