TJ AEROSENSE • T100 OWNER RESOURCE

Keep the T100 working. Catch the little stuff first.

DJI Agras T100

Regular inspection and maintenance helps keep your DJI Agras T100 reliable, accurate, and ready when you need it. We built this guide as a practical quick-reference for routine inspections, cleaning, scheduled maintenance, and major service intervals.

Maintenance intervals should be adjusted for actual operating conditions. Heavy use, fertilizer exposure, corrosive products, dust, residue, or unusually harsh conditions may require more frequent inspection or service.

View maintenance schedule Request T100 service

The simple rule Use the interval that comes first.

If a component is listed by both calendar time and aircraft hours, flights, cycles, or charges, inspect it when the first threshold is reached.

QUICK REFERENCE

T100 maintenance schedule

Start here. Pick the interval that applies to your aircraft, then jump to the detailed checklist below.

01 Before & after each operating dayArms, locks, radar cleanliness, hoses, connections, strainer, liquid-level system, vent valve and spray-system flushing. 02 Monthly / 100-hour serviceFrame hardware, motors, propellers, clamps, wiring, battery, pumps, sprinklers and flowmeter. 03 Every 6 monthsDeeper frame, radar, control-board, electronics, ESC, positioning and spray-tank inspection. 04 Every 12 monthsAnnual inspection including landing gear, FPV/vision systems and the recurring lower-interval checks. 05 Major service milestones500-hour pump head, 1,000-hour pump motor, battery cycle guidance and high-hour aircraft review.

ROUTINE CHECKS

Before & after every operating day

A few minutes of inspection can catch loose hardware, wear, leaks, damaged wiring or contamination before it turns into downtime.

Operator check

Aircraft

Inspect the battery slider, pads, rollers, hooks and retaining clips for damage or abnormal wear.
Inspect aircraft arms and carbon tubes for cracks, coating damage or other visible damage.
Check arm locks and frame latches for cracks, deformation or abnormal looseness.
Keep the laser-radar window clean and free of chemical residue, fertilizer and dust.

Operator check

Spray system

Inspect spray hoses for wear, pinching, cracking or other damage.
Check hose connections for leaks and damaged seals.
Inspect and clean the strainer as needed.
Check the continuous liquid-level gauge and its hose.
Confirm the solenoid vent valve opens and operates normally.

Flush the spray system after each operating day.

Use clean water and thoroughly rinse the tank and plumbing. The source maintenance recommendation calls for rinsing the spray tank with clean water at least twice after daily operations. After thicker or difficult products, use an appropriate cleaning solution and make sure residue is removed before storage.

HIGH-USE SERVICE

Monthly & 100-hour inspection

For high-acre operators, aircraft hours can arrive before the calendar interval. Use whichever threshold comes first for the component being inspected.

Aircraft structure

Power-distribution-board connector
Middle-frame structure and mounting hardware
Landing-gear mounting screws
Radar mounting/support structure
Aircraft-arm mounting hardware

Power system

Motor condition and abnormal operation
Propellers for wear, damage or deformation
Propeller clamps and mounting condition
Aircraft-arm power wiring

Battery

Inspect the standard flight battery approximately every 100 charge cycles or one month. Check for swelling, dents, deformation and terminal contamination.

Spray system

Delivery pump - about every 100 hours or one month, plus regular post-operation cleaning
Centrifugal/mist sprinkler - about every 100 hours or one month
Flowmeter - monthly inspection

Generator

Inspect approximately every 200 charges or one month, including the case, battery terminals, fan and cooling system. Clean accumulated debris as needed.

New-aircraft 100-flight check

Motor, propeller, propeller-clamp and aircraft-arm power-line inspections begin after the first 100 flights, then continue at the recurring interval shown in the maintenance recommendation.

DEEPER INSPECTION

6-month service

These checkpoints include components that may require disassembly, electrical inspection or additional diagnostic testing. TJ Aerosense recommends handling these as scheduled dealer-service items.

6 month / 300 hour group

Frame & structure

Middle frame - front & rear
Key structural attachment points
Inspect for cracks, deformation, corrosion or looseness

6 month / 300 hour group

Electronics & sensing

Front radar
Payload control board
Payload adapter board
Aerial electronics and ESC
SDR antenna and RTK module

6 month / 300 hour group

Spray tank & related components

Inspect the spray tank and mounting condition
Check for wear, leaks, residue and chemical damage
Continue all lower-interval spray-system cleaning and inspection

Schedule T100 service

ANNUAL REVIEW

12-month inspection

Annual service should include the scheduled monthly and six-month checkpoints along with a complete review of the aircraft structural, electrical, sensing, power and spraying systems.

12 month / 600 hour group

Annual-specific items

Landing gear and the FPV / multi-camera vision system are specifically listed at a 12-month inspection interval.

12 month / 600 hour group

Roll up lower-interval checks

The annual service should include the recurring monthly, 100-hour and six-month items rather than treating the 12-month rows as the only annual checks.

MAJOR SERVICE MILESTONES

Plan ahead for high-hour components

Use these milestones as planning points and confirm current DJI guidance and actual component condition before replacement.

500 HOURS

Delivery pump head

Recommended replacement interval for the delivery-pump head assembly.

1,000 HOURS

Delivery pump motor

Recommended replacement interval for the delivery-pump motor.

1,500 CYCLES

T100 flight battery

Maximum cycle guidance listed for the standard flight battery. Battery condition still needs to be monitored throughout its service life.

700 HOURS / 36 MONTHS

High-hour aircraft review

The maintenance recommendation uses 700 operating hours / 36 months as maximum replacement guidance for many aircraft components. We recommend a comprehensive condition-based inspection at this point to determine what should actually be serviced or replaced, rather than treating it as an automatic full-aircraft replacement list.

FIND IT BY SYSTEM

Maintenance by aircraft system

Use these expandable sections when you want to look up a specific part of the aircraft rather than a service interval.

Aircraft structureFrame, arms, locks, landing gear & fasteners

Routine: battery slider, arms, arm locks and frame latches.

Monthly: distribution-board connector, middle-frame structure, key mounting screws, landing-gear fixing screws, radar support and arm hardware.

6 months: front/rear middle-frame inspection.

12 months: landing-gear inspection.

Power systemMotors, propellers, clamps & arm wiring

Several power-system items receive an initial inspection after the first 100 flights, then recur around the 100-hour / monthly interval. Inspect sooner after motor stalls, abnormal noise, impact or motor/ESC temperature warnings.

Radar & vision systemsLaser radar, front radar, FPV & positioning

Routine: keep the laser-radar window clean using clean water, compressed air or a lint-free cloth as appropriate. Avoid harsh chemical agents and do not disassemble the radar dome for routine cleaning.

6 months: front radar, SDR antenna and RTK module.

12 months: FPV / multi-camera vision system.

Battery & electricalBattery, connector, boards, ESC & electronics

Monthly: battery connector and standard battery; battery inspection is also tied to approximately 100 charge cycles.

6 months: payload control board, payload adapter board, aerial electronics and ESC.

Spraying systemTank, hoses, pump, sprinklers, strainer & flowmeter

Before operation: hoses, hose connectors, strainer, continuous liquid-level gauge and solenoid vent valve.

After operation: flush the spray system and rinse the tank thoroughly.

100 hours / monthly: delivery pump and centrifugal/mist sprinklers.

Monthly: flowmeter.

6 months: spray-tank inspection in addition to daily cleaning.

Remote controllerMonthly inspection

Inspect the remote controller monthly for physical damage, connector condition and normal control operation. Keep the unit clean and protected from chemical contamination.

Generator200 charges or monthly

Inspect the generator case, battery terminals, fan and cooling system approximately every 200 charges or one month. Clean debris and confirm cooling airflow is unobstructed.

WHO SHOULD DO IT?
