Season-start field readiness
Ready the T50
before the first field job.
A practical return-to-service inspection for Canadian operators bringing a DJI Agras T50 out of winter storage—designed to identify visible damage, contamination and setup issues before the first spray or spread job.
Start with a clean, unpowered aircraft on a stable work surface. Review current DJI documentation for the exact configuration in use.
This DJI Agras T50 maintenance checklist is a methodical season-start review of the aircraft, payload, power system and field kit before field time becomes expensive.
Begin with the parts that carry the load.
Airframe &
propulsion
Clean the aircraft first. A clean surface makes cracks, loose hardware, residue and rubbed-through areas much easier to see.
- Unfold each arm and confirm its locking mechanism fully engages; look for unusual movement, damage or distortion.
- Inspect every propeller for cracks, chips, deformation, delamination, loose fitment or chemical residue.
- With the aircraft powered down, inspect motors for external damage, contamination, loose parts and abnormal resistance or roughness. Do not force a motor to turn.
- Trace visible wiring and connectors around the arms, motors, landing gear and payload interfaces for pinching, abrasion, exposed conductors or residue.
- Inspect the front and rear radar surfaces and binocular vision sensors for cracks, obstruction, residue or contamination; clean them only as DJI directs.
- Check landing gear, tank mounting areas and payload interfaces for damage, looseness or residue.
- Confirm the correct propeller is installed in the correct position before flight.
Clean first. Inspect before mixing product.
Spraying system
Inspect the spray equipment only after it has been cleaned and made safe according to the chemical label and DJI instructions. The aim is to catch leaks, restricted flow paths and damaged components before work begins.
Inspection focus
Hoses, nozzles & filters
Use a clean visual inspection to check hose routing, nozzle assemblies and serviceable filters for residue, blockage, wear, damaged seals or loose connections.
- Inspect the spray tank, cap, seals and drain area for cracks, damaged threads, residue and signs of leakage.
- Follow each hose from tank to pump and nozzle; check for kinks, soft spots, abrasion, loose clamps and residue around joints.
- Check delivery pumps and visible wiring/connectors for damage, contamination and secure fitment.
- Inspect nozzles and filters for blockage, wear, damaged O-rings or contamination; clean or replace only as DJI directs.
- Complete the applicable system check using current app and manual guidance before a work day.
- Do not operate with a suspected leak or irregular system indication.
For dry-granule work.
Spreading system
If your season includes dry-granule work, inspect the DJI Agras T50 Spreading System before installing material. Remove stored residue and moisture before they interfere with the gate or rotating components.
Inspection focus
Gate, hopper & mounting
Check the hopper, gate and installation points for dry, clean movement and positive attachment before a calibration or field operation.
- Inspect the hopper and lid for cracks, residue, moisture and secure mounting.
- Confirm the gate moves as commanded and does not bind, stick or remain partly open.
- Inspect the spinner disk and surrounding area for damage, buildup or anything that could obstruct rotation.
- Use the current DJI procedure and intended material to complete any required calibration check before application.
Inspect each battery individually.
DB1560 batteries
Each DB1560 Intelligent Flight Battery deserves an individual inspection. Keep batteries clean, dry and disconnected while checking them.
Inspection focus
Case, vents & terminals
Inspect the case, handles, vents and terminals in good light. Look for impact damage, deformation, corrosion, contamination or damaged contact surfaces.
- Inspect the battery case, handles and locking interfaces for impact damage, deformation, cracks or loose components.
- Inspect terminals, communication contacts, ports and protective covers for corrosion, residue, moisture or physical damage.
- Confirm there are no unexplained battery, charger or app warnings before returning the battery to service.
- Review how the battery was stored and follow current DJI charging and return-to-service guidance before field use.
- Inspect the battery cooling equipment, airflow path, fan area and connecting cable before the first charging cycle.
- Keep batteries isolated from conductive materials, moisture and damaged equipment during transport and staging.
Treat the charging setup as one connected system.
Charger, generator
& cooling
Inspect the C10000 Intelligent Power Supply, D12000iE Multifunctional Inverter Generator where used, battery cables/connectors and cooling equipment in your setup.
- Check enclosures, handles, vents, controls and visible fasteners for physical damage, contamination or obstructed airflow.
- Inspect AC leads, charging leads and connectors end to end for cuts, crushed sections, heat damage, bent contacts, loose fitment or residue.
- Check cooling equipment housing, fan/air path and cable condition. Keep air paths clear and follow equipment-specific setup instructions.
- For the generator, use the manufacturer’s current operating and maintenance guidance.
- Do not start or connect equipment with damaged cables, a suspected fuel/engine issue or an unresolved warning.
Check the information, not only the hardware.
Controller &
firmware
- Inspect DJI RC Plus exterior, screen, sticks, buttons, antennas, ports, charging connection and battery status.
- Confirm the controller is linked and that the aircraft, payload configuration and controller present normal status.
- Back up and review maps, field boundaries, obstacle/exclusion areas, task data and application settings; verify the correct farm, field and operation type.
- Review release notes and use the current DJI firmware workflow. Plan updates with time for checks and validation.
- Avoid making an untested update the last step before a critical job.
Prepare for ordinary issues; leave repairs to qualified service.
Field spares
- Correct replacement propellers and relevant DJI-approved installation items for your configuration.
- Clean spare nozzles, filters, seals/O-rings and compatible hose/connectivity parts for the spray setup.
- Spreading-system accessories and serviceable parts appropriate to the hopper/gate configuration in use.
- Clean water, approved cleaning supplies, soft lint-free cloths, protective caps and secure storage for clean parts.
- PPE required by the product label and your operating procedure.
- A charged communications device, current manuals/digital records, and a clear path to technical support.
The final readiness pass.
15-minute pre-flight
walkaround
This quick pass is the final readiness check—not a substitute for the deeper pre-season inspection or DJI’s pre-flight procedure.
- Look around and under the aircraft. Clean airframe, locked arms, stable landing gear, clear radar/vision surfaces, and no fresh residue or visible damage.
- Check propulsion. Correct, undamaged propellers; clean motors; no loose or damaged visible wiring.
- Confirm the payload. Correct spray or spreading system installed, tank/hopper secure, no visible leaks or obstructions.
- Check the battery and power kit. Correct DB1560 installed, no abnormal case/terminal condition, undamaged charging and cooling cables.
- Open the RC Plus and app. Normal connection/status, correct field and task data, and no unresolved alerts.
- Stage the field kit. PPE on hand, clean spares accessible and a plan to stop if an abnormality appears.
A clear stop rule
When to stop
& escalate
Stop the operation, isolate the affected equipment and seek qualified help if you find a cracked or distorted airframe/arm, damaged propeller or motor, damaged wiring, a leak, a gate or spinner that does not operate normally, a swollen/leaking/abnormally hot battery, damaged power cables, an unresolved warning, or unexplained abnormal behaviour in the app. Do not improvise repairs, bypass warnings or continue simply because the job is scheduled.
Common questions
FAQ
Quick answers for the first inspection after storage and before the first application day.
What should be checked first on a DJI Agras T50 after winter storage?
Start with a clean, unpowered visual inspection of the airframe, arm locks, propellers, motors, wiring, radar and vision surfaces, tank/payload interfaces and DB1560 batteries. Then inspect the spraying or spreading system and charging setup before placing the aircraft into service.
Can I fly if a DB1560 battery looks swollen or becomes unusually hot?
No. Remove it from service and follow current DJI battery guidance. Do not fly, charge or continue using a battery with swelling, leakage, damaged terminals, unusual temperature or unresolved warnings.
How do I prepare the T50 spraying system for the season?
Inspect the tank, seals, drain area, hoses, pumps, nozzles and filters after appropriate cleaning. Look for damage, residue, blockages and leaks, then follow DJI’s current system-check and maintenance procedure before operation.
What should I inspect on the T50 Spreading System?
Inspect the hopper, mounting points, gate and spinner disk for damage, moisture, residue or obstruction. Confirm the gate moves correctly and use the current DJI procedure for the material-specific calibration check.
Should I update firmware on the morning of a field job?
Plan firmware work early enough to review release notes, back up task data and complete DJI’s required checks. Avoid making an untested update the last action before a time-sensitive operation.
