Safety at a Glance
TM
The AGRAS T50/T25 aircraft is not a toy and is not
suitable for children under the age of 18.
Note that the Safety at a Glance section only provides a
quick overview of the safety tips. Make sure you read and
understand this document and the Agras T50/T25 User
Manual.
1. Pesticide Usage
• Avoid the use of powder pesticide as much as possible and
clean the spraying system after use. Otherwise, the service
life of the spraying system may be reduced.
• Pesticides are poisonous and pose serious risks to safety.
Only use them in strict accordance with their specifications.
• Residue on the equipment caused by splashes or spills when
pouring and mixing the pesticide can irritate your skin. Make
sure to clean the equipment after mixing.
• Use clean water to mix the pesticide and filter the mixed
liquid before pouring into the spray tank to avoid blocking the
strainer. Clear any blockage before using the equipment.
• Make sure to stay in an upwind area when spraying pesticide
to avoid bodily harm.
• Wear protective clothing to prevent direct body contact
with the pesticide. Rinse your hands and skin after handling
pesticides. Clean the aircraft and remote controller after
applying the pesticide.
• 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, but DO NOT compromise the safety of
people, animals, or the environment in doing so.
• DO NOT contaminate rivers and sources of drinking water.
• Disposal of surplus spray: Planning the spray operation helps
to ensure only enough pesticide for the area to be treated is
purchased and the amount of surplus spray solution is kept
to a minimum. It is recommended that any surplus spray or
washing liquid in the tank be applied to the crops. Users may
also consider installing a pipeline to handle the disposal of the
washing liquid in the tank.
• DO NOT use strong acids, strong bases, high-temperature
liquids, or pesticides that are explicitly prohibited.
2. Environmental Considerations
• Fly at locations that are clear of buildings and other obstacles.
DO NOT fly above or near large crowds.
• DO NOT fly over 4.5 km (14,763 ft) above sea level.
• Only fly in moderate weather conditions with temperatures
between 0° and 45° C (32° and 113° F).
• Make sure that your operations do not violate any applicable
laws or regulations, and that you have obtained all appropriate
prior authorizations. Consult the relevant government agency
or authority, or your lawyer before flight to ensure you comply
with all relevant laws and regulations.
• DO NOT operate any part of the aircraft indoors.
3. Pre-Flight Checklist
Make sure to check all of the following:
• Remote controller and aircraft batteries are fully charged.
• All parts are in good condition. Replace aged or broken parts
before flight.
• Landing gear and spray tank are firmly in place.
• Propellers and frame arms are unfolded and arm locks are
firmly tightened. Propellers are in good condition and firmly
tightened. There is nothing obstructing the motors and
propellers.
• The FPV camera and binocular vision system are clean and in
good condition.
• Spraying system is not blocked and works properly.
• Compass is calibrated after being prompted to do so in the app.
4. Ingress Protection Rating Description
Under stable laboratory conditions, the core modules of the aircraft
has a protection rating of IP67 (IEC 60529). 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.
2
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.
• Make sure to fly within the specified max takeoff weight to avoid
potential safety risks.
• The DJI Agras app will intelligently recommend the payload weight
limit for the tank according to the current status and surroundings
of the aircraft. DO NOT exceed the recommended payload
weight limit when adding material to the tank. Otherwise, the
flight safety may be affected.
• 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 flight. DO NOT fly under
the influence of alcohol or drugs.
• If there is a low battery warning, land the aircraft at a safe
location.
• If the radar modules and binocular vision system are 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 flight speed and altitude, as
long as the remote controller is still connected.
• After landing, stop the motors, power off the aircraft, and turn
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 flight. Use your discretion to operate
the aircraft and manually avoid obstacles in a timely manner.
It is important to set an appropriate Flight and RTH altitude
before each flight.
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, flow
meter, pumps, and hoses are empty): between -20° and 40° C
(-4° and 104° F).
• Clean the aircraft immediately after spraying. Inspect the
aircraft regularly. Refer to the Product Care section for more
information about maintenance guidelines.
7. Observe Local Laws and Regulations
• You can find a list of DJI TM
Note that the DJI GEO zones are not a replacement for local
government regulations or good judgment.
• Avoid flying at altitudes above 100 m (328 ft).*
* The flying altitude limit varies in different countries or regions. Make sure
to fly at the altitudes outlined by local laws and regulations.
