# Maintenance

### Mechanical maintenance UAV

* **Standard Maintenance:**\
  Address every 10 to 20 flight hours or 30 to 50 flights, whichever comes first, depending on operational conditions.
* **Detailed Inspections:**\
  Perform every 50 to 100 flight hours or 100 to 200 flights, whichever comes first, depending on operational conditions.
* **Full Maintenance:**\
  Required after 500 flight hours
* **After Crash Inspection**

  Required after low to semi-intensity crashes, where only propellers and legs were broken.

### Standard Maintenance

1. **Propellers**
   * Check propellers for structural damage. If damaged, replace them.
   * Check four motor screws on the propellers that mount them to the motor. Tighten if needed.
   * Check two screws securing the foldable propellers. The propellers should be unfoldable with low force. Adjust screws as necessary.
2. **Arm Lock-in Mechanism**
   * Inspect the arm lock-in mechanism.
   * Check for dirt blocking the full lock-in.
3. **360° Camera Connector**
   * Check the 360° camera connector. If the pins are damaged, straighten them.
4. **Legs and Mounts**
   * Check the legs. If they fit too tightly or too loosely, try to replace them between mounts or clean the metal ball bearing. Replace if damaged.
5. **Overall UAV Inspection**
   * Inspect the entire UAV for structural damage.
6. **Tightening of the antenna connectors on the UAV**
   1. Ensure the antenna connectors are not loose. If they are, use pliers to hold the nut and tighten it.
7. **Clean all lenses of the sensor system**
8. **Clean all ventilation holes**

### Detailed Maintenance

* Review all items from the standard maintenance checklist.
* Inspect the bearings of the motors. Listen for unusual sounds and vibrations; check for dirt or similar issues if detected.
* Examine the payload gimbal for erratic movement during its initialization phase.

{% hint style="info" %}
The UAV backpacks include all the necessary tools for disassembling, tightening, and loosening screws. Tool for tightening antenna connectors is missing.
{% endhint %}

***

### **Full Maintenance**

After this interval, the motors are expected to be worn out and need to be replaced. The same applies to other moving parts of the system. Please contact support for the next steps.

***

### After crash inspection

Assess whether the crash is fatal or not. Damage to propellers or landing legs may be repairable on the spot. The gimbal can be swapped between UAVs within the system. Damage to foldable arms might be repairable; please contact support for further instructions.

Carry out a full and detailed maintenance procedure.

{% hint style="warning" %}
Please note: In the event of a crash, full operational capability of the system cannot be guaranteed.
