Safety Guidelines
If you are a beginner ,it is recommended to finish the training courses ,or get assistance
from veteran before flying, and supervised by a veteran during the flight.
Do not disassemble any module or disconnect any plug when the power is on.
Please see that all parts and components are intact , and well installed and that
those aging or broken are replaced promptly before each flight. All devices should be
sufficiently charged. When the battery gets low during operation, you should return the
aircraft immediately and replace the battery.
For safety purposes, it is advisable to remove all propellers before each flight or after
firmware update until you have a test, inspect the remote control devices, motors and other
modules and ensure everything is in order.
Please charge the battery of the remote controller or aircraft when it falls to 20% to avoid
damage to the device caused by overdischarge of the battery stored at a low charge state
for a long time. By the same token, please keep the battery at 40%-60% when storing an
idle aircraft. The storage area should be dry, wellventilated and clean.
NEVER install/remove any module or insert/extract any circuit while the power is on.
Please ensure that the aircraft does not carry a load beyond the safe takeoff weight
specified in this User Manual. Overload, a safety hazard, is NEVER allowed.
Never take human bodies or animals, whether still or moving, or other hazardous objects
as obstacles in the obstacle avoidance experiment.
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.

4
Speed limit≤15m/s, distance limit≤1000m, it is recommended that the flight height be
2.5m~3.5m from the top of the plant, please operate correctly within the safety limit.
MOS smart battery is required.
Keep the product away from heat to prevent damage to the electronic component and
other parts or fire incidents.
For long-term storage or long-distance transportation, please remove the liquid tank from
the aircraft and empty it, and store the aircraft in a cool, dry place.
Recommended storage temperature (when the spray tank, flow meter, pumps, and hoses
are empty): between 10° and 40° C.
Pay attention to environmental protection when preparing and spraying pesticides. It is
prohibited to pollute rivers and drinking water sources.
Fly at locations that are clear of buildings and other obstacles. DO NOT fly above or near
large crowds.
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.

Introduction
Aircraft Features
The Z series agricultural UAV system solution is a full configuration solution provided by EFT. It
has two load models of 30kg and 50kg and is delivered in a semi-assembled form. It adopts truss
structure and Z-shaped folding arms to minimize the folding volume and facilitate transportation.
Equipped with double impeller pumps and water-cooled centrifugal nozzles , ultra-precision
sensor, ultrasonic flowmeter, integrated spreading system.
IP67 waterproof from inside to outside, sealed waterproof plugs and sealed core modules, which
can be washed directly. All parts can have closed-loop feedback by CAN protocol, early warning
of faults, smart Auto operation, effectively prolonging the lifespan of the drone.

Pre-flight Preparation
Inspection
Check whether the components are in good condition, especially the landing gear , the
internal flight control and flow meter interface etc..
Check the identification on the motors and propellers to ensure that the installation order is
correct (CW—M2/M4, CCW—M1/M3).
Check that all pins are not skewed and that the cables are properly connected.
Check whether the arm and cover is locked, and whether the nozzle is installed firmly.
After a overall inspection, level the motors, then unfold paddles and ready for testing.
Smart Battery
Installation
The smart battery can be installed directly, insert battery until hearing a clicking sound, then lock

9
the clasp.
Warning
Before installing the battery, please keep the interfaces at both ends clean, dry, no
metal debris and liquid residue.
Before starting the battery, please ensure that the battery is fully inserted to avoid
flight accidents during operation due to the battery not being tightly connected.
Make sure the battery power is off before inserting or removing the battery.
Power On
Short press the battery power button once, then press and hold it for over 2s, the 5 indicator
lights will flash in sequence, and you will hear two beeps, indicating that the aircraft is powered
on.Repeat the above steps to power off.

Signal Range
Unfold the antenna of the remote control and adjust it to a suitable position. The antenna
positions will affect signal strength. Adjust the external antenna forward to the aircraft for better
reception of signals. To ensure signal stability and flight safety, it is recommended that the
distance between the remote controller and the aircraft is not exceed 1000 meters.
Operating the Aircraft
The operation mode of the stick is recommended “American Hand”. This manual takes“American
Hand”as an example to introduce how to control the aircraft.

Remarks
Left Stick
Throttle Stick: Move the left stick vertically to
control the elevation of the aircraft.
Push up to ascend and push down to
descend. Use the left stick to take off when the
motors are spinning at an idle speed. The aircraft
hovers in place if the stick is in the center position.
The further the stick is pushed away from the
center position, the faster the aircraft changes
elevation.
Left Stick
Yaw Stick: Move the left stick horizontally to
control the heading of the aircraft.
Push left to rotate the aircraft counterclockwise
and push right to rotate clockwise. The aircraft
