DJI Agras T100/T70 Series/T25P Preflight & Operating Environment Safety Checklist
The safety guideline's preflight and environment sections are dense enough that they are more useful as a visual checklist than as one long warning block. This page turns them into a field sequence: power → hardware → spraying system → crew → app → weather → GNSS → altitude.
Quick Answer: Fully charge all devices, use genuine components, inspect propulsion/sensors/antennas, secure the battery, spray tank and arm locks, confirm the spraying system has no blockage or leaks, clear the work area, verify DJI Agras and all warning messages, wear a helmet and stay more than 6 m from the aircraft. Operate from 0-40°C, do not fly in winds above 6 m/s, heavy rain above 25 mm in 12 hours, snow, ice, fog or lightning, maintain more than 10 m from crowds and animals, use strong GNSS in open areas, and do not fly above 4.5 km above sea level.
Power and component condition
All devices should be fully charged. DJI says to use genuine components and to confirm that motors, propellers, the vision system, radar module and antennas are in good condition and not blocked by foreign objects. Aged or broken parts should be replaced before flight.
Secure mounting and cable connections
The aircraft battery, spray tank, arm locks and related cables must be mounted and connected correctly and firmly. The broader aircraft should be damage-free and functioning normally, including the remote controller, compass, propulsion system, radar module and payload system.
Spraying-system readiness
DJI says the spraying system must not be blocked or leaking and that the sprinklers must work properly. This is an operational safety check, not just a maintenance note.
Helmet, 6 m aircraft clearance and debris control
The source says to always wear a helmet during operation and maintain a safe distance of more than 6 m from the aircraft. Keep other personnel, vehicles and obstacles clear. Remove loose debris such as plastic bags, empty fertilizer bags and plastic film that can be blown into the aircraft.
Verify DJI Agras and warning messages
Make sure the app is functioning properly and examine all warning messages on the aircraft status list before every flight. The source also notes that DJI Agras flight data stored on the remote controller can matter for after-sales support in some situations.
Weather limits
Operate only in moderate weather from 0°C to 40°C. Do not use the aircraft in winds exceeding 6 m/s, heavy rain above 25 mm in 12 hours, snow, ice, fog or lightning.
Spray drift
For spraying, DJI says to operate below 6 m/s wind. It recommends below 3 m/s when using herbicides, fungicides or insecticides that drift easily and pose phytotoxic risks.
Separation from people and obstacles
During takeoff, landing and flight, stay away from roads, water surfaces, utility poles, high-voltage lines, trees and similar obstacles. Maintain more than 10 m from crowds and animals.
GNSS, electromagnetism and open areas
Operate only with a strong GNSS signal. DJI specifically identifies indoor environments and areas under bridges as examples where GNSS may be severely affected. Fly in open areas and avoid strong electromagnetic environments such as mobile-phone base stations and radio transmission towers.
Altitude and low-temperature payload reduction
Do not fly above 4.5 km (14,763 ft) above sea level. DJI says payload capability decreases as altitude rises and warns that battery and aircraft performance can be reduced at 2 km (6,560 ft) or more. In low-temperature environments, fully charge the flight battery and reduce payload.
