User Manual
and can be cleaned using a small amount of water. The aerialelectronics system (barometer
excluded), spray control system, ESC system, and radar module has a protection rating of up to
IP67. However, this protection rating is not permanent and may reduce over time after long-term
use due to aging and wear. The product warranty does not cover water damage. The protection
ratings of the aircraft mentioned above may decrease in the following scenarios:
• There is a collision and the seal structure is deformed.
• The seal structure of the shell is cracked or damaged.
• The waterproof covers are not properly secured.
5. Operation
•
Stay away from the rotating propellers and motors.
•
The takeoff weight must not exceed 45.5 kg when using near sea level. Note that when using
at a higher sea level, the takeoff weight capacity will be reduced.
•
Once the operating altitude reaches 1 km (3,280 ft), the payload capacity of the spray tank is
reduced by 2 kg. For every additional km, the payload capacity will be reduced another 2 kg.
•
Maintain a visual line of sight (VLOS) of your aircraft at all times.
•
DO NOT use the Combination Stick Command (CSC) or other methods to stop the motors
when the aircraft is airborne unless in an emergency situation.
•
DO NOT answer incoming calls during ight. DO NOT y under the inuence of alcohol or drugs.
•
If there is a low battery warning, land the aircraft at a safe location.
•
If the radar module is unable to work properly in the operating environment, the aircraft will be
unable to avoid obstacles during Return to Home (RTH). All that can be adjusted is the ight
speed and altitude, as long as the remote controller is still connected.
•
After landing, stop the motors, power off the aircraft, and power off the remote controller.
Otherwise, the aircraft may enter Failsafe RTH automatically due to remote controller signal loss.
•
Maintain full control of the aircraft at all times and do not rely on the DJI Agras app. The
obstacle avoidance function is disabled in certain situations. Keep the aircraft within VLOS and
pay close attention to its ight. Use your discretion to operate the aircraft and manually avoid
obstacles in a timely manner. It is important to set an appropriate Failsafe and RTH altitude
before each ight.
6. Maintenance and Upkeep
•
DO NOT use aged, chipped, or broken propellers.
•
To avoid damaging the landing gear, remove or empty the spray tank during transportation or
when not in use.
•
Recommended storage temperature (when the spray tank, ow meter, pumps, and hoses are
empty): -20° to 40° C (-4° to 104° F).
•
Clean the aircraft immediately after spraying. Inspect the aircraft regularly. Refer to Product
Care in the Agras T20 Disclaimer and Safety Guidelines for more information about
maintenance guidelines.
7. Observe Local Laws and Regulations
•
You can find a list of DJI GEO zones at http://www.dji.com/flysafe. Note that the DJI GEO
zones are not a replacement for local government regulations or good judgment.
•
Avoid ying at altitudes above 30 m (98 ft).*
* In this document, the altitude limit of 30 m means the altitude between the aircraft and the surface of the objects below it
when the altitude stabilization function of the radar module is enabled. If the function is disabled, the altitude limit means
the altitude between the aircraft and the takeoff point.
The ying altitude limit varies in different countries or regions. Make sure to y at the altitudes outlined by local laws and regulations.
