### To ensure that your aircraft continues to offer optimal performance and to ensure flight safety, it is recommended that comprehensive maintenance be performed after every 200 flights or 50 flight hours. This manual is intend to help users maintain their aircraft and maximize its continued reliability.

I. CheckingtheBattery

1. Check the battery for damage and deformities. If

there are any signs of damage to the battery, stop using it and discharge the battery to 10% or below 

### tordisposal. Do not disassemble the battery for any reason. 2. Check the battery pins and rub them clean with an

eraser if any residue is observed. This will help to ensure amore reliable connection. 3. Check the metal battery power connectors for

damage. If the connectors appear burnt, try to clear them. This can be done by inserting a piece of sandpaper (1mm thick) into the connectors to polish the metal. 4. Checkthe contact pins in the battery compartmentto

ensure that the pins are clear. They should be able to establish easy contact with the battery connectors and should notbe bent 5. Check the electrodes on the battery. If they appear

burnt, polish them with sandpaper. If there is serious erosion, send the battery in for repairs. 6. Check the plastic components of the battery bracket

to see it is in good condition and that all screws are secure. This prevents the battery from becoming loose duringflight. 7. Check the power cables between the arms and the

center plate, if the cables are worn, contact OJI to arrange repairs. 8. For long term storage, please refer to the "Intelligent

Flight Battery Safety Guidelines" and check the battery once a month to prevent the battery cell from beingdamaged. 9. Run the DJI Pilot App to confirm that all battery cells

are atsimilarvoltage levels and stay atthe same level when the battery is fully charged. If all cells maintain voltage levels above 3.7V but any cell is 0.2V higher or lowerthan the others, contact OJI for analysis. You can also checkthe battery cell warning history. If any warning are reported, contact DJI. II. CheckingtheTransformationSystem 1. Check the servomotor cables for wear. Also confirm

thatthe connection points are still in good condition. 2. Check the lead screws and contact DJI Support

to arrange repairs if any bending or damage is discovered. Clean the lead screws with WD-40 spray ifthey showsignsof rust. 3. Listen to the servomotors during the transformation,

if there is abnormal noise, it may indicate that the servomotorsworn. 4. After the landing gear rises, check the lead screws

and bearings. If any dirt or dust is found, clean and greasethe bearings. 5. Check the lead screws. If there is any scratches,

dents, or plastic particles underneath them, contact DJI Supportto arrange repairs.

Ill. CheckingtheAircraft 1. Confirm that all the screws are still adequately

tightened. 2. Check the aircraft for breaks or damage. Ifthere is

any reason to believethatdetectabledamage might affectflightsafety, consuitwith DJi Support. 3. Checkthe carbon tubes ofthe armsfordamage. 4. Checkthe damperson the landing gears. Iftheyare

loose, securethem with 502 glue. 5. Ensure that there are no obstacles on or around the

GPS moduleoraround the antennas on the landing gear. Remove any obstacles (such as tapes with conductive material) that might affect or block the signal. 6. Checkthatthe right and left landing gear rest atthe

sametilt angle.IV. Checkingthe Motors 

### 1. Check the rotors to confirm that they have not

become loose. 

### 2 Detach the propellers and start the motors. Listen

carefully. If there is any abnormal noise, please replace the motors. This may be a sign that the bearings have been worn out. 3. Detachthe propellers and startthe motors. Carefully

examine the edge of the rotor and confirm that the shaft is perfectly centered on the motor. Check for any abnormal or excessive vibration. If any problems are detected, contact DJISupportto order replacement motors. 4. Check for deformities by confirming that the gap

between the motor and motor base is even. If not contact DJI Supportto order replacement motors. 

### 5. Ensure that the screws used to secure the motor

base are tight and the plastic components around the motors are in good condition. If not please tighten the screws and contact DJI to repair any broken plastic components.

V. Checkingthe Propellers

1. Check the propellers. If there is any bending,

breakage orcracking on a propeller, do not use it. 2. Attach the propellerto the motor, turn on the aircraft,

and place iton the ground. Stand 1meteraway from the aircraftand observethe rotating propellers. Ifyou can see two distinct propeller outline layers, when looking at a spinning propeller from the side, this propeller is damagedand should notbe used.

VI. CheckingtheIMU 1. Open DJI Pilotappto checkthe condition ofthe IMU

and perform an advanced IMU calibration. Please place the aircraft in a cool environment and on a flat, stable surface (if the landing gear is damaged, support the aircraft with four objects of equal height). Do nottouch the craftduringthe calibration. 2. Turn on the aircraftand listen for any abnormal noise

or vibration from the fan located on the front of the aircraft. If any irregularity is detected, replace the fan.

VII. CheckingtheControland VideoTransmissionSystem Checkthe4antennas onthe landing gearto ensure thatthey are secure. Also checkfor any bending or damage. 2. Check the antennas of the remote controller for

damage 3. Check the neck strap for damage or wear, replace

if necessary. VIII. CheckingtheGimbalandCamera 

### 1. The quick-mount connector for the camera is a

particularly vulnerable component. If the gimbal fails to initializewhen turned on, fails to work after initialization, or fails to transmit video to the app (while OSD data is displayed), the quick-mount connector may be worn. In this case, replace the rubber mat, circuit board, and/or connector on the gimbalquick-mount. 2. Check the metal contacts on the quick mount

connector board, if any contact is bent, replace the quick-mountconnector. 3. Check the contact pins on the quick-mount

connector board, if there is any dirt, rub it clean with an eraser. If any contact pins are worn out it should be replaced. 4. Confirm thatthe gimbal is able to properly stabilize

itself. If its stabilizing performance deteriorates, contact DJI to arrange repairs. 

### 5. Listen for any abnormal noise from the fan when

the gimbal is turned on. This may indicate unusual vibration and the fan should be replaced.

IX. CheckingtheVision Positioning System 1. Check the lens of the camera. If any dirt or residue

is detected, gently clean the lens. 2. Check for and remove objects that might block the

sensors. 3. Ensure thattheVision Positioning System is securely installed onthe aircraft. 4. Detach the propellers and turn on the aircraft. Hold

the aircraft 1-2 meters above a surface with rich patterns, under good lighting conditions. Change the Flight Mode switch to P Mode on the controller and check the DJI Pilot app. If the app displays an altitude value and indicates that P-OPTI mode is active, theVision Positioning System should function normally.
