Maintenance Manual 

[V1.0j 2015.2 

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. Checking the Battery 

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 

tor disposal. 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 a more 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. Check the contact pins in the battery compartment to 

ensure that the pins are clear. They should be able 

to establish easy contact with the battery connectors 

and should not be 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 during flight. 

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 

being damaged. 

9. Run the DJI Pilot App to confirm that all battery cells 

are at similar voltage levels and stay at the 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 lower than the others, contact OJI for analysis. You 

can also check the battery cell warning history. If any 

warning are reported, contact DJI. 

II. Checking the Transformation System 

1. Check the servomotor cables for wear. Also confirm 

that the 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 

if they show signs of rust. 

3. Listen to the servomotors during the transformation, 

if there is abnormal noise, it may indicate that the 

servomotors worn. 

4. After the landing gear rises, check the lead screws 

and bearings. If any dirt or dust is found, clean and 

grease the bearings. 

5. Check the lead screws. If there is any scratches, 

dents, or plastic particles underneath them, contact 

DJI Support to arrange repairs. 

Ill. Checking the Aircraft 

1. Confirm that all the screws are still adequately 

tightened. 

2. Check the aircraft for breaks or damage. If there is 

any reason to believe that detectable damage might 

affect flight safety, con suit with DJi Support. 

3. Check the carbon tubes of the arms for damage. 

4. Check the dampers on the landing gears. If they are 

loose, secure them with 502 glue. 

5. Ensure that there are no obstacles on or around the 

GPS module or around the antennas on the landing 

gear. Remove any obstacles (such as tapes with 

conductive material) that might affect or block the 

signal. 

6. Check that the right and left landing gear rest at the 

same tilt angle. 
IV. Checking the 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. Detach the propellers and start the 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 DJ I Support to order 

replacement motors. 

4. Check for deformities by confirming that the gap 

between the motor and motor base is even. If not 

contact DJI Support to 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 DJ I to repair any 

broken plastic components. 

V. Checking the Propellers 

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

breakage or cracking on a propeller, do not use it. 

2. Attach the propeller to the motor, turn on the aircraft, 

and place it on the ground. Stand 1 meter away from 

the aircraft and observe the rotating propellers. If you 

can see two distinct propeller outline layers, when 

looking at a spinning propeller from the side, this 

propeller is damaged and should not be used. 

VI. Checking the IMU 

1. Open DJI Pilot app to check the condition of the 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 not touch the craft during the calibration. 

2. Turn on the aircraft and 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. Checking the Control and Video Transmission System 

Check the 4 antennas on the landing gear to ensure 

that they are secure. Also check for 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. Checking the Gimbal and Camera 

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

particularly vulnerable component. If the gimbal 

fails to initialize when 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 

gimbal quick-mount. 

2. Check the metal contacts on the quick mount 

connector board, if any contact is bent, replace 

the quick-mount connector. 

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 that the 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. Checking the Vision 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 that the Vision Positioning System is securely 

installed on the 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, the Vision Positioning System should function 

normally.
