  * Users can set the action the aircraft will perform after the operation is completed in the app.

More Operation Modes and Functions

Refer to the user manual for more information about the A-B Route, Manual, Manual Plus, and Fruit Tree operation modes, and on how to use functions such as Connection Routing, Operation Resumption, System Data Protection, and Empty Tank.

Maintenance

Clean all parts of the aircraft and remote controller at the end of each day of spraying after the aircraft returns to a normal temperature. DO NOT clean the aircraft immediately after operations are completed.

• Fill the spray tank with clean water or soapy water and spray the water through the sprinklers until the tank is empty. Repeat the step twice more.
• Remove the spray tank strainer and sprinklers to clean them and clear any blockage. Afterwards, immerse them in clean water for 12 hours.
• Make sure that the aircraft structure is completely connected so that it can be washed directly with water. It is recommended to use a spray washer filled with water to clean the aircraft body and wipe with a soft brush or wet cloth before removing water residue with a dry cloth.
• If there is dust or pesticide liquid on the motors, propellers, or heat sinks, wipe them with a wet cloth before cleaning the remaining water residue with a dry cloth.
• Wipe the surface and screen of the remote controller with a clean wet cloth that has been wrung out with water.
  Refer to the disclaimer and safety guidelines for more information on product maintenance.

Fly Safe

It is important to understand some basic flight guidelines, both for your protection and for the safety of those around you.

1. Flying in Open Areas: pay attention to utility poles, power lines, and other obstacles. DO NOT fly near or above water, people, or animals.
2. Maintain Control at All Times: keep your hands on the remote controller and maintain control of the aircraft when it is in flight, even when using intelligent functions such as the Route and A-B Route operation modes and Smart Return to Home.
3. Maintain Line of Sight: maintain visual line of sight (VLOS) with your aircraft at all times and avoid flying behind buildings or other obstacles that may block your view.
4. Monitor Your Altitude: for the safety of manned aircraft and other air traffic, fly at an altitude lower than 100 m (328 ft) and in accordance with all local laws and regulations.
   Visit https://www.dji.com/flysafe for more information on critical safety features such as GEO zones.

Flying Considerations

1. DO NOT use the aircraft to spray in winds exceeding 6 m/s.
2. DO NOT use the aircraft in adverse weather conditions such as snow, fog, winds exceeding 6 m/s, or heavy rain exceeding 25 mm (0.98 in).
3. DO NOT fly more than 4.5 km (14,763 ft) above sea level.
4. The DJI Agras app will intelligently recommend the payload weight of the tank according to the current status and surroundings of the aircraft. When adding material to the tank, the max weight should not exceed the recommended value. Otherwise, the flight safety may be affected.
5. Make sure that there is a strong GNSS signal and the D-RTK antennas are unobstructed during operation.

Return to Home (RTH)

• The aircraft will automatically return to the Home Point in the following situations: Smart RTH: user presses and holds the RTH button.
• Failsafe RTH*: the remote controller signal is lost.
• Low Battery RTH*: the aircraft battery level reaches the preset low battery threshold.

The aircraft decelerates and then brakes and hovers if there is an obstacle within 20 m of the aircraft. The aircraft exits RTH and waits for further commands.

• The action of the aircraft when the remote controller signal is lost or the aircraft battery level is low can be set in the app. Failsafe RTH and Low Battery RTH will only be available if RTH is set.
• Obstacle avoidance is disabled in Attitude mode (which the aircraft enters in situations such as when the GNSS signal is weak) and is not available if the operating environment is not suitable for the radar modules or binocular vision system. Extra caution is required in such situations.

Pesticide Usage

1. Avoid the use of water-insoluble pesticides as much as possible as they may reduce the service life of the spraying system.
2. Pesticides are poisonous and pose serious risks to safety. Only use them in strict accordance with their specifications.
3. Use clean water to mix the pesticide and filter the mixed liquid before pouring into the spray tank to avoid blocking the strainer.
4. Effective use of pesticides depends on pesticide density, spray rate, spray distance, aircraft speed, wind speed, wind direction, temperature, and humidity. Consider all factors when using pesticides.
5. DO NOT compromise the safety of people, animals, or the environment during operation.

Aircraft

• The Agras T20P has a truss-style design with arms that can be folded to reduce the body size, making the aircraft easier to transport. The all-new integrated spraying system can quickly be swapped with a spreading system.
• The spatial intelligent sensing system includes active phased array radars and binocular vision to ensure flight safety. Boasting a 12MP UHD FPV camera with a tiltable gimbal, the aircraft can automatically collect HD field images for local offline reconstruction to assist in precise field planning. Using the P4 Multispectral and DJI Agras Intelligent Cloud, prescription maps can be generated in order to perform variable rate fertilization.
• The spraying system is equipped with the brand new magnetic drive impeller pumps, dual atomized sprinklers, and anti-drip centrifugal valves. When used with the weight sensors, the spraying system provides real-time liquid level detection and improves spraying efficiency while saving liquid pesticide.
• Core modules adopt potting technology and the aircraft has a protection rating of IPX6K (ISO 20653:2013) so that the aircraft body can be washed directly with water.
