Repair procedures: DJI Mavic 2

Replace a propeller

When a propeller is chipped, cracked, bent or loose — never fly on a damaged one.

1. Switch the drone off first. DJI's repair manuals say never to install or remove a battery while the drone is on. Then remove the battery.
2. Propellers are marked to match their motors — depending on the model, by a white ring or another mark. Note which motor each one belongs to.
3. To remove: press the propeller down onto the motor and rotate it in its release direction until it lifts free. The lock and release directions are shown on the propeller hub.
4. To fit: place the new propeller on its matching motor, press it down, and rotate it in the locking direction until it locks in place.
5. Tug each propeller gently upward to confirm it's locked before flying.

Fit and remove the battery

Before and after every flight, and whenever you swap batteries.

1. Switch the drone off first. DJI's repair manuals say never to install or remove a battery while the drone is on.
2. Your user manual shows exactly how this model's battery latches. We haven't confirmed the mechanism for this model, so we won't guess at it.

Calibrate the compass

When the app asks, after travelling a long distance, or if the drone drifts or shows a compass error.

1. Go outdoors, well away from cars, buildings, metal structures and power lines. Take keys and other metal objects out of your pockets.
2. In DJI GO 4, open the aircraft settings and start compass calibration.
3. Hold the drone level and turn a full circle until the app says to stop.
4. Hold it vertically, nose pointing down, and turn a full circle again.
5. If it fails, move further from any metal and try again.

Exact menu locations vary by app version — the app walks you through each step.

Calibrate the IMU

When the app asks, after a hard landing, or if the drone won't fly level.

1. Work indoors on a flat, level surface, with the drone at room temperature.
2. In DJI GO 4, open the aircraft status page and start IMU calibration.
3. Place the drone in each position the app shows and keep it perfectly still until each step finishes.
4. Don't move or bump it during calibration.

Exact menu locations vary by app version — the app walks you through each step.

Calibrate the gimbal

If the horizon looks tilted, the camera drifts, or after any gimbal repair.

1. Remove the gimbal cover or clamp.
2. Put the drone on a flat, level surface and power it on.
3. In DJI GO 4, open the gimbal settings and choose auto-calibration.
4. Don't touch the drone or camera until calibration finishes.

Exact menu locations vary by app version — the app walks you through each step.

Calibrate the remote controller

If the control sticks don't return to centre, or the drone doesn't respond correctly to your inputs.

1. Connect the controller to the app.
2. Run the remote controller calibration and move the sticks as prompted.
3. DJI's repair manual lists this as the fix for sticks that don't re-centre. If calibration doesn't cure it, DJI's method is to replace the controller.

Update or reinstall firmware

When the app prompts an update, after an update fails, or if the drone misbehaves after one.

1. Update through the app whenever prompted. Update the drone, the controller and every battery — mismatched versions cause connection and battery errors.
2. Keep the battery charged and don't disconnect or power off mid-update.
3. If an update fails or the drone won't start afterwards, connect it to a computer with DJI Assistant 2 (DJI's download page lists the right version for your drone), open the firmware section, and reinstall.
4. Use a good-quality data cable — charge-only cables won't work.

The drone stays powered on and connected throughout — like the calibrations above, this is done with the drone switched on.

Clean the camera and sensors

If footage looks hazy, or the app reports a vision or obstacle-sensing error.

1. Switch the drone off.
2. Wipe the camera lens and every vision sensor gently with a clean microfibre cloth. Don't use solvents or press hard.
3. Check for dust in the sensor windows, and for smudges you can't see until you look at an angle.

Store batteries safely

Between flights and for longer storage.

1. Store batteries somewhere dry, between 0°C and 45°C, away from heat and out of reach of children.
2. Keep them away from metal objects such as keys, coins and jewellery, which can short them.
3. Fly only between -10°C and 40°C. Warm cold batteries to room temperature before flying.
4. Never use, charge or transport a battery that is swollen, leaking or damaged. Don't put batteries in regular household rubbish.
