Maintenance Manual

V,. ~ 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 ballery for tlamage and deformities. If there are any signs of damage to the battery, stop using it antl discharge the baltery to 10% or below for disposal. Do not disassemble the battery for any 

### reason. 2. Check the baltery pins and rub lhem clean with an eraser it any residue is observetl. This will help to ensure a more reliable connection. 3. Check the metal battery power connectors for damage. If the conneclors appear burnl, 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 batlery companment to 

### ensure Ihatthe pins are clear. They should be able to establish easy contact with the ballery connectors and should not be bent. 5. Check the electrodes on the battery. If they appear burnt, polish them with sandpaper. If lhere 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 batlery from becoming loose during (light. 7. Check the power cables between the arms antl the center plate, if the cables are worn, contact DJI to arrange repairs. 8. For long term storage, please refer to the '9ntelligenl Flight Battery Safety Guidelines` and check the battery once a month to prevent the ballery cell from being damaged. 9. Run the DJI Pilot App to confirm that all battery cells are at similar vollage 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 DJI for analysis. You can also check the battery cell warning history. If any warning are reported, contact DJI. II. CheckingtheTransformetionSystem 1. Check Ihe servomolor cables for wear. Also confirm that the connection points are still in good condition. 2. Check the lead screws antl contact DJI Support to arrange repairs if any bending or damage is tliscoveretl. Clean the leatl 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. Afler the landing gear rises, check the lead screws and bearings. If any din or tlust is found, clean and grease the bearings. 5. Cheok the lead sorews. If there is any scratohes, dents, or plastic particles underneath them. contact DJI Support to arrange repairs.

III. Checking the Airerafl i. Confirm that all Ihe screws are still adequately lighlenetl. 2. Check the aircrafl for breaks or damage. If there is any reason to believe Ihal deteclable damage might affect flight safety, consult wilh DJI Suppan. 3. Check the carbon tubes of the arms for damage. 4. Check the dampers on the landing gears. If they are loose, secure themwilh 502 qlue. 5. Ensure that there are no obstacles on or around the GPS module or arountl the antennas on the landing gear. Remove any obstacles (such as tapes with conduclive material) Ihat might affecl or black the signal. 6. Check that the righl and left landing gear rest at the same till angle.

# EXHIBIT BIV. Checking the Motors 1. Check the rotors to confirm that they have nol becomeloose. 2. Detach the propellers and start the motors. Listen carefully. If there is any abnormal noise, please replace the motors. Thls may be a sign that the bearings have been worn out. 3. Detach the propellers antl starl 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 DJI Supporl to order replacement motors. 4. Check for deformities by confirming that the gap belween the motor and molor base is even. If nol contact DJI Support to order replacement motors. 5. Ensure that the screws used to secure the motor base are light and the plastic components around the motors are in good condition. If not please tighten the screws antl contact DJI 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, tlo not use il. 2. Atlach the propeller to the motor, turn on the aircrafl, and place it on the ground. Stand 1 meter away from the aircraft and abserve 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 ativanced IMU calibration. Please place lhe aircrafl in a cool environment and on a flat, stable sudace (il the lantling 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 irregularily is detected, replace the fan.

VII. CheckingiheControlandVldeoTransmissionSystem 1. Check the 4 anlennas on Ihe landing gear to ensure thal they are secure. Also check for any bentling or damage. 2. Check the antennas of the remote controller for damage 3. Check the neck strap for tlamage or wear, replace if necessary. VIII. Checking the Gimbal antl Camera 1. The quick-mounl connector for the camera is a particularly vulnerable component. If the gimbal fails to inilialize when turned on,fails to work after initialization, or lails to transmil video to the app (whlle OSD data is displayed), the quick-mount conneclor may be worn. In this case, replace the rubber mat, circuit board, and/or connector on the gimbal quick-mount. 2. Check the metal contaots on the quick mount connector board, if any contact is benl, replace lhe quick-mount conneclor. 3. Check the contact pins on the quick-mount connector boartl, if there is any tlirt, rub it clean with an eraser.lf any conlacl pins are worn oulit 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. Lislen for any abnormal noise from the fan when the gimbal is turned on. This may indicate unusual vibralion and Ihe fan shoultl be replaced.

IX. Checking the Vision Positioning System 1. Check the lens of the camera. It any dirt or residue is detected, gentlyclean 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 antl turn on the aircraft. Hold lhe aircraft 1-2 meters above a surface wilh rich patterns, under gootl 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 antl indicates that P-OPTI mode is active, the Vision Posilioning System should function normally.
