The DJI Agras T40, since its launch at DJI AirWorks in Las Vegas in October 2022, has become the spraying drone of choice for both farmers and custom spray service providers, proving to be an indispensable asset for precision agriculture. For many T40 owners, we are about to begin our second season with the Agras T40 as our daily driver. Therefore, it’s essential for agricultural drone operators, farm managers, and custom spray drone service providers to perform preseason maintenance to ensure that their T40 is at the peak of its performance. Read on to see DJI Agriculture’s essential T40 preseason maintenance tips to start the 2024 spraying season on the right foot. Why a Preseason Checklist is Essential A preseason maintenance check is not just proactive; it’s a strategic move. The situation you want to avoid at all costs is arriving at the field, pressed by a tight schedule, only to find that your T40 has an issue that could compromise its performance or even sideline it for the day. Ensuring that your T40 and its components are in top condition before you hit the fields can prevent costly downtimes and potential accidents. By laying down a rigorous preseason checklist, you’re fortifying your agricultural operations against the uncertainties that come with technological devices that are exposed to the harsh conditions of the farming environment. Preseason Maintenance Checklist Here are some essential steps you can perform to make sure your T40 is ready for the season: Arms The arms of your T40 are its supporting pillars. They handle the drone’s weight and are critical for stability.   To start, open the arms up and lock them into place. If the arm glides from the closed to open position with little to no effort, this can be tightened with a 16 mm socket wrench   Next, verify that the arms are securely fastened. Grab each arm at the motor base and try to wiggle it. Loose arms are not just a flight risk; they can also throw off the drone’s calibration, affecting the precision of its spraying pattern. If an arm is loose, you will need a 16 mm socket wrench to tighten the nut.   This is a good time to also check the arm safety locks and make sure they are working correctly – when locking it you should hear it snap into place. If an arm lock is too loose, it can open by itself which is not good. Conversely, if the lock is too tight, it can be not only a hassle to lock/unlock it, but also potential cause for micro-fractures within the carbon fiber of the arms, which can lead to a larger fracture mid-flight. The locking handle tightness can be adjusted with a small 6 mm crescent wrench. With the handle open, there is a hex-shaped rod within the handle that can be adjusted with the wrench.   To finish the inspection of the arms, check for any surface damage. Even superficial cuts and abrasions can be weak points, potentially leading to failure in high-stress situations. Motors and Props Start by opening up the pair of props so they are close to 180 degrees, or a straight line. Notice the tightness of each prop and ensure the prop adapter screws have not become loose over time. These are really the only screws that need attention within this area.   Like the arm tightness above, there should be some resistance or tightness when opening the props – it shouldn’t glide open without any resistance.   After verifying prop tightness, glide your fingers along the edges of the props and ensure there aren’t and cracks, chips, or dents in the prop edges. If present, the props must be replaced prior to take-off. It’s important to note that props should be replaced in pairs, along with new prop gaskets.   Continue with a comprehensive visual inspection. Ensure all components, motors, and ESCs are in impeccable condition with no cracks, or chips. Follow up by checking all the screws, making certain they’re tightly fastened and secure.   After securing the components, take a moment to manually spin each motor. This is to detect any resistance or rough movement, which should be non-existent. Encountering difficulty while spinning the motors could point to a potential issue. Should such a resistance or roughness occur, it’s normally caused by coil corrosion, broken bearing or other damages in the motor. Please contact your dealer to have further check. Spraying System Preseason is a great time to recalibrate the spraying system. This includes recalibrating all the weight sensors, pumps, and flow meters. On DJI AGRAS App, go into the drone’s Spraying System Settings, add a liter of water into the spraying tank, click ‘Clear Trapped Air’ first to clear trapped air from the sprayer pump hoses, and then do Flow Meter Calibration. Empty the tank, then go into ‘Weight Sensors’ in Spraying System Settings, click ‘Tare Calibration’ to reset the weight display to 0. Then fill your tank with 20 L water, and check whether the payload weight displayed on the upper-right corner is between 16-24L. If so, do Weight Calibration. Lastly, turn on the sprinklers and make sure it can reach its max flow rate, which should be 12 L/min (3.1 gal/min). At the same time, check if there’s any leaks. Batteries and Chargers Without a doubt, optimal battery performance, including fast charging, can make or break your operation efficiency. Preseason is a great time to ensure your batteries can fast charge. Inspect the charging ports of each battery and make sure there’s no corrosion or damage, such as green-tinged rust covering the pin.   This is a good time to mention that any dust, dirt, or debris can be cleaned off from the battery ports and the battery pins of the drone using a 95% alcohol solution and a cotton swab or microfiber towel. This kind of cleaning should be checked and done daily to help extend the life of the battery and…
