Safety At A Glance - DJI AGRAS T20 Manual Del Usuario

Safety at a Glance

The AGRAS TM T20 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 T20 User Manual.
1. Pesticide Usage
• Avoid the use of powder pesticides as much as possible as
they may reduce the service life of the spraying system.
• 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.
2. Environmental Considerations
• Fly at locations that are clear of buildings and other obstacles.
DO NOT fly above or near large crowds.
• The recommended maximum operating altitude is 2 km (6,560
ft) above sea level. DO NOT fly over 3 km (9,842 ft) above sea
level.
• Only fly in moderate weather conditions with temperatures
between 0° and 40° C (32° and 104° 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 sleeves
are firmly tightened. Propellers are in good condition and
firmly tightened. There is nothing obstructing the motors and
propellers.
• 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
The T20 is waterproof, dustproof, and corrosion-resistant when
it is functioning normally. Under stable laboratory conditions,
the aircraft has a protection rating of IPX6 (IEC standard 60529)
and can be cleaned using a small amount of water. The aerial-
electronics 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 47.5 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 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 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
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 Failsafe 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
flysafe. Note that the DJI GEO zones are not a replacement for
local government regulations or good judgment.
• Avoid flying 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 flying altitude limit varies in different countries or regions. Make sure
to fly at the altitudes outlined by local laws and regulations.
