Drone Maintenance

1. Daily/Weekly Maintenance Checklist

Regular maintenance keeps the drone safe, reliable, and ready for operation.

Daily Checks:

• Inspect propellers for cracks or bends
• Check motors for smooth rotation
• Verify battery health and charge levels
• Authenticate GPS and sensor status
• Check spray tank, pipes, and nozzles
• Ensure remote controller functioning
• Look for loose screws, mounts, and landing gear stability

Weekly Checks:

• Deep cleaning of motors and drone body
• Check all cables and connectors
• Inspect firmware versions
• Test spray system thoroughly
• Calibrate compass and IMU if required
  Routine checks reduce breakdowns and extend drone life.

2. Cleaning Motors, Filters & Nozzles

Dirt buildup affects drone performance. Cleaning must be performed carefully.

• Motors:
  Use a soft brush or compressed air to remove dust and debris.
  Avoid applying liquids directly to motors.
• Filters:
  Spray systems have filters—clean them after every spraying session to prevent clogging.
• Nozzles:
  Remove nozzles and flush with warm water.
  Use a soft brush to clear chemical deposits.
  Never use sharp objects to clean nozzles, as it changes droplet size.

Proper cleaning ensures smooth operations and accurate spraying.

3. Battery Maintenance and Storage

Drone batteries are expensive and must be handled carefully.

• Charge batteries only with recommended chargers
• Never overcharge or leave on charge unattended
• Allow batteries to cool before charging after a flight
• Store batteries at 40–60% charge for long periods
• Keep batteries away from direct sunlight or high heat
• Do not use swollen or damaged batteries

Good battery care increases flight time and safety.

4. Firmware Updates

Firmware updates improve drone stability and features.

• Check for updates via the drone app
• Ensure strong internet connection before updating
• Update:
  • Flight controller firmware
  • Remote controller firmware
  • Battery firmware (if applicable)
  • Application software

Updating ensures better performance, bug fixes, and compliance with regulations.

5. Troubleshooting Common Errors

Drone operators must understand basic troubleshooting.

• GPS Signal Weak:
  Move away from buildings, metal objects, or overhead wires.
• Compass Error:
  Recalibrate compass; avoid magnetic interference.
• Motor Overload:
  Check propellers and motor shafts for debris.
• Battery Voltage Error:
  Replace or recharge battery properly.
• Spraying Not Working:
  Check pump, pipes, nozzles, and filter for blockages.

Quick troubleshooting avoids delays and flight cancellations.

6. Logbook & Service Documentation

Record-keeping is mandatory and helps track drone condition.

A logbook should include:

• Flight hours
• Maintenance activities
• Battery cycle count
• Firmware updates
• Repair details
• Spray volume and chemical usage

Proper documentation ensures compliance, warranty validity, and accurate maintenance scheduling.
