Safety at a Glance
1. Pesticide Usage
• Pesticides are poisonous and can pose serious risks
to human safety. Use them in strict accordance with
their specications.
• Residue on the equipment caused by splashes or
spills when pouring and mixing the pesticide can
irritate your skin. Be sure to clean the equipment after
Note that ‘Safety at a Glance’ only
provides a quick overview of the
safety tips. Make sure you read and
understand the remaining sections of
this document.

only.
mixing.
• Use clean water to mix the pesticide to avoid blocking
the strainer. Clear any blockages before using the equipment.
• Wear protective clothing to prevent direct body contact with the pesticide. Always rinse
your hands and skin after handling pesticides. Clean the aircraft and remote controller after
applying the pesticide.
• Effective use of pesticides relies on pesticide density, spray rate, spray distance, aircraft
speed, wind speed and wind direction. Consider all factors when using pesticides, but NEVER
compromise the safety of people, animals and the environment in doing so.
• DO NOT contaminate rivers and sources of drinking water.
2. Environmental Considerations
• Always y at locations that are clear of building and other obstacles.
• DO NOT y above or near large crowds.
• Avoid ying at altitudes above 50 m.
• Be very careful when ying over 2,000 m above sea level.
• Fly in moderate weather conditions with temperatures between 0° to 40° C.
3. Pre-ight Checklist
• Remote controller and aircraft batteries are fully charged.
• Landing gear and spray tank are rmly in place.
• All screws are rmly tightened.
• Propellers and frame arms are unfolded, and arm sleeves are rmly tightened.
• Propellers are in good condition and rmly tightened.
• There is nothing obstructing the motors.
• Spraying system is without any blockage and works properly.
• Compass is calibrated at every new ight location.
4. Operation
• Stay away from the rotating propellers and motors.
• The takeoff weight must not exceed 24.5 kg (taking off at sea level).
• Maintain line of sight of your aircraft at all times.
•
NEVERstopthemotorsmid-ight.
• DO NOT answer incoming calls during ight.
• DO NOT y under the inuence of alcohols or drugs.
• During the Return-to-Home procedure, you can adjust the altitude to avoid obstacles.
• In the instance of a Low Battery Warning, land the aircraft at a safe location.
• Always keep your hands on the remote controller so long as the motor is still spinning. Power
off the aircraft before turning off the remote controller after landing.

5. Maintenance and Upkeep
• DO NOT use aged, chipped or broken propellers.
• Remove or empty the spray tank during transportation or when not in use to avoid damaging
the landing gear.
• Recommended storage temperature (empty spray tank): between -20° and 40° C.
• Clean the aircraft immediately after spraying.
• Inspect the aircraft every 100 ights or after ying for over 20 hours.
• For more maintenance guidelines, refer to the Product Care section in Disclaimer and Safety
Guidelines.
6. Observe Local Laws and Regulations
• DO NOT y in the No Fly Zones. You can nd a complete list of these areas at
http://www.dji.com/y-safe/category-mc
• The DJI No Fly Zone is not a replacement for local government regulations or good judgment.
• Avoid ying in areas where rescue teams are actively using the airspace.

Introduction
The Agras MG-1 (abbreviated as MG-1) is a battery-powered multirotor aircraft designed for
agricultural applications in variety of environments and terrains, including terraces, elds, forests
and orchards. It is dust-proof, water-proof (IP43 protection rating, IEC standard 60529) and made
of anti-corrosive materials, allowing it to be rinsed clean.
The MG-1 also includes DJI’s industry-leading flight control system and three useful Operation
Modes: Smart, Manual and Manual Plus. A microwave radar underneath the aircraft makes the
MG-1 uniquely versatile across different terrains and the combined Altitude Stabilization System
automatically maintains the aircraft’s height above plants to ensure optimal spraying.
The remote controller features a Spraying Status Panel decorated with intuitive icons and a range of
controls for navigation, mode and spraying. While the MG-1 does all the hard work in the elds, you
keep full control over it in the palm of your hands.

Feature Highlights
The MG-1 provides three useful Operation Modes: Smart, Manual and Manual Plus.
In Smart Operation Mode, the aircraft will travel along a pre-planned route and spray liquid payload.
Users can set the operation gap, ying speed and other parameters. The MG-1 can cover an area of 7-10
acres per hour.
In Manual Operation Mode, users can start and stop spraying manually and also adjust the spray rate.
In Manual Plus Operation Mode, the flying speed is restricted and the aircraft’s heading is locked.
Except for the heading, users can control the movement of the aircraft.
The MG-1 also includes two intelligent memory features: operation resumption and system data
protection. When the operation mode is changed from Smart Operation Mode, operation resumption
records a set point for the aircraft to return to when Smart Operation Mode is reinstated. System data
protection keeps the system data for a period of time even when powered off so users can resume their
missions after replacing the battery.
The spraying system includes a spray tank, sprinklers and other accessories. The four sprinklers placed
on the aircraft’s two sides provide well-distributed spraying and great coverage. The nozzles on the
Agras MG-1 can also be swapped out to meet the needs of different applications.

Installation
Threadlocker is required for installation. Apply threadlocker when mounting landing gear,
spray tank, sprinklers and radar module. Ensure threadlocker is totally dry and solid
before ight.
Ensure that all installation and connection procedures are completed before powering on
the aircraft.
Mounting the Landing Gear
(For the right landing gear leg only)
The structures of the two landing gear legs are different. The one with a compass cable
should be mounted to the right side of the aircraft (when looking from the rear).
1. Identify the landing gear leg containing the compass cable.
2. Take out the cable protector from the landing gear leg and open it. Looking from the rear,
connect the compass cable to the compass port on the right side of the aircraft body. Put the
assembled cable into the cable protector slot and close it. Be careful not to damage the cable.
3. Place the cable protector and cable into the mounting position on the center frame then mount
the right landing gear leg to the mounting position and tighten the M3×10 screws.
